Provider to perform any Non-Included System Services, then the Company will submit a written request for such services to Provider. If Provider agrees to provide the Non-Included System Services, it will do so in accordance with the provisions of
this Agreement. Provider will not perform Non-Included System Services until the Parties have reached agreement in writing setting forth what the Non-Included System Services will cost. Notwithstanding the foregoing, if Provider determines, in

Emergency Services in accordance with the provisions of this Agreement. The Company shall reimburse Provider for all reasonable expenses associated with Provider’s performance of any such Emergency Services, except to the extent such Emergency

Section 4.1 Indemnification of Provider by the Company. The Company will indemnify, defend and hold harmless Provider, its
officers, directors, employees, members, partners, Affiliates and agents (each, a “Provider Indemnitee”) from and against any and all Indemnifiable Losses asserted against or suffered by any Provider Indemnitee in any way relating
to, resulting from or arising out of or in connection with any Third Party Claims against a Provider Indemnitee, in each case, to the extent arising out of or in connection with (i) the gross negligence, fraud or willful misconduct of the
Company, its Affiliates or its Subcontractors (other than Provider), (ii) any breach by the Company of any of the representations, warranties or covenants of the Company under this Agreement or (iii) a default under the Customer Agreement
as a result of a breach by the Company of its obligations hereunder; provided that in each case, the Company will have no obligation to indemnify Provider with respect to any Indemnifiable Losses resulting from (a) the gross negligence,
fraud or willful misconduct of Provider, its Affiliates or its Subcontractors (other than the Company), (b) the breach by Provider of any of its covenants or warranties under this Agreement, or (c) so long as the Managing Member is an
Affiliate of Provider, the breach by the Managing Member of any of its covenants or warranties under the LLC Agreement. 
 Section 4.2
Indemnification of the Company by Provider. Provider will indemnify, defend and hold harmless the Company, its officers, employees, members, partners, Affiliates and agents (each, a “Company Indemnitee”) from and against any
and all Indemnifiable Losses asserted against or suffered by any Company Indemnitee in any way relating to, resulting from or arising out of or in connection with any Third Party Claims against a Company Indemnitee, in each case, to the extent
arising out of or in connection with (i) the gross negligence, fraud or willful misconduct of Provider, its Affiliates or its Subcontractors, (ii) any breach by Provider of any of the representations, warranties or covenants of Provider
under this Agreement or (iii) a default under the Customer Agreement as a result of a breach by Provider of its obligations hereunder; provided that in each case, Provider will have no obligation to indemnify the Company either with
respect to any Indemnifiable Losses resulting from the gross negligence, fraud or willful misconduct of the Company, its Affiliates or Subcontractors (other than Provider) or the breach by the Company of any of its covenants or warranties under this
Agreement. 
 Section 4.3 Indemnification Procedures. Each of the Company’s obligations in Section 4.1 and
Provider’s obligations in Section 4.2 above (each of Company and 

  
 15 

 
Provider, as applicable, the “Indemnifying Party”) are contingent upon the Provider Indemnitee or the Company Indemnitee, as applicable (each, the “Indemnitee”),
promptly notifying the Indemnifying Party in writing of the Third Party Claim and, except with respect to Taxes, promptly tendering the control of the defense and settlement of any such Third Party Claim to the Indemnifying Party at the Indemnifying
Party’s expense and with the Indemnifying Party’s choice of counsel. In connection with the foregoing, the indemnification obligation of Indemnifying Party to the Indemnitee shall be reduced if and to the extent the failure of an
Indemnitee to provide such notice and tender of control actually prejudices the outcome of any such claim; provided, however, that the foregoing notice requirement shall not apply if Provider or one of its Affiliates is the Managing
Member at such time. The Indemnitee shall also cooperate with the Indemnifying Party, at the Indemnifying Party’s expense, in defending or settling such Third Party Claim and the Indemnitee may join in defense with counsel of its choice at its
own expense. An Indemnifying Party may not, without the prior written consent (such consent not to be unreasonably withheld) of an Indemnitee, settle, compromise or consent to the entry of any judgment regarding a Third Party Claim the defense of
which has been assumed by the Indemnifying Party unless such settlement, compromise or consent (i) does not contain any admission or statement suggesting any wrongdoing or liability on behalf of the Indemnitee; and (ii) does not contain
any equitable order, judgment or term that in any manner affects, restrains or interferes with the business of the Indemnitee or any of the Indemnitee’s Affiliates. An Indemnitee may not settle, compromise or consent to the entry of any
judgment regarding any Third Party Claim for which indemnification is sought and the defense of which has not been assumed by the Indemnifying Party, without the prior written consent of the Indemnifying Party, such consent not to be unreasonably
withheld or delayed. Each Indemnifying Party’s obligations under Section 4.1 or Section 4.2, as applicable, shall survive the expiration or termination of this Agreement. 

ARTICLE V 
 FORCE
MAJEURE 
 Section 5.1 If either Party (subject to Section 3.2(a)(iii) in the case of Provider) is rendered wholly
or in part unable to perform its obligations under this Agreement because of a Force Majeure Event, then such Party will be excused from whatever performance is affected by the Force Majeure Event; provided that: 

(a) such Party will, as soon as is reasonably possible but in any event no later than ten (10) Business Days (i) upon the occurrence
of the Force Majeure Event, give the other Party written notice describing the particulars of the occurrence, and (ii) after termination of the Force Majeure Event, give the other Party written notice summarizing the effects of the Force
Majeure Event and the actions taken in connection therewith; 

  
 16 

 (b) the suspension of performance will be of no greater scope and of no longer duration than is
required by the Force Majeure Event; 
 (c) no obligation of such Party that arose before the occurrence causing the suspension of
performance and that could and should have been fully performed before such occurrence through the exercise of commercially reasonable efforts or pursuant to the terms of this Agreement will be excused as a result of such occurrence; and 

(d) no Force Majeure Event shall excuse any Party from its payment obligations under this Agreement. 

ARTICLE VI 

LIMITATIONS ON LIABILITY

(a) In no event will any Party be liable under this Agreement to another Party for any lost profits (other than revenues from Customer

such liability of a Party to another Party under any other agreement between the Parties; provided, further, that a loss, disallowance or recapture of, or inability to claim, Tax Credits or accelerated depreciation or cost recovery
deductions shall not be treated as consequential, special, incidental, exemplary, statutory or punitive damages for purposes of this Agreement. 

(b) In no event will one Party be liable under this Agreement to the other Party for an aggregate amount in any given year in excess of the
Maximum Liability for such year unless and to the extent such liability is (i) the result of (A) fraud, gross negligence or willful misconduct of a Party, (B) the failure of a Party to pay any amount due under this Agreement or

accordance with the law of the State of New York applicable to contracts made and to be performed in the State of New York. THE PARTIES HEREBY IRREVOCABLY SUBMIT TO THE NONEXCLUSIVE JURISDICTION OF ANY STATE OR FEDERAL COURT IN NEW YORK WITH RESPECT
TO ANY ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT. EACH PARTY HERETO IRREVOCABLY AND UNCONDITIONALLY WAIVES TRIAL BY JURY IN ANY ACTION, SUIT OR PROCEEDING RELATING TO A DISPUTE AND FOR ANY COUNTERCLAIM WITH RESPECT THERETO.

 Section 9.4 Amendment, Modification and Waiver. This Agreement may not be amended or modified except by an instrument in
writing signed by the Party against which enforcement of such amendment or modification is sought. Any failure of a Party to comply with any obligation, covenant, agreement or condition contained herein may be waived only if set forth in an
instrument in writing signed by the other Party, but such waiver or failure to insist upon strict compliance with such obligation, covenant, agreement or condition shall not operate as a waiver of, or estoppel with respect to, any other failure.

 Section 9.5 Rights and Remedies. Each Party’s rights and remedies under this Agreement are intended to be distinct,
separate and cumulative and no such right or remedy therein or herein mentioned, whether exercised by such Party or not, is intended to be an exclusion or a waiver of any of the others. 

Section 9.6 Entire Agreement. This Agreement reflects the Parties’ entire agreement with respect to the matters covered by
the Agreement and supersedes any prior agreements, commitments, drafts, communication, discussions and understandings, oral or written, with respect thereto.

effective and valid under all Applicable Laws and regulations. If, however, any provision of this Agreement is prohibited by or invalid under any such law or regulation in any jurisdiction, it will as to such jurisdiction be deemed modified to
conform to the minimum requirements of such law or regulation, or, if for any reason it is not deemed so modified, it will be ineffective and invalid only to the extent of such prohibition or invalidity without affecting the remaining provisions of
this Agreement, or the validity or effectiveness of such provision in any other jurisdiction.

 Section 9.9 Counterparts. This Agreement may be executed in any number of
counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument. Delivery of an executed counterpart of a signature page of this Agreement by facsimile or other electronic transmission

 Section 9.10 Assignment. Neither Party
may assign its rights or obligations hereunder without the prior written consent of the other Party, which consent will not be unreasonably withheld, conditioned or delayed. Notwithstanding the foregoing, without the need for consent from the other
Party, (a) either Party may upon written notice transfer or assign this Agreement to any person or entity succeeding to all or substantially all of the assets of such Party or to a successor entity in a merger or acquisition transaction, and
(b) either Party may collaterally assign this Agreement to any of its lenders as security; provided, however, that any such assignee shall agree to be bound by the terms and conditions hereof. No assignment of such rights or
obligations may be made by either Party with respect to less than all of the Covered Projects.

Authorization. Notwithstanding anything in this Agreement to the contrary, Provider and the Company hereby agree and acknowledge that, with respect to any direction, consent or approval described in this Agreement that the Company may provide

good faith in establishing an escrow account with an independent escrow agent for the purposes of this provision.

additions will not constitute noncompliance with the requirements of this paragraph 3 or a breach of Provider’s undertaking hereunder for so long a period as may be necessary to remedy such failure, if such failure can be remedied, so
long as during such period Provider is using due diligence and best efforts to remedy such failure.

construction of this Agreement. For clarity, this Agreement shall not affect any orders of Products by Buyer under the Original Agreement that were acknowledged by Seller prior to the Effective Date, and the terms and conditions of the Original
Agreement shall continue to apply to such Products. 
 1.4 No Obligations Until Delivery of a Purchase Order. Prior to
Buyer’s issuance of a Purchase Order with respect to Products under this Agreement, and except with respect to Original Agreement Products: (a) no Products shall be delivered to Buyer; and (b) Buyer shall have no payment obligations

 2.1.1 Generally. Subject to this Section 2.1 and the delivery by Buyer to
Seller of a Purchase Order, Seller shall: (a) provide all of the Products specified in a Purchase Order in accordance with the provisions of this Agreement and such Purchase Order; (b) provide the Warranties with respect to the Products
delivered hereunder; and (c) perform its other obligations set forth in this Agreement and such Purchase Order. 
 2.1.2 Submission
of Purchase Orders. During the Term of this Agreement, and pursuant to the terms and subject to the conditions of this Agreement, Buyer may submit Purchase Orders to Seller for Products by electronic mail sent to Seller’s Representative.
Seller may change the electronic mail address to which Purchase Orders are sent at any time during the Term upon ten (10) Business Days’ prior written notice to Buyer. Each Purchase Order delivered by Buyer to Seller hereunder shall comply
with the Required Lead Time (subject to Section 4.1.1(b)) and shall: 
 (a) specify the model name of each Product, including
Seller’s Product number for such Product as set forth in Exhibit A, to be purchased by Buyer under such Purchase Order; 
 (b)
set forth the applicable quantity of each type of Product (“PO Product Quantity”) in compliance with Section 2.2; 

(c) set forth the applicable Unit Price for such Products determined in accordance with Section 3.1 and Exhibit A, and the
pricing for any other items or services (e.g., Enlighten pricing) on Exhibit A if and as applicable; 
 (d) include a Delivery
Schedule for Products being ordered under such Purchase Order in accordance with Section 2.1.5; and 
 (e) note the Delivery
Month to which the Purchase Order relates and whether the Purchase Order is for deliveries at the Destination Point occurring either (A) between the first (1st) through the fifth (5th) day of the Delivery Month, or (B) between
the fifteenth (15th) through the twentieth (20th) day of the Delivery Month, in each case pursuant to Section 2.1.5. 
 In the normal
course when Products are being ordered for delivery at Destination Points in a given Delivery Month, the Parties acknowledge that Buyer intends to provide two (2) Purchase Orders for each Delivery Month. One Purchase Order will cover Products
to be delivered to the applicable Destination Points between the first (1st) through the fifth (5th) day of the Delivery Month and the other Purchase Order will cover Products to be delivered to the applicable Destination Points between
the fifteenth (15th) and the twentieth (20th) day of the Delivery Month, in each case pursuant to Section 2.1.5. 

2.1.3 Acceptance of Purchase Orders; Obligation to Purchase and Sell. Seller shall use best efforts to accept and acknowledge the
Purchase Order using an Order Acknowledgement within two (2) Business Days of receipt of the Purchase Order, but in no event more than five (5) Business Days from such receipt; however, Seller may reject a Purchase Order if its
terms do not conform to this Agreement. The Order Acknowledgement shall include the Scheduled Ship Dates for the Products based on the Delivery Schedule submitted with a 

  
 3 

 
Purchase Order so that, taking into account customary and reasonable transit times for delivery to the Destination Point and subject to the occurrence of Force Majeure Events, such Products
ordered under the Purchase Order will arrive at the applicable Destination Points by the Delivery Dates set forth in the Delivery Schedule. Subject to the prior sentence and any other information required of an Order Acknowledgment (as defined), any
terms that appear in an Order Acknowledgement and that are either in addition to or conflict with the terms set forth in the Purchase Order or this Agreement shall be considered null and void, not a rejection and counteroffer, and the Order
Acknowledgement absent such terms shall constitute acceptance of the Purchase Order. This Agreement may not be amended in a Purchase Order. Should Seller reject a Purchase Order pursuant to this Section 2.1.3, Buyer may submit another
Purchase Order addressing any rejected Purchase Order and if submitted within ten (10) days of receipt of Seller’s rejection, the date of the accepted Purchase Order shall be the date of the originally rejected Purchase Order for purposes
of calculating the Required Lead Time. Upon acceptance of a Purchase Order submitted by Buyer, Buyer agrees to purchase such Products from Seller, and Seller agrees to sell and deliver to Buyer such Products at the Delivery Point and perform its
other obligations in this Agreement relating to such Products, all in accordance with the applicable Purchase Order and the terms and conditions of this Agreement. 

2.1.4 Cancellation of a Purchase Order; Rescheduling. Buyer may cancel a Purchase Order prior to the receipt of an Order
Acknowledgement. 
 2.1.5 Delivery Schedules. Delivery Schedules submitted by Buyer in connection with each Purchase Order it submits
pursuant to Section 2.1.2, and the PO Product Quantities contained in the Purchase Orders covering a Delivery Month, shall generally reflect the allocation requirements of this Section 2.1.5. For each Delivery Month,
approximately fifty percent (50%) of the aggregate quantity of Products that Buyer orders for delivery at the Destination Points in such Delivery Month under its Purchase Orders relating to such Delivery Month will be delivered to the
applicable Destination Points on Delivery Dates that fall between the first (1st) and the fifth (5th) day of the Delivery Month
(excluding Sundays and Federally-observed holidays). The other fifty percent (50%) will be delivered to the applicable Destination Points on Delivery Dates that fall between the fifteenth
(15th) and twentieth (20th) day of the Delivery Month (excluding Sundays and Federally-observed holidays). If a Sunday or
Federally-observed holiday falls within the applicable five (5) day period, such Sunday or holiday shall not serve to extend such period. Buyer may change Destination Points in a Delivery Schedule no later than fourteen (14) days before
the Scheduled Ship Dates for such Products as set forth in Seller’s Order Acknowledgement for such Purchase Order; provided, however, that the total quantities set forth in the Delivery Schedule for such Scheduled Ship Date may
not be changed without Seller’s written consent. Buyer may change the specific Delivery Dates within the five (5) day windows provided in this Section 2.1.5 only with the prior written consent of Seller (not to be unreasonably
withheld, conditioned or delayed).

month when a Delivery Month was the second and third calendar month in the Rolling Forecast Period; or (b) more than *** percent (***%) of the quantity that was set forth in the Rolling Forecast for such calendar month when such Delivery Month

 2.3 Annual Volumes. Buyer shall use commercially reasonable efforts, consistent with
past practice, to submit Purchase Orders which shall be binding for the purchase of an aggregate of *** (***) MW DC per year of Products consisting of Microinverters in anticipated quarterly volumes of approximately *** units. Seller agrees that
Purchase Orders submitted under the Original Agreement between January 1, 2014, and the Effective Date shall apply when determining if Buyer has satisfied its obligation under this Section 2.3. 

2.4 Modification of Product Specifications; New Products. Buyer acknowledges that Seller is continually striving to increase its
competitiveness in the marketplace by improving the Products and that doing so may require modifications to the Specifications for the Products, the development of new models of existing Products, or the development of entirely new products. 

2.4.1 Reports. Seller shall periodically provide Buyer with reports containing information relating to anticipated material
modifications in any current Specifications, the development of new product offerings that would be materially different than the Products, and/or any other material information that Seller reasonably believes would be relevant or useful to
Buyer’s evaluation with respect to continued purchase of Products; provided however, that in no event shall Seller provide a report to Buyer if in doing so it would be in violation of any applicable Law. 

2.4.2 Changes to Existing Product Specifications. Seller shall at all times use best efforts during the Term, maintain the ability to
manufacture Products meeting the Specifications set forth in Exhibit A (or the relevant Specifications as otherwise approved by Buyer pursuant to this Section 2.4). During the Term, Seller shall not, without Buyer’s prior
written consent, which will not be unreasonably withheld, substitute different products for the Products ordered by Buyer under any accepted Purchase Order; provided, however, Seller may substitute one or more Products ordered under a
Purchase Order with different Products without Buyer’s prior written consent if: (a) the Unit Price for the different Products is the same or less than as the Unit Price for the Products ordered by Buyer, the different Products are
backwards compatible in all respects, and the different Products have comparable or better Specifications (improved functionality) than the Products ordered by Buyer; or (b) Buyer has not ordered the Products for which Seller is substituting
the different Products in the six (6) months prior to the date of the applicable Purchase Order. Without limiting the foregoing, Seller shall use commercially reasonable efforts not to (i) discontinue the production of any Products (unless
Seller has a new product that is substantially similar to the Product), or (ii) make any modifications to the Specifications of Products to be sold to Buyer under this Agreement (unless such modifications improve the functionality of the
Product). Seller shall give Buyer reasonable written notice of any discontinuation or modification as described in clauses (i) and (ii) above. Buyer shall have the right, pursuant to Section 5.2, to reject any Product that
fails to conform to the Specifications or other requirements of this Agreement unless the new Specifications are agreed upon by the Parties or substitution was otherwise permitted by this Section 2.4.2. Once such material modification or
revision has received Buyer’s written approval, Seller shall cause the Products delivered and sold under Purchase Orders to comply with the modified Specification.

 2.4.3 New Products. Should Seller manufacture and/or offer to sell new products that are
similar to, or provide functionality or features similar to, the Products, Buyer shall have the right to purchase such products in addition to or in lieu of the Products. Prior to purchasing or selling such new product under a Purchase Order, the
Parties shall, pursuant to Section 18.8, amend Exhibit A to include the Product and pricing for such new product. Once Exhibit A is amended, such product shall become a “Product” for all purposes of this
Agreement. 
 2.5 No Stand-Alone Product Sales. Buyer is purchasing the Products for inclusion with Systems that it or its
Affiliates intend to sell to its customers, and Buyer is not in the business of reselling or distributing the Products on a stand-alone basis. Except for assignments pursuant to Section 18.4, or sales of the Products by Buyer to an
Affiliate or to a consumer host customer in each instance for purposes of inclusion in a System to be installed by such Affiliate, host customer, or their contractors at a Project, Buyer covenants that it will not re-sell or distribute Products on a
stand-alone basis to any other Person. 
 2.6 Branding. If Buyer uses the Enphase Trademarks in connection with its advertising,
promotion and marketing of Systems which include the Products and the Enlighten Service in the Territory and in related brochures and other materials, Buyer shall comply with Seller’s then current trademark usage policies and guidelines
available at http://enphase.com/legal, subject to the terms and conditions of this Agreement. Buyer shall not alter or remove from the Products or Seller’s Documentation any Enphase Trademark or Seller’s trade name, patent, copyright or
other proprietary notices, or other notices or markings, or add any other notices or markings to the Products or on Seller’s Documentation.

	***	Portions of this page have been omitted pursuant to a request for Confidential Treatment and filed separately with the Commission. 

  

8 

 The foregoing covenant shall not apply to Seller’s sales of products to ***. By execution of each Purchase
Order, Seller represents and warrants that the Unit Price for each Product being sold thereunder complies with the foregoing covenant. If Seller accepts a *** from any other such customer (other than ***), then (a) Seller shall promptly notify
Buyer of the ***, (b) the *** that are functionally equivalent to the products offered or sold to such other customer shall be *** for *** so that the *** by such other customer (the ***), and (c) for Products that Seller has already
purchased since the date on which the *** Buyer may *** that become due and owing under Invoices *** by such other customer and the applicable ***. The *** shall apply to all Products then subject to Purchase Orders and to all Products ***. Buyer
and Seller shall make an adjustment on the Purchase Order, Order Acknowledgement or pricing information (whichever method is most easily managed by each parties order processing teams) to document such change in Unit Price. Buyer shall have the
right to audit Seller’s books and records pursuant to Section 18.1 to confirm Seller’s compliance with this Section 3.1.3. 

3.2 Inclusions and Exclusions from Unit Prices. Except as otherwise set forth in this Section 3.2 or in Exhibit
A, the Unit Price includes all Taxes (other than U.S., State and local Taxes imposed on the sale or use of the Products), Product packaging, the Warranty, licensing fees, royalties or other similar charges of any and all kinds imposed with
respect to the provision of any Products or otherwise with respect to the transactions contemplated hereby, including any increases in any of the same during the term of this Agreement. The Unit Prices and Contract Amount do not include all:
(i) U.S. state and local Taxes imposed on the sale or use of the Products; and (ii) freight, transportation, shipping, transit insurance and similar costs and charges to ship the Products from the Delivery Point to the Destination Point.
Responsibility for payment of Taxes is described further in Section 3.9. 
 3.3 Invoices. Buyer agrees to pay the
Contract Amount to Seller in accordance with this Agreement. Upon the delivery of Products to the applicable Delivery Point set forth in the corresponding Purchase Order, Seller shall deliver an invoice to Buyer for that portion of the Purchase
Order allocable to such delivered Products, which invoice shall (a) specify the related Purchase Order number pursuant to which the delivery of Products was made, (b) list the model number as set forth on Exhibit A for the Products
delivered to the Delivery Point to which such invoice relates, and (c) set forth the applicable Unit Price, the Buyer’s Taxes and loading and shipping costs, under the related Purchase Order (each, an “Invoice”).
Buyer shall review the Invoice and if it determines that any of the information listed above is not set forth in the Invoice, then Buyer shall so notify Seller within five (5) Business Days. Seller’s failure to list any amounts due by
Buyer pursuant to this Agreement on an Invoice shall not be deemed a waiver of Seller’s right to collect such amounts from Buyer. Upon Buyer’s written request outlining the reasons for the request, Seller shall deliver to Buyer a waiver
and release of liens conditioned only on payment in such form as shall be appropriate and customary under applicable Law, signed by a duly authorized officer or representative of Seller. 

3.4 Payment. Payment is due on each Invoice, and shall be paid by Buyer, within *** (***) days following the date that Seller has
(a) delivered Products to the Delivery Point, and (b) delivered the corresponding correct Invoice to Buyer in accordance with Section 3.3 (the “Payment Date”). All payments by Buyer to Seller hereunder
shall be made by wire transfer of immediately available funds in accordance with Seller’s wire instructions set forth in Exhibit D. 

  

	***	Portions of this page have been omitted pursuant to a request for Confidential Treatment and filed separately with the Commission. 

  

9 

 Seller may update such wire information by prior written notice to Buyer and without amendment to
this Agreement. 
 3.5 Notice of Payment Disputes. On or before the Payment Date, Buyer may, in good faith, dispute such Invoice,
including as to whether the delivery of Products has been achieved or the Products meet the requirements of this Agreement and the related Purchase Order, by providing Seller with written notice identifying the basis for such dispute. Thereafter,
the payment of such disputed portions of the Invoice shall be deferred until such dispute has been resolved in accordance with the dispute resolution provisions in Article 13. Notwithstanding this Section 3.5, Buyer may not
dispute such Invoice on grounds that it is missing information required by Section 3.3 if Buyer did not notify Seller thereof within the five (5) Business Day period set forth in Section 3.3. 

3.6 Late Payments. Any undisputed amount not paid by Buyer to Seller when due shall accrue interest at the Late Payment Rate
beginning on the date that is five (5) Business Days after Buyer has received Seller’s written notice that such undisputed amount has not been paid. If there is a dispute about any amount Invoiced by Seller, the amount not in dispute shall
be promptly paid as described in this Article 3. Should any disputed amount be determined to have been properly payable, such amounts shall accrue interest at the Late Payment Rate from the date on which such payment was properly payable
until the date such payment is actually made. Late payments of any amounts payable by Seller hereunder shall be paid with interest at the Late Payment Rate from the date due until the date paid. 

3.7 Reconciliation. From time-to-time, as reasonably requested by Buyer, Seller shall submit to Buyer (a) a statement
summarizing and reconciling all previous invoices, payments relating to any Purchase Order, and (b) any additional information regarding the Products or Seller’s performance hereunder with respect to such Purchase Order. 

3.8 Payments Not Acceptance of Products. No payment made hereunder shall be considered or deemed to represent that Buyer has
inspected the Products or checked the quality or quantity thereof and shall not be deemed or construed as approval or acceptance of any Products, or as a waiver of any claim or right that Buyer may then or thereafter have, including any rejection or
warranty right. 
 3.9 Taxes. 

3.9.1 Minimization of Taxes. The Parties shall cooperate with each other to minimize the Taxes owed by each Party to the extent legally
permissible, including, without limitation, separately stating taxable charges on Invoices, supplying resale and exemption certificates, if applicable, and providing other information as reasonably requested. 

3.9.2 Seller Taxes. Other than the Buyer Taxes, Seller shall be responsible for and pay all other Taxes, as required by applicable Law,
incurred or payable in connection with Seller’s performance of its obligations under this Agreement or the Products, including, without limitation, payment of all: (a) Taxes based on or related to the income, receipts, capital or net worth
of Seller; (b) sales and use taxes assessed against Seller-owned, leased or rented 

  
 10 

 
equipment; and (c) all sales and use Tax or related items purchased by Seller in manufacturing the Products (collectively, the “Seller Taxes”). 

3.9.3 Buyer Taxes. Buyer shall, as required by applicable Law: (a) be responsible for and pay all Taxes based on or related to the
income, receipts, capital or net worth of Buyer; and (b) be responsible for paying to Seller under Invoices and pursuant to Section 3.9.4, all sales and use Taxes related to Buyer’s purchase of the Products (collectively, the
“Buyer Taxes”). 
 3.9.4 Seller’s Payment of Sales and Use Taxes. Buyer shall remain liable at all times
for all sales and use Taxes imposed upon the sale of the Products to Buyer (the “Sales and Use Taxes”). Provided that Seller has been able to collect the Sales and Use Taxes from Buyer, then Seller shall pay such Sales and
Use Taxes to the appropriate Governmental Authority on Buyer’s behalf. If Seller has actually collected Sales and Use Taxes in excess of the amounts required to be paid to a Governmental Authority and has not yet paid such Governmental
Authority, then Seller shall, within thirty (30) days of the discovery of such overpayment, refund to Buyer the difference between the amounts collected and the amounts due. If Seller has actually collected Sales and Use Taxes in excess of the
amounts required to be paid to a Governmental Authority and has paid such Governmental Authority, then Seller shall, within thirty (30) days of the receipt of a refund from such overpayment from the Governmental Authority, refund to Buyer the
difference between the amounts collected and the amounts due. If Seller has not actually collected Sales and Use Taxes in the amounts required to be paid to a Governmental Authority, then Buyer shall, within thirty (30) days of notice from
Seller, pay to Seller the difference between the amounts due and the amounts collected and Buyer shall remain liable for all interest and penalties assessed by the applicable Governmental Authority due to such failure or delinquency. 

ARTICLE 4 
 DELIVERY
SCHEDULING 
 4.1 Delivery Scheduling and Coordination.

4.1.1 Delivery and Scheduling. 

(a) Delivery. Seller shall deliver the Products under a Purchase Order to Buyer at the Delivery Point in accordance with
Section 5.1, the Scheduled Ship Dates set forth in the applicable Order Acknowledgement, and the scheduling provisions of this Section 4.1.1. Seller acknowledges and agrees that time is of the essence with respect to each
delivery of Products to the Delivery Point by the applicable Scheduled Ship Dates and that the Scheduled Ship Dates are established by Seller in each Order Acknowledgement so that, taking into account customary and reasonable transit times for
delivery to the applicable Destination Points and subject to the occurrence of Force Majeure Events, are scheduled such that the Delivery Dates for the Products will fall within the applicable five (5) day period of the applicable Delivery
Month pursuant to Section 2.1.5. 
 (b) Required Lead Time; Rush Orders. Unless consented to in writing by Seller, which
shall include, without limitation, an Order Acknowledgement, the Delivery 

  
 11 

 
Dates in a Delivery Schedule will be no less than sixty (60) days after the date that the applicable Purchase Order is sent by Buyer to Seller pursuant to Section 2.1.2
(“Required Lead Time”). If Buyer submits a Purchase Order with a Delivery Schedule that does not allow for the Required Lead Time (each, a “Rush Order”) and Seller accepts and issues an Order
Acknowledgement, Seller shall use commercially reasonable efforts to fill any such Rush Order. Notwithstanding anything to the contrary in this Agreement, Seller shall be under no obligation to accept a Rush Order and shall not be in breach of this
Agreement should it accept such Rush Order and fail to deliver the Products at the Delivery Point by the Scheduled Ship Date(s). 
 (c)
Deliveries Coordination. Seller and Buyer will each use their commercially reasonable efforts to coordinate logistics related to delivery of the Products at the Delivery Point and shipment of the Products to the Destination Point, including
through compliance with the procedures set forth in this Article 4 and Article 5. 
 4.1.2 Early Delivery.
Notwithstanding Section 4.1.1(a), (i) Seller may deliver agreed quantities of Products on dates prior to the Scheduled Ship Dates if agreed to in advance in writing by the Parties, and (ii) the Parties may otherwise agree in
writing on a delivery schedule for any Purchase Order different from the Delivery Schedule. Seller shall communicate any impact of such early delivery of the Products at the Delivery Point on the applicable Delivery Dates of such Products at their
Destination Point(s). Any change to the Scheduled Ship Dates that would cause the Delivery Date(s) to be outside of the five (5) day periods set forth in Section 2.1.5 shall require Buyer’s prior written consent. 

  
 12 

 4.2 Preferential Deliveries to Buyer. Consistent with the Most Favored Customer

DELIVERY, ACCEPTANCE AND REJECTION, TITLE AND RISK OF LOSS 

5.1 Delivery of Products, Shipment Protocol and Packaging.

5.1.1 Delivery Point. All Products purchased by Buyer and sold by Seller under Purchase Orders entered pursuant to this Agreement shall
be delivered by Seller to Buyer or its Carrier F.C.A. Seller’s Facility (INCOTERMS® 2010) (“Delivery Point”). The Delivery Point may not be changed in a Purchase
Order unless each Party indicates its agreement to such change by initialing such change in the Purchase Order, and Seller is not obligated to acknowledge a Purchase Order with a delivery point that is not the Delivery Point. 

5.1.2 Transportation Arrangements. Seller, at Buyer’s cost and expense, shall be responsible for making all transportation
arrangements with Carriers in order to ship such Product from the Delivery Point to the Destination Point, all in accordance with the applicable Delivery Schedule, the Shipment Protocol, and the other provisions of this Section 5.1. If
Buyer requires Seller to cancel its transportation arrangements with a Carrier in order to use a different Carrier, then Buyer shall be responsible for cancellation charges incurred by Seller. Seller shall employ the same level of care, diligence,
inquiry and effort to minimize transportation costs that it would use if Seller were paying the costs thereof and bore the risk of loss during shipment (but in no event less than reasonable care). All Carriers shall carry liability insurance
reasonably acceptable to Buyer, on an occurrence basis, with limits of no less than two million dollars ($2,000,000) per occurrence and aggregate, covering the loss of the Products while in transit or otherwise in the Carrier’s possession. 

(a) Carrier’s Inspection. Seller shall cause the Carrier to inspect the packaging of the Products prior to its loading of the
Products, and the Carrier shall have the authority to reject Products on behalf of Buyer if the packaging is damaged or fails to conform to Section 5.1.4. 

(b) Documents of Title. Seller shall provide the Carrier with a bill of lading, bill of sale or other document of title when the
Products are delivered to the Carrier at the Delivery Point. To the extent not included in the foregoing, Seller shall provide an itemized list of all Products delivered to a Carrier for each shipment (which may include multiple trucks) in order to
validate the quantity and type of Products delivered. 
 (c) Buyer’s Assumption of Transportation Arrangements. At any time
during the Term, upon written notice, Buyer may assume responsibility for transportation

(d) Cooperation with Claims. Seller shall provide reasonable cooperation and assistance in connection with any claims by Buyer against
any Carriers. 
 5.1.3 Notices. Seller shall provide written notice to Buyer and Carrier at least seven (7) days prior to each
delivery of Products to the Delivery Point, which notice shall include an itemized list of Products being delivered. Seller shall notify Buyer, or cause the Carrier to notify Buyer, promptly following the delivery of each shipment of Products to a
Carrier for shipment to Buyer. Such notice shall include the anticipated Delivery Dates. Buyer shall, and shall cause its Carrier to, keep Buyer reasonably informed regarding any changes to such anticipated Delivery Dates. 

5.1.4 Packaging. Seller shall package, mark and handle all of the Products in accordance with prudent commercial practices in the United
States solar industry and Seller’s standard practices. All packaging (inner and outer cartons) shall identify the contents by manufacturing model number and serial number for each Product contained in such packaging, and all labeling shall be
bar-coded. 
 5.1.5 Importer of Record. For all purposes hereunder and under applicable Law, Seller shall be the “importer of
record” with respect to all Products delivered in the Territory. 
 5.1.6 Shipment Protocols. All deliveries of Products shall be
made by Seller within the five (5) day time periods set forth in Section 2.1.5 and in accordance with the shipment protocols set forth in this Section 5.1.6 (the “Shipment Protocol”) or as
otherwise agreed by the Parties in writing. 
 (a) Flow of Delivery Trucks at the Delivery Point. Seller shall coordinate its
Carriers so that they comply with the following requirements, unless such requirements are waived by Buyer’s Representative in writing and in advance: 

(i) Deliveries of Products to the Destination Point shall only occur on Business Days between the hours of 8:00 a.m. to 4:00 p.m., provided
that deliveries at the Destination Point may occur later than 4:00 p.m. with reasonable prior notice to Buyer; and 
 (ii) No containers
owned by Seller or the Carrier shall be left at the Destination Point. 
 (b) Type of Delivery Truck. A Seller’s Representative
and a Buyer’s Representative will, in advance of delivery of the Products to the Delivery Point and in connection with Seller arranging transportation pursuant to Section 5.1.2, coordinate regarding the type of delivery truck to be
used and any logistical limitations thereon based on the Destination Point. 

  
 14 

 (c) Deliveries to Storage Facilities. Without limiting anything else herein or in this
Agreement, if the Destination Point is a storage facility, such deliveries shall comply with the requirements of the relevant storage facility. 

5.2 Rejection of Products; Deemed Acceptance.

5.2.1 Rejection of Products. 

(a) Inspection. Buyer shall use commercially reasonable efforts to inspect the Products within a reasonable period of time following
arrival of the Products at the Destination Point. 
 (b) Rejection. Notwithstanding Section 5.2.1(a) or anything to the
contrary in this Agreement or pursuant to applicable Laws (including, without limitation, New York Uniform Commercial Code § 2-602(1) or any state law equivalent to Section 2-602(1) of the Uniform Commercial Code), Buyer or its
representatives may, by notice to Seller pursuant to Section 5.2.1(c), reject any non-conforming Product or shipments of Products up to the earlier of: (a) fifteen (15) days following the discovery of any Product that
does not conform with the applicable Specification, the applicable Purchase Order, the applicable Warranty, or any other requirement set forth in this Agreement; (b) commencement of installation of the Product; or (c) sixty (60) days
following the Delivery Date. Without limiting the generality of the foregoing, Buyer (or the Carrier on Buyer’s behalf) may reject any Product if, after visual inspection of the Product or its packaging at the time that such Product is received
by the Carrier, it appears that any portion thereof or the containers in which such items were shipped have been damaged. If Buyer rejects any Product, Buyer shall have the right to take the following actions, at Buyer’s option: (i) retain
the non-conforming Products in whole or in part with an appropriate adjustment in the price as mutually agreed upon by the Parties, in which case, Buyer shall, by its retention of the defective Products, waive all claims or liabilities related to,
or resulting from, the failure of the Products to conform to the applicable Warranty, or (ii) require Seller to replace the rejected Product at Seller’s sole cost and expense (including shipping and transportation costs to the nominated
Destination Point) and promptly deliver the replacement Product to Buyer within thirty (30) days after receiving Buyer’s written notice of rejection. 

(c) Notice of Rejection. Buyer’s notice of rejection shall include (i) a detailed description of the reason(s) for the
rejection, (ii) if applicable, of the damage or defect to the Product, (iii) the location of the rejected Product, and (iv) the option selected by Buyer under clauses (i) or (ii) of Section 5.2.1(b). 

(d) Responsibilities Following Rejection; Impact of Rejection. Upon any notice of rejection of any Product, Buyer shall have no further
responsibility for the rejected Product other than those obligations set forth in the following sections of the New York Uniform Commercial Code §§ 2-602(2), 2-603, and 2-604, or any other state law equivalent to Sections 2-602(2), 2-603,
and 2-604 of the Uniform Commercial Code, Unless Buyer elected to retain the non-conforming Products pursuant to Section 5.2.1(b)(i), Seller shall promptly arrange for the removal of such rejected Product at Seller’s sole cost and
expense. Title to the Product shall pass from Buyer to Seller at the time that Seller or Seller’s agent picks-up the rejected Product from the Destination Point, and the fact that title is held by Buyer between notice of rejection and its

  
 15 

 
passage Seller at such time shall not be deemed a violation by Buyer of New York Uniform Commercial Code § 2-602(2)(a) or any other state law equivalent to Section 2-602(2)(a) of the
Uniform Commercial Code. 
 (e) Disputes Regarding Buyer’s Right to Reject. If Seller believes that Buyer’s rejection of a
Product was wrongful, then Seller shall notify Buyer within fourteen (14) days of the date that the rejected Product was recovered by Seller or its agent from Buyer. Any dispute shall be resolved pursuant to Article 13. Should Buyer
wrongfully reject a Product, Seller’s rights with respect to such Product (but not the entire Agreement or other shipments of Products), shall be those set forth in New York Uniform Commercial Code § 2-703(d) or (e) or the equivalent
state law incorporating 2-703(d) and (e) of the Uniform Commercial Code. 
 5.2.2 Acceptance. Any Products not rejected in
accordance with Section 5.2.1 shall be deemed accepted by Buyer; provided, that such deemed acceptance shall not affect any right or remedy available pursuant to the Warranty applicable to the Product regardless of whether such
right or remedy is exercised by Buyer or by any assignee or transferee permitted thereunder. Once accepted, any defects discovered in a Product shall be resolved pursuant to the terms and conditions of the applicable Warranty, and Buyer shall follow
Seller’s standard “RMA Procedures” for returning any non-conforming Products using Seller’s. Delivery of a Product to the Carrier at the Delivery Point, or receipt by Buyer of a Product at the Destination Point,
shall in no event be construed as Buyer’s acceptance of the Product. 
 5.3 Transfer and Warranty of Title. Title to each
Product shall pass from Seller to Buyer at the Delivery Point when such Products have been loaded on the Carrier’s means of transport. Seller warrants good title to all Products furnished hereunder, and Seller warrants that title and ownership
thereto shall pass to and vest in Buyer as described in this Section 5.3 free and clear of any and all Liens. For the avoidance of doubt, transfer of title to Products hereunder shall not affect Buyer’s rights or Seller’s
obligations as set forth in other provisions of this Agreement (including Article 4, Article 7 and Article 8). 

5.4 No Liens.
 5.4.1 No
Seller Liens; Removal. Seller shall not permit or suffer to exist any Lien, including a Lien of any Person claiming by, through or under Seller, its subcontractors, vendors or any Affiliate thereof, upon the Products, any Project incorporating
such Products, or other property of Buyer or any Person to whom Buyer has assigned or otherwise transferred Products (each, a “Seller Lien”). If any such Lien is imposed or asserted, Seller shall promptly (but in any event
within such period as to avoid a default by Buyer under any applicable financing agreement or contracts entered into by Buyer, in each case as notified by Buyer to Seller) pay or discharge and discharge of record (including by recording a bond in
the amount of at least 120% of the amount of such Seller Lien not paid or discharged to the extent permitted by and in accordance with applicable Law) any such Seller Lien or other charges which, if unpaid, might be or become a Seller Lien. 

5.4.2 Buyer Right to Remove. Upon the failure of Seller to timely discharge or cause to be released any Seller Lien as required under
Section 5.4.1, Buyer may, but shall not 

  
 16 

 
be obligated to, pay, discharge or obtain a surety bond for such Seller Lien and, upon such payment, discharge or posting of surety bond, shall be entitled to reimbursement from Seller of the
amount equal to one-hundred fifty percent (150%) thereof together with all out-of-pocket expenses reasonably incurred by Buyer in connection with such payment, discharge or posting upon the submission of an invoice thereof to Seller setting
forth all such amounts. Seller shall pay any such invoice from Buyer within thirty (30) Business Days from the date of the invoice. 

5.4.3 Security Interests Created by Operation of Law. Seller shall be entitled to a Lien against the Products by operation of Law to
secure payment for the Products, to the greatest extent permitted by applicable Law; provided however, that any such Lien with respect to one Product shall not apply to any other Product, and payment in full for one Product shall serve to release
such Lien therein. There shall be no cross-collateralization of the Products. 
 5.5 Risk of Loss. Subject to
Section 5.2.1, care, custody and control of the Products, and risk of loss to the Products, shall transfer from Seller to Buyer at the Delivery Point when such Products have been loaded on the Carrier’s means of transport. 

5.6 Serial Defects, Recalls. If at any time during the Term, Seller (a) receives *** regarding Products from Buyer arising out
*** relating to *** of the Products that are under Seller’s warranty sold to Buyer ***, or (b) recalls any Products sold to Buyer, then Buyer shall notify Seller. Upon such notification, the Parties shall meet to discuss the underlying
issues related to problem that resulted in either (a) or (b). If Buyer believes that Seller is not addressing the issue in a manner that is reasonable to Buyer’s position, Buyer may, upon written notice and without being in breach or
default of its obligations under this Agreement or any Purchase Order: (i) suspend issuances of Purchase Orders for such Product; (ii) direct Seller to suspend deliveries of such Products to Carriers at the Delivery Point;
(iii) reject shipments of such Products at the Destination Points and cause the Carriers to return the Products to Seller at Buyer’s expense but without further liability to Seller under this Agreement; or (iv) notwithstanding
Section 5.2, reject any such Products then in storage at Buyer’s facility or any contracted storage facility and return such Products to Seller at Buyer’s expense but without further liability to Seller under this Agreement.
The foregoing remedies are not exclusive, and Buyer may elect to apply one remedy with respect to certain Products and a different remedy with respect to other Products. Seller shall perform or caused to be performed a root cause analysis with
respect to the extensive component failures and provide Buyer with a written report explaining the likely causes of the serial defect and how Seller intends to address the matter. Buyer shall not be obligated to resume performance under this
Agreement until Seller has supplied evidence reasonably satisfactory to Buyer to demonstrate the defect has been addressed with respect to manufacturing additional Products. Seller shall, at its sole cost and expense and without the need for Buyer
to make a further claim under the Warranty, address the serial defect in each Product sold to Buyer under this Agreement. Seller may address the serial defect through repair, replacement, retrofit, refund or another remedy that Seller reasonably
deems appropriate and technically feasible under its Warranty, provided that such solution addresses the defect. Buyer and Seller shall cooperate in good faith to effectuate the remedy elected by Seller. Buyer shall resume performance under this
Agreement so long as Seller’s efforts to correct the serial defect in Products that have been delivered under this Agreement are ongoing.

 ARTICLE 6 

INSPECTIONS AND TECHNICAL ASSISTANCE 

6.1 Buyer Inspections and Testing.

6.1.1 Manufacturing Facility Inspections. In the event that Buyer experiences an unreasonable amount of failures of the Products, then
Buyer (or its representatives) may (i) inspect Seller’s Manufacturing Facility, including inspection of the production of the Products at Seller’s Manufacturing Facility, in accordance with this Section 6.1 or
(ii) perform an inspection of the Products and Seller’s manufacturing and packaging procedures of those Products at Seller’s Manufacturing Facility or Seller’s Facility, either (i) or (ii) to be at a time that is

Any representative of Buyer shall be obligated to sign a non-disclosure agreement in favor of Seller. 
 6.1.2 Costs and Expenses. Any
inspection and quality control tests undertaken by Buyer or its representative shall (a) be undertaken at Buyer’s cost and expense, and (b) be carried out in accordance with all applicable Laws and in such a manner as will not
unreasonably interfere with the operation of Seller’s Manufacturing Facility or Seller’s Facility, as applicable. 
 6.1.3
Discovery of Defects; Corrective Actions. In the event that any inspection or testing by Buyer indicates that any of the Products designated for a shipment are defective and/or do not comply with the Specifications, the applicable Purchase
Order, the applicable Warranty, or any other requirement set forth herein, Buyer shall notify Seller of such defect or non-compliance, and Seller shall implement all necessary actions to ensure that the Products to be shipped to Buyer in accordance
with this Agreement and the Purchase Orders comply with the Specifications, the applicable Purchase Order, the applicable Warranty, or such other applicable requirement set forth herein. 

6.1.4 Inspections Not Waiver. Nothing in this Section 6.1 relating to any inspections or quality control tests undertaken
with respect to Products, including any required replacement of Products that do not pass such inspection or testing, shall operate to relieve Seller’s obligations to deliver the Products on a timely basis in accordance with
Article 4 or to limit Buyer’s termination rights pursuant to Article 10. 

  
 18 

 6.2 Seller Technical Assistance.

6.2.1 From time-to-time during the Term, Buyer may, in its discretion, send to Seller (a) requests for clarifications regarding the
requirements of the Product Installation Manual and (b) technical drawings and other information relating to Buyer’s proposed design or procedures for the installation of the Products into a Project, with the request that Seller confirm
that installation in accordance with such technical drawings or other information is consistent with the Product Installation Manual and therefore would not, on its own, constitute the basis for an exclusion under the applicable Warranty. Seller
shall promptly respond in writing to any such request. The failure of Buyer to make any requests for clarifications or to send technical drawings or other information to Seller pursuant to this Section 6.2.1 shall not operate to limit
Seller’s obligations under this Agreement or any Purchase Order, including with respect to the applicable Warranty. 
 6.2.2 To the
extent not otherwise required of Seller under the terms of the applicable Warranty hereunder, Seller will use commercially reasonable efforts to provide Buyer with technical assistance and support with respect to the Products for the Warranty Period
of the Products, including notifying Buyer of any (a) newly discovered material design defects or manufacturing defects affecting large quantities of products similar or identical to the Products and any proposed corrective approach; and
(b) any software upgrades or other improvements; provided, however, except as specified in Section 5.6, the foregoing shall not obligate Seller to preemptively correct any potential defect before it arises under the
Warranty or make such improvements or software upgrades available to Buyer without compensation. 
 ARTICLE 7 

WARRANTIES 
 7.1
Warranty. Seller shall provide the Warranties with respect to the Products supplied pursuant to this Agreement delivered hereunder; provided, that nothing in the Warranties (including, without limitation, the disclaimer) shall be
read or deemed to limit Seller’s obligations or Buyer’s rights as expressly set forth in this Agreement. The “Warranty Period for Microinverters purchased under a Purchase Order and Seller’s standard limited
warranty period is twenty (20) years from the Delivery Date of the applicable Microinverter. Should Buyer desire to extend the Warranty Period for one or more Microinverters from twenty (20) years to twenty-five (25) years from the
Delivery Date thereof, Buyer may do so by submitting to Seller a report on a quarterly basis containing the serial numbers of Microinverters to be covered by a twenty-five (25) year Warranty Period; provided however, that Buyer may only make
such an election during the first twelve (12) months from the Delivery Date. After receiving the report, Seller shall invoice Buyer for the amount of the additional five (5) years as set forth in Exhibit A (as amended from time to
time). Payment terms on such invoices are net *** (***) days. The standard Warranty Period for Envoys purchased under the Agreement is two (2) years from the date of that the Envoy is installed at the first end user location. Seller may make
changes to the Warranties at any time during the Term, provided such changes do not have a material or adverse effect on the warranty rights of Buyer or any transferee of such Warranties.

19 

 7.2 Warranty Transferable. The Warranties shall be freely transferable by Buyer,
without notice to or consent of Seller, to any subsequent owner of the Products at the original site of installation. Notwithstanding any such transfer, Buyer shall be a joint beneficiary of the Warranties supplied hereunder and shall have the same
rights as any transferee, on behalf of such transferee, to make claims and obtain service, recoveries and other remedies under the Warranties with respect to the applicable Products; provided, that under no circumstance shall both Buyer and
the applicable transferee be entitled to make claims and obtain service, recoveries and other remedies with respect to the same claim, defect or similar issue with respect to such Products. 

7.3 Warranty Upgrades. If Seller materially changes the terms and conditions of its standard warranty that is applicable to
products that are the same as the Products in a manner that is more favorable to its customers, upon Buyer’s request, the Parties shall amend this Agreement to substitute such warranty (but such changes shall apply only for Products purchased
after such material changes are made) for that set forth in Exhibit G, as applicable; provided, however, the foregoing obligation of Seller to enter into an amendment shall not apply to extension of the warranty periods, but
Seller agrees to negotiate in good faith with Buyer with respect to any such extensions.

limitation, product liability claims), losses, damages, expenses and liability (including court costs and reasonable attorneys’ fees) (collectively, the “Losses”) brought against or incurred by any Buyer Indemnitee
arising out of or relating to this Agreement or any Purchase Order to the extent such Losses are caused by or are the result of (a) any breach of this Agreement by Seller or its successors and assigns (collectively, the
“Seller-Related Persons”), (b) breach of the Warranties, including manufacturing defects and design defects, (c) the negligence or willful misconduct of the Seller-Related Persons, (d) any product liability

 8.2 Seller’s Hazardous Materials Indemnity. Seller shall defend, indemnify
and hold harmless each Buyer Indemnitee from and against all claims, losses, fines, costs, penalties or expenses imposed upon any of them (including court costs and reasonable attorneys’ fees), regardless of whether or not such claims, losses,
fines, costs, penalties or expenses arise from or are incurred by third parties, that they may incur or suffer by reason of: (a) the existence in or any release from a Product of any Hazardous Material; (b) any enforcement or compliance
proceeding commenced by or in the name of any Governmental Authority arising from or related to the existence in or any release from a Product of any Hazardous Material; and (c) any action reasonably necessary to abate, remediate or prevent a
violation or threatened violation of any 

  
 20 

 
Applicable Law by any Buyer Indemnity with respect to the existence in or any release from a Product of any Hazardous Material. 

8.3 Seller’s Intellectual Property Rights Indemnity. Seller shall defend, indemnify and hold harmless the Buyer Indemnitees
from (a) any breach of Seller’s representations, warranties, covenants and obligations set forth in Section 16.1 and (b) any claim of any third party that any Product as furnished by Seller to Buyer under this Agreement
infringes any Intellectual Property Rights of such third party. Without limiting the generality of the foregoing, Seller shall, at Seller’s option and Seller’s sole cost and expense, either (i) procure for Buyer the right to continue
using the infringing Product or (ii) modify or replace the infringing Product so that it becomes non-infringing, in either case in a manner and time period that does not unreasonably interfere with Buyer’s activities or operations. If in
connection with any such claim the continued use of any Product is forbidden by any court of competent jurisdiction, and neither of the foregoing remedies under clauses (i) or (ii) are available, and provided that in no event may Seller
take any action which adversely affects Buyer’s continued use and enjoyment of the Products without the prior written consent of Buyer, Seller shall refund to Buyer the amounts paid by Buyer to Seller for the infringing Products, without
reduction or offset, and shall provide any commercially reasonable assistance requested by Buyer in procuring a suitable replacement for the infringing Product.

penalties or expenses arise from or are incurred by third parties.

 8.7 Notice of Claim. A Buyer Indemnitee or Seller Indemnitee (each, an
“Indemnified Party”) shall, promptly after the receipt of notice of the commencement of any legal action or of any claims against such Indemnified Party in respect of which indemnification may be sought pursuant to the
provisions of this Article 8, notify Seller or Buyer, as the case may be (each, an “Indemnifying Party”) in writing thereof, provided that the failure of an Indemnified Party promptly to provide any such notice
shall only reduce the liability of the Indemnifying Party by the amount of any damages attributable to the failure of the Indemnified Party to give such notice in such manner. In case any such claim or legal action shall be made or brought against
an Indemnified Party and such Indemnified Party shall notify the Indemnifying Party thereof, the Indemnifying Party may, or if so requested by the Indemnified Party shall, assume the defense thereof and after notice from the Indemnifying Party to
the Indemnified Party of its election to assume the defense thereof with legal counsel reasonably satisfactory to the Indemnified Party, the Indemnifying Party will not be liable to the Indemnified Party under this Article 8 for any
legal fees and expenses subsequently incurred by such Indemnified Party in connection with the defense thereof. If the Indemnifying Party does not assume the defense of any such claim or legal action, then the Indemnifying Party shall remain liable
to such Indemnified Party for any legal fees and expenses incurred by such Indemnified Party in connection with the defense thereof. No Indemnified Party shall settle any indemnified claim over which the Indemnifying Party has not been afforded the
opportunity to assume the defense. The Indemnifying Party shall control the settlement of all claims over which it has assumed the defense; provided, that the Indemnifying Party shall not conclude any settlement which requires any action or
forbearance from action by an Indemnified Party, or any payment by an Indemnified Party, without the prior approval of the Indemnified Party. The Indemnified Party shall provide reasonable assistance to the Indemnifying Party as reasonably requested
by the Indemnifying Party, at the Indemnifying Party’s sole cost and expense, in connection with such legal action or claim. For claims over which the Indemnifying Party has assumed the defense, the Indemnified Party shall have the right to
participate in and be represented by counsel of its own choice and at its own expense. 
 8.8 Term of
Indemnities. Notwithstanding any other provision in this Agreement to the contrary, the indemnification obligations and rights set forth in this Article 8 shall survive the expiration or other termination of this Agreement, and
Buyer’s acceptance of any Products shall not be construed to relieve Seller of any obligation under this Article 8. 
 8.9

Agreement. Seller shall provide to Buyer an insurance certificate meeting the requirements of Exhibit H by the earlier of (i) ten (10) days after the Effective Date and (ii) within five (5) days of the date of the first
Purchase Order delivered by Buyer hereunder. 
 8.10 Setoff. In the event that Seller owes to Buyer any amounts and only in the
event of Seller’s breach of Sections 10.1.2(a) or 10.1.2(b), then Buyer may set off such amounts (including any awarded attorney’s fees and costs) against any amounts then due and owing (or that become due and owing) to
Seller; provided, however, that Buyer has given Seller at least five (5) Business Days’ notice of its intent to set off pursuant to the terms of this Section 8.10.

 ARTICLE 9 

COMPLIANCE WITH LAWS AND STANDARDS AND CODES 

9.1 Generally. Seller shall at all times comply, and shall ensure that the Products when delivered comply, with all Laws and
Standards and Codes applicable to the design, manufacture and intended use of the Products, the delivery thereof, and the performance by Seller of its other obligations hereunder. 

9.2 Changes in Law.
 9.2.1
Notices of Changes in Laws or Standards and Codes. In the event that any change in any applicable Law or Standards and Codes applicable to the Products or their manufacturing are enacted or otherwise approved after the Effective Date
and such change requires or makes advisable any modifications in the design, manufacturing, delivery, installation, operation or other use of the Products, Buyer or Seller, as the case may be, shall reasonably promptly notify the other thereof in
writing upon its discovery of such change in Laws or Standards and Codes. 
 9.2.2 Modification of Scheduled Ship Dates; Buyer’s
Rights. If any such modification is required by any such Law or Standards and Codes and Seller has received notice thereof, then the Parties agree to resolve how Seller shall make any such modification, if practicable, at its sole cost
and expense, subject to Section 9.2.3. If Seller fails to modify the Products to comply with applicable Laws or Standards and Codes in effect as of the applicable Scheduled Ship Date, or fails to give written assurances that such
Products (when delivered at the Delivery Point) will comply with the then-effective Laws or Standards and Codes, then Buyer shall have the right to cancel the applicable Purchase Order. Should Seller tender Products at the Delivery Point that fail
to comply with the then-effective Laws or Standards and Codes, Buyer shall have the right to reject such non-conforming Products pursuant to Section 5.2. 

9.2.3 Modification of Unit Prices. In the event that a change in any Law or Standards and Codes requires substantial
modifications to a Product’s design, materials or its manufacturing process (operational expenditures, but not capital expenditures) then the Parties shall promptly meet and work to resolve the cost of any such modifications and how it might
impact the overall price for the Product. Any adjustment in the Unit Price pursuant to this Section 9.2.3 shall in all cases be reflected in an amendment to Exhibit A pursuant to Section 18.8 (which, subject to
Buyer’s right to terminate below, the Parties shall promptly execute following resolution of any disagreements) and the revised Unit Prices shall only apply to Purchase Orders issued by Buyer after the date of such amendment. Should the Parties
fail to agree on an amendment, or if Buyer determines it no longer desires to purchase the Product given the changes in the Product Specifications or manufacturing process, Buyer may, at Buyer’s discretion, either (a) terminate this
Agreement by notice to Seller, or (b) elect by written notice to Seller to continue with this Agreement, and in such case, (i) Buyer shall be relieved of its obligation to use commercially reasonable efforts to purchase certain quantities
of Products as set forth in Section 2.3, and to purchase minimum quantities as set forth in the then-applicable Rolling Forecasts pursuant to Sections 2.2.1 and 2.2.2, (ii) thereafter, Buyer may (but is not required

more Purchase Orders affected by such Event of Default, (b) seek specific performance of the defaulting Party’s obligations hereunder, (c) suspend performance under the Agreement or any Purchase Order until the defaulting Party cures
such default, provided that Seller shall not suspend its obligations to perform Warranty service or to provide the Services set forth in Section 17.1 (unless, with respect to Section 17.1, Buyer’s Event of Default is its
failure to pay for the Enlighten service and such suspension occurs consistent with Section 17.1); or (d) seek any other legal or equitable remedy available to such non-defaulting Party under applicable Laws. In addition, in the
event of a Seller’s Event of Default, Buyer may exercise its rights pursuant to Section 16.3. For clarity, for a Seller Event of Default set forth in Section 10.1.2(h), in addition to termination of this Agreement and
any other right or remedy available to Buyer under applicable Law or equity, the Parties agree that the amounts payable under Section 3.1.3 shall promptly be paid by Seller to Buyer. 

10.2.2 Any termination for an Event of Default shall be without prejudice to any other right or remedy the non-defaulting Party may have under
this Agreement or at Law or in equity (including the remedy of contract damages), and no such remedy shall be exclusive of any other remedy except as otherwise expressly set forth herein. 

10.3 Termination for Force Majeure. If a Force Majeure Event affects the performance of the claiming Party for ninety
(90) consecutive days, the non-claiming Party may terminate this Agreement or an affected Purchase Order upon not less than thirty (30) days prior written notice to such Party. 

10.4 Limited Continuation at Buyer’s Election. If this Agreement is terminated by Buyer due a default of Seller pursuant to
Sections 10.1.2(a), (c) or (d), then Buyer shall have the option, in its sole discretion, to continue to submit Purchase Orders for Products (and Seller shall have the obligation to continue to accept such Purchase Orders)
pursuant to Section 2.1 wherein the Delivery Schedule for all such Purchase Orders provides for delivery to the Delivery Point on or before the first anniversary of the effective date of any such termination. If Buyer so-elects to
continue to purchase Products then, notwithstanding such termination, this Agreement, except for Sections 3.1.3, 7.3, 9.2, 17.2, 18.1, shall continue in full force and effect solely with respect to purchases of
Products during such period, and any other provision applicable to other Products or periods shall survive such termination or expiration only to the extent expressly set forth herein. During such period, the Unit Price shall remain the same as on
the date immediately prior to the day of termination by Buyer. 
 ARTICLE 11

ILLEGAL OR UNLAWFUL ACTS, (c) AMOUNTS DUE TO SELLER FOR UNPAID INVOICES, OR (d) SELLER’S WARRANTY OBLIGATIONS SET FORTH IN Article 7 AND EXHIBIT G. THE LIMITS OF LIABILITY SET FORTH IN THIS AGREEMENT SHALL NOT BE
REDUCED BY THE AMOUNT OF INSURANCE PROCEEDS AVAILABLE TO THE INDEMNIFIED PARTY. 
 11.4 No Limitation on Remedies. Except where
this Agreement states that the applicable remedy set forth herein is the sole or exclusive remedy (or words of similar import) for such event, the rights and remedies of the Parties with respect to this Agreement in relation to such event are in
addition to, and shall not be read or deemed a limitation on, those rights and remedies that may be available to a Party at law or in equity.

 ARTICLE 13 

DISPUTE RESOLUTION 
 13.1
Dispute Resolution, Consent to Jurisdiction and Equitable Remedies.
 13.1.1 If a dispute arises between Seller and Buyer in any way
arising out of or relating to this Agreement, the disputing Party shall promptly provide written notice to the other Party of the dispute (a “Notice of Dispute”). Within five (5) Business Days of the receipt of such
Notice of Dispute, the Parties shall meet to negotiate in good faith to resolve the dispute quickly and with minimal costs to the Parties. If the Parties shall have failed to resolve any such dispute within thirty (30) days after receipt of the
Notice of Dispute, either Party may bring suit in the United States District Court for the District of New York, or if such court does not have jurisdiction over such dispute, in the District Court of the State of New York, in each case located in
New York City, which courts shall have exclusive jurisdiction with respect to all disputes arising out of or relating to this Agreement or any Purchase Order. By execution and delivery of this Agreement, each of the Parties hereby accepts the
exclusive jurisdiction of the United States District Court for the District of New York, or if such court does not have jurisdiction over such dispute, in the District Court of the State of New York, in each case located in New York City. 

13.1.2 Each Party irrevocably agrees to be bound by any final judgment (subject to any appeal available pursuant to applicable Law) of the
applicable court determined in accordance with Section 13.1.1. Each Party irrevocably waives, to the fullest extent permitted by Law, any claim that any such suit brought in any such court has been brought in an inconvenient forum. Each
of the Parties hereto knowingly, voluntarily, intentionally and irrevocably waives any right it may now or hereafter have to a trial by jury in any litigation based herein, or arising out of, under, or in respect of this Agreement, or any course of
conduct, course of dealing, statements (whether oral or written) or actions of the Parties hereto. 
 13.1.3 Notwithstanding any provision in
this Agreement, the Parties understand and agree that any breach or threatened breach of this Agreement by Seller may result in irreparable injury to Buyer, that any remedy available to Buyer at Law in relation to such breach or threatened breach
would be an inadequate remedy for such breach or threatened breach and that, in addition to any other remedies Buyer has under this Agreement or any Purchase Order or under Law for such breach or threatened breach, Buyer shall be entitled at any
time to seek to enforce the specific performance of this Agreement and the applicable Purchase Orders by Seller through injunctive relief, without the necessity of proving actual damages or posting a bond and without limitation of the right to
recover such damages. 
 13.2 Continued Performance During Dispute Resolution. During the pendency of any dispute, the Parties
shall continue to timely and diligently perform any obligation under this 

  
 30 

 
Agreement that is not the subject of a dispute; provided, however, if Buyer fails to timely make payment on an invoice without disputing such invoice pursuant to
Section 3.5, Seller may reject any Purchase Orders issued by Buyer until Buyer pays such overdue amounts (including amounts owed for Enlighten pursuant to Section 17.1.1) and any interest thereon in full. Without limiting the
foregoing, Seller shall continue performing its warranty obligations and its obligations under Article 17. 
 ARTICLE 14

 FORCE MAJEURE 

14.1 Force Majeure Events. Performance under this Agreement shall be excused due to, and a Party shall not be liable for or deemed
in breach of this Agreement because of, any failure or omission to carry out or observe its obligations under this Agreement, to the extent that such performance is rendered impossible or delayed by fire, flood, act of God or the public enemy, act
of a Governmental Authority (other than in respect of the failure of a Party to comply with applicable Law), national or regional labor difficulties, riot, perils of the sea, or any other extraordinary event where the failure to perform or the delay
is beyond the reasonable control of, and could not have been reasonably foreseen by, the nonperforming Party; provided that such event is not caused by or attributable to the negligence or fault of, or breach of its obligations hereunder by,
such Party, and could not have been avoided by prudent commercial practices (any such event, a “Force Majeure Event”). Force Majeure Events shall not include: (a) mechanical or equipment failures (except to the extent
any such failure is itself caused by a Force Majeure Event); (b) delays in customs clearance (except to the extent any such delay is itself caused by a Force Majeure Event); (c) any delays or other problems associated with the issuance,
suspension, renewal, administration or withdrawal of, or any other problem directly or indirectly relating to, any Governmental Approval or the applications therefor where such delays or problems are within the affected Party’s reasonable
control; (d) labor strikes or other labor difficulties that are not of a general and widespread nature or are specific to the affected Party’s personnel or facilities; (e) any weather condition unless of a catastrophic nature or
listed above; (f) lack of financial resources, cost increases in commodities or labor, or other economic conditions; and (g) failure of raw or finished material supply, unless such failure was itself the result of a Force Majeure Event.

 14.2 Notice of Force Majeure Events. As a condition to claiming a Force Majeure Event, the claiming Party shall promptly give
the other Party a written notice describing the particulars of the Force Majeure Event of the occurrence of any such Force Majeure Event, including an estimate of the expected duration and the probable impact of the Force Majeure Event on the
performance of such Party’s obligations hereunder. The Parties agree to use reasonable efforts to notify each other of potential Force Majeure Events and update each other on developments regarding potential Force Majeure Events. The Party
claiming the Force Majeure Event shall have a continuing obligation to deliver to the other Party regular updated reports supporting its claim regarding a Force Majeure Event promptly after such information is available to such Party and until such
time as the Force Majeure Event is no longer in effect. 
 14.3 Mitigation. The impact of the Force Majeure Event on a
Party’s performance shall be of no greater scope and no longer duration than is reasonably required by such event. The Party claiming a Force Majeure Event shall have a duty to alleviate and mitigate the cause

  
 31 

 
and effect, including duration, costs and Delivery Schedule impacts, in each case arising from such Force Majeure Event, and to resume performance of its affected obligations under this Agreement
and the affected Purchase Orders promptly after being able to do so. The burden of proof with respect to a Force Majeure Event shall be on the Party claiming the same. 

ARTICLE 15 

CONFIDENTIALITY 
 15.1

any of Buyer’s Confidential Information, except as expressly set forth in this Agreement or any Purchase Order and otherwise solely to the extent necessary for Seller’s performance of its obligations hereunder. Seller shall deliver the
Buyer’s Confidential Information, including all copies thereof, to Buyer upon its request. 
 (c) Without limiting the generality of
Section 15.2.1(a): (i) as between Buyer and Seller, Buyer shall have exclusive ownership of all information, data, and documents relating to the Projects in which any of the Products are installed; and (ii) in no event shall
Buyer be deprived of its rights to the energy production data, customer data, or any other information (“Data”) that may be stored in or accessible by any Products with respect to Systems owned or operated by Buyer;
provided, however, that Seller shall have the right to use Data pursuant to the terms of Section 16.4, but only if and to the extent that (A) the Data is aggregated and (B) the Data does not identify Buyer or any
customer of Buyer. Seller hereby disclaims any and all other right, title or interest in and to all such Data. 
 15.2.2 Confidentiality
of Agreement. Each Party shall keep the terms of this Agreement and all Purchase Orders confidential, unless (a) the other Party consents in writing to such disclosure in advance, (b) disclosure is required by lawful subpoena of a
Governmental Authority or pursuant to rules or regulations of a Governmental Authority, including, without limitation, the Securities and Exchange Commission or similar state securities authority, or (c) otherwise provided in this
Section 15.2.2. If a Party is compelled by Law to disclose the terms of this Agreement or a Purchase Order, except in the case of disclosure required by the Securities 

  
 32 

 
and Exchange Commission or state securities authority, the Parties shall cooperate in seeking a protective order or other order limiting disclosure. If a protective order or a similar order
limiting disclosure is not obtained, the compelled Party shall furnish only that portion of the terms of this Agreement that, upon the advice of its legal counsel, it is legally required to disclose. Without the prior consent of the other Party,
(i) each Party may disclose the terms of this Agreement to its employees, partners, auditors, consultants, accountants, financial institutions or advisors, investment partners, Financing Parties, attorneys, and other third party advisors,
provided such disclosure is on a “need-to-know” basis and such Persons are legally bound by a contractual or professional obligation to keep this Agreement confidential and to not further disclose the terms of this Agreement, and
(ii) the Parties may file this Agreement with the Securities and Exchange Commission, provided that such Party filing this Agreement shall work with the other Party to determine what information (such as pricing and other proprietary business
information) will be the subject of “CTR.” 
 15.2.3 Publications and Announcements. No Party shall make a public
announcement or issue a press release about this Agreement, the transactions set forth herein, the terms and conditions of this Agreement, or the Party’s relationship without the prior written consent of the other Party. Each Party shall
coordinate with the other Party with respect to, and provide advance copies to such other Party for review of, the text of any proposed announcement or publication that may include any non-public information concerning this Agreement or the
activities or obligations of any Party hereunder prior to the dissemination thereof to the public or to any Person other than such announcing Party’s employees, contractors, subcontractors, representatives, agents or Affiliates, in each case,
who agree in writing to keep such information confidential. The non-announcing Party shall deliver written notice to the announcing Party of any objections to the proposed announcement or publication within a reasonable period of time after
receiving the advance copy of the proposed announcement; provided, however, the non-announcing Party’s failure to notify the announcing Party of any objections shall not be construed as a waiver of the covenant set forth in the first sentence
of this Section 15.2.3. The Parties shall work in good faith to resolve any objections. Subject to the foregoing, the Parties shall issue a mutually agreeable, joint press release promptly after execution of this Agreement announcing the
Parties entry into a long term supply agreement. This Section 15.2.3 shall be subject to Section 2.6, and Buyer shall be permitted to use, and Seller hereby consents to Buyer’s use of, Seller’s name and the Enphase
Trademarks consistent with the Seller’s then current trademark usage policies or to generally announce to potential customers the use of Seller’s Products when marketing a System.

20-YEAR LIMITED MICROINVERTER WARRANTY 
  

 
 

 
 ENPHASE ENERGY M215 MICROINVERTER 

20-YEAR LIMITED WARRANTY FOR 

INSTALLATIONS IN NORTH AMERICA 

Enphase Energy, Inc. (“Enphase”) has developed a highly reliable microinverter, designated as the M215 Series
(“Microinverter”), that is designed to withstand normal operating conditions when used for its originally intended purpose in compliance with the Enphase User Manual made available with the originally shipped system. The
Enphase limited warranty (“Limited Warranty”) covers defects in workmanship and materials of the Microinverter (“Defective Product”) for a period of twenty (20) years from the date of original
purchase of such Microinverter at point of sale to the system owner (the “Warranty Holder”) at the originally-installed end user location (the “Warranty Period”). All Microinverters shall, at the time
of delivery by Enphase to the original purchaser, will be new and unused and comply with all applicable laws, standards and codes in effect at such time. 

During the Warranty Period, the Limited Warranty is transferable to a different owner (“Transferee”) as long as the Microinverter
remains installed at the originally-installed end user location (“Original Location”). 
 During the Warranty Period, if Enphase
establishes, through inspection, the existence of a defect that is covered by the Limited Warranty, Enphase will at its option, either (1) repair or replace the Defective Product free of charge, or (2) issue a credit or refund to the
Warranty Holder of the system in an amount up to its actual value at the time the Warranty Holder notifies Enphase of the defect, as determined by Enphase. 

If Enphase elects to repair or replace the Defective Product, Enphase will, at its option, use new and/or reconditioned parts in repairing or replacing the
Defective Product. Enphase reserves the right to use parts or products of original or improved design in the repair or replacement of Defective Product. If Enphase repairs or replaces a Defective Product, the Limited Warranty continues on the
repaired or replacement Microinverter for the remainder of the original Warranty Period or ninety (90) days from the date of Enphase’s return shipment of the repaired or replacement product, whichever is later. The Limited Warranty covers
a replacement unit to replace the Defective Product, but does not include labor costs related to (1) un-installing the Defective Product or (ii) if applicable, re-installing a repaired or replacement product. To the extent applicable, the
Limited Warranty also covers the costs of returning the Defective Product via Enphase’s RMA policy and procedure described further below, as well as shipping a repaired or replacement product from Enphase, via a non-expedited freight carrier
selected by Enphase, to locations specified by the Warranty Holder of the Defective Product. The Limited Warranty does not cover, and Enphase will not be responsible for, shipping damage or damage caused by mishandling by the freight carrier and any
such damage is the responsibility of the freight carrier. 
 Enphase Microinverters are designed to withstand normal operating conditions and typical wear
and tear when used for their original intent and in compliance with the installation and operating instructions supplied with the Microinverter. The Limited Warranty does not apply to, and Enphase will not be responsible for, any defect in or damage
to any Microinverter: (1) that has been misused, neglected, tampered with, altered, or otherwise 

  
 Exhibit G-1 

 
damaged, either internally or externally; (2) that has been improperly installed, operated, handled or used, including use under conditions for which the Microinverter was not designed, use
in an unsuitable environment, or use in a manner contrary to the Enphase User Manual (as supplied to the Warranty Holder) or applicable laws or regulations; (3) that has been subjected to fire, water, generalized corrosion, biological
infestations, acts of nature, or input voltage that creates operating conditions beyond the maximum or minimum limits listed in the Microinverter specifications, including high input voltage from generators or lightning strikes; (4) that has
been subjected to incidental or consequential damage caused by defects of other components of the solar system; or (5) if the original identification markings (including trademark or serial number) of such Microinverter have been defaced,
altered, or removed. The Limited Warranty does not cover costs related to the removal, installation or troubleshooting of the Warranty Holder’s electrical systems. The Limited Warranty does not extend beyond the original cost of the Enphase
Microinverter. 
 To obtain repair or replacement service, credit or refund (as applicable) under this Limited Warranty, the Warranty Holder must comply
with the Return Merchandise Authorization Number (RMA) policy and procedure http://www.enphase.com/rma. 
 Enphase expressly reserves the right to
novate or assign its rights and obligations under this Limited Warranty to a third party with the demonstrated expertise and requisite resources needed to effectively discharge the obligations hereunder. 

THE LIMITED WARRANTY IS THE SOLE AND EXCLUSIVE WARRANTY GIVEN BY ENPHASE AND, WHERE PERMITTED BY LAW, IS MADE EXPRESSLY IN LIEU OF ALL OTHER WARRANTIES,
EXPRESS OR IMPLIED, STATUTORY OR OTHERWISE, INCLUDING, WITHOUT LIMITATION, WARRANTIES OF TITLE, QUALITY, MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE OR NON-INFRINGEMENT OR WARRANTIES AS TO THE ACCURACY, SUFFICIENCY OR SUITABILITY OF ANY
TECHNICAL OR OTHER INFORMATION PROVIDED IN MANUALS OR OTHER DOCUMENTATION. IN NO EVENT WILL ENPHASE BE LIABLE FOR ANY SPECIAL, DIRECT, INDIRECT, INCIDENTAL OR CONSEQUENTIAL DAMAGES, LOSSES, COSTS OR EXPENSES HOWEVER ARISING, WHETHER IN CONTRACT OR
TORT, INCLUDING WITHOUT LIMITATION ANY ECONOMIC LOSSES OF ANY KIND, ANY LOSS OR DAMAGE TO PROPERTY, OR ANY PERSONAL INJURY. 
 To the extent any implied
warranties are required under applicable law to apply to the Microinverter, such implied warranties shall be limited in duration to the Warranty Period, to the extent permitted by applicable law. Some regions do not allow limitations or exclusions
on implied warranties or on the duration of an implied warranty or on the limitation or exclusion of incidental or consequential damages, so the above limitation(s) or exclusion(s) may not apply. This Limited Warranty gives the Warranty Holder
specific legal rights, and the Warranty Holder may have other rights that may vary from region to region.
