Application Note – Installing SolarEdge Home Hub three phase inverters
and SolarEdge Home 48V Batteries in Commercial Sites
Revision History
Version 1.0 (December 2023)

Introduction
This document provides design principles for SolarEdge commercial PV sites consisting of SolarEdge Commercial inverter(s) andSolarEdge Home Hub inverter(s) - Three Phase, connected to SolarEdge Home Battery 48V.
NOTE
For detailed installation and design guidelines for SolarEdge products described in this document, refer toSolarEdge Knowledge Center.

Home Hub Inverter - Design Considerations
Only a Home Hub Three Phase Inverter can be the Leader inverter on site.
The Leader Home Hub Three Phase Inverter MUST connect to the SolarEdge Monitoring Platform.
The Leader Home Hub Three Phase Inverter MUST connect to at least one battery module (see compatible battery table above).
All Follower SolarEdge Home Hub Three Phase inverters may be connected to a compatible battery(s).
All Home Hub Three Phase Inverters may be connected to PV strings with a single compatible power optimizer per PV module(1:1).

Three Phase Commercial Inverter - Design Consideration
When adding a Home Hub Inverter to an existing commercial site, the commercial Leader inverter, at the existing site, MUST beconfigured as a Follower Inverter.

Supported Interfaces and Control Features
Site Export Limitation Control
SolarEdge Firefighter Gateway (FFG)
SolarEdge Commercial Gateway (CCG) - when used for communication and connection of environmental sensors.
Power Reduction Interface (PRI) – for inverter power control

Limitations and Exclusions
SolarEdge Smart Home Devices are not supported (such as: SolarEdge EV Charger, SolarEdge Hot Water Controller, SolarEdge
Home Load Controller and Home Smart Switch).
Backup operation and SolarEdge Backup Interface (BUI) are not supported2System Description

Description

LeaderInverter

Only SolarEdge Home Hub Inverter – Three Phase, Part Numbers: SExxK-RWB48Bxxxx, SExxK-ILB48Bxxxx, SExxKILBZ48Bxxxx can be used as a Leader Inverter.
The Leader inverter MUST connect to:
A compatible battery
SolarEdge Monitoring Platform
A supported Export/Import meter (See Supported Meters below)

FollowerInverters

Up to 2 SolarEdge Home Hub Inverters – Three Phase, Part Numbers: SExxK-RWB48Bxxxx, SExxK-ILB48Bxxxx,
SExxK-ILBZ48Bxxxx (See Datasheet, Guide).
And a combinaiton of the below commercial inverter options:
Up to 3 inverters in any combinaiton of Three Phase Commercial Inverters, PN: SExxK-xxxxIxxxx (See Datasheet,Guide). and Three Phase Inverters with Synergy Technology, PN: SExxxK-xxxxIxxxx (See Datasheet, Guide)

Batteries

The Leader inverter MUST connect to at least one compatible battery model: BAT-05K48 (See Datasheet, Guide).
Each Home Hub Inverter – Three Phase can connect to between 1-5 battery modules.
The Follower Commercial Inverters cannot connect to SolarEdge batteries.

SupportedMeters

SE-MTR-3Y-400V-A or SE-WND-3Y400-MB-K2 (For UK, G100 compliant meter).
Note – The SolarEdge Home Inline meter is not supported in this configuration

Maximumsite power

Maximum site production is the sum of all inverters' nameplates

Maximumpower
when no PVpower

When the PV strings are not producing power, the maximum discharged power depends on the total number ofHome Hub Inverters – Three Phase and the number of connected battery modules.
Each Home Hub Inverter – Three Phase can provide the following charge / discharge power:
When a single battery module is connected to the Inverter, the power is (charge/discharge) 2625W / 4096W
When two or more battery modules are connected to the Inverter, the power is (charge/discharge) 5000W /5000W

The following figure shows a diagram with the maximum number of inverters supported by a storage commercial site.
