Waterproof and Dustproof Solar Charge Controller

User's Manual Ver.1.02E

IP68
1. Introduction
Thank you for purchasing “SolarAmp BG” solar charge controller. Thismanual contains important safety, installation and operating instructions
for “SolarAmp BG” solar charge controller in order to prevent the users
from any damage. Make sure to read all of the instructions and cautions in
the manual before beginning installation.

2. Product Overview“SolarAmp BG” is very compact design and very simple to use, which has
full electronic protections, waterproof and dustproof.

3. Features
・Waterproof and dustproof (IP68)
NOTE: This does not guarantee no damage, no breakdown, or waterproof and dust
proof performance in all conditions.

・3-stage Charging (Bulk, Absorption, Float)
・Discharged Battery Recovery
・Full Electronic Protections
High / Low Voltage Protection, Over Discharge Protection, Over Load Protection,
High Temperature Protection, Reverse Polarity Protection,
Load Short Circuit Protection, Surge Protection

・Current Regulation Caused High Temperature・Positive Earth Ground・Status LED Indications
State of Charging, High / Low Voltage, Over Load, High Temperature

4. Precaution
・Cover the PV panel (Photovoltaic panel: Solar panel) with cloth not togenerate electricity during installation.
・It is recommended to install an external fuses (less than rated current)
between controller and battery, controller and load.
・Connect battery to earth ground if necessary (positive earth ground). If
you need negative earth ground, connect only one terminal (battery orPV panel or load terminal) to the earth ground.
・Do not connect device which has large input capacitance such as DCAC inverter to the load terminal.
・Do not use PV panel or Load of which specification is out of the ratings.
The PV panel Voc should never exceed ”Max. Input Voltage” of the controller.
The PV panel Isc should never exceed ”Max. Input Current” of the controller.
The Peak current of load should never exceed ”Max. Load Current” of the controller.

・Charging will start when PV panel voltage exceeds battery voltage.
・Reverse Polarity Protection and Over Load Protection is not effective inevery possible condition, thus please take care when wiring andconfirm the specifications of PV panel and battery and load.

5. Safety Information
5-1: DO NOT short circuit (For allterminals)

5-2: Explosion hazard

5-3: Keep out of direct sunlight

5-4: Positive earth ground5-5: DO NOT reverse polarity
connection (For all terminals)

6. Connection
