PV Connection
CAUTION:
Before connecting to PV modules, please install separately a DC circuit breaker between inverter and
PV modules.
WARNING!
All wiring must be performed by a qualified personnel.
WARNING!
It’ very important for system safety and efficient operation to use appropriate cable for PV module
connection. To reduce risk of injury, please use the proper recommended cable size as below.

PV Module Selection:
When selecting proper PV modules, please be sure to consider below parameters:
1. Open circuit Voltage (Voc) of PV modules not exceeds max. PV array open circuit voltage of inverter.
2. Open circuit Voltage (Voc) of PV modules should be higher than min. battery voltage.
Please follow below steps to implement PV module connection:
1. Remove insulation sleeve 10 mm for positive and negative conductors.
Check correct polarity of connection cable from PV modules and PV input connectors. Then, connect
positive pole (+) of connection cable to positive pole (+) of PV input connector. Connect negative pole (-)
of connection cable to negative pole (-) of PV input connector.
2. Make sure the wires are securely connected.
Final Assembly
After connecting all wiring, please put bottom cover back by screwing four screws as shown below.
