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.
Solar Charging Mode
INVERTER MODEL
4KW/5KW/6KW/8KW/10KW/12KW
Max. PV Array Open Circuit Voltage
250Vdc
PV Array MPPT Voltage Range
60~245Vdc
Min. battery voltage for PV charge
34Vdc
Please follow below steps to implement PV module connection:
1.
Remove insulation sleeve 10 mm for positive and negative conductors.
2.
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.
3.
Make sure the wires are securely connected.
