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. batteryvoltage.
Solar Charging Mode

PV Array MPPT Voltage Range
60~145Vdc
Please follow below steps to implement PV module connection:
1.
Remove insulation sleeve 10 mm for positive and negativeconductors.
2.
Check correct polarity of connection cable from PV modules and PV input
connectors. Then, connect positive pole (+) of connection cable topositive
pole (+) of PV input connector. Connect negative pole (-) of connection
cable to negative pole (-) of PV inputconnector.
3.
Make sure the wires are securely connected.
