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.
AC Input Connection
CAUTION:
Before connecting to AC power source, please install a separate AC circuit breaker between
inverter and AC utility. It’s recommended to use 25A/2P/230V/4500A circuit breaker.
Recommended terminal types:
CAUTION: Important
Before making AC input connection, be sure to do the following actions to prevent human injury or machine
damage.
1. It’s required to turn off circuit breaker.
2. Make sure to connect single-phase AC input to the L & N input connectors in inverter.
