The electrical connection should be realized as follows:
(A) Router (B) Battery (C) PV string
(D) Inverter (E) AC circuit breaker (F) Smart Energy Meter
(G) Grid (H) Backup loads (I) Monitoring device
Install an AC circuit breaker on the backup side. Otherwise, an electrical short cir-
cuit may occur, causing damage to the inverter.
Ensure that AC output cables are firmly connected. Failing to do so may cause in-
verter malfunction or damage to its AC connectors.
Make sure not to switch the phase order (L1-L3) which may cause malfunction.
