Is it necessary to install a breaker on the forth inverter AC side?

1. It is recommended to add a circuit breaker or fuse on the AC side, whose specification is more than 1.25 times of rated AC output current.

2. 70~240 mm² copper wire is recommended. If aluminum wire is needed, please check the requirements of the wire and then purchase by yourself. 3. Use copper terminal for copper wire, use copper aluminum terminal for aluminum wire, not aluminum terminal directly.
