Grid (AC) Connection
5-1. Preparation
Before connecting to AC utility, please install a
separate
circuit breaker between inverter and
AC utility. This will ensure the inverter can be securely disconnected under load.
NOTE1:
Although this inverter is equipped with a fuse (F1 point on PCB, 250VAC/20A), it’s
still necessary to install a separate circuit breaker for safety consideration. Please use
250VAC/20A circuit breaker.
NOTE2:
If you want to add a manual RCMU, it shall be type B.
WARNING!
It's very important for system safety and efficient operation to use appropriate
cable for grid connection. To reduce risk of injury, please use the proper recommended cable
size as below.
