4.3.3 AC Connecon
The AC terminal contains “GRID” and “BACK-UP”, GRID for load, and BACK-UP for emergency load.
Before connecting, a separate AC breaker between individual inverter and AC input power is necessary. This will ensure the inverter be securely disconnected during maintenance and fully protected from current of AC input. An extra AC breaker is needed for On-Grid connection to be isolated from grid when necessary. Below are requirements for the On-Grid AC-breaker.
