Multiple inverters cannot share one circuit breaker.
Never connect a load between the inverter and the circuit breaker.
Residual Current Monitoring Device
With an integrated universal current-sensitive residual current monitoring unit
inside, the inverter will disconnect immediately from the mains power once a
fault current with a value exceeding the limit is detected.
However if an external residual current device (RCD) is mandatory, the switch
must be triggered at a residual current of 300 mA or higher.
