Warning
To ensure the inverter can be safely disconnected with load, must install a
separate single-phase circuit-breaker or other load disconnection unit for
each inverter.
Note: The inverter is equipped with integrated RCM (Residual current
operated monitor) and RCD (Residual current protective device). The rated
residual current of the circuit breaker must be over 300mA when the AC
circuit breaker with RCM function selected.
Notice
When using inverter comply with VDE-AR-N 4105:
The total capacity of PV-inverter system cannot exceed 13.8KVA, and the
adjustment function of inverter's displacement power factor must comply
with VDE-AR-N 4105.
When using inverter comply with CEI 0-21:
The total capacity of PV-inverter is more than 3KW and less than or equal
6KW, the inverter's displacement power factor is adjustable between 0.95
leading to 0.95 lagging, and do not need external SPI.
The total capacity of PV-inverter is more than 6KW, the inverter's
displacement power factor is adjustable between 0.9 leading to 0.9
lagging, meanwhile need external SPI.
Install an independent two-pole circuit breaker at the output side of the inverter for
protection, the recommended AC circuit-breaker specifications are as follows:
