Table 5-1 The recommend AC cable and Residual current breaker (RCB)
The inverter does not require an external residual-current device when in
operation.
If one is required under local regulations, SOFAR recommends a type A or B RCD
with sensitivity of 100mA or higher.
Where local electricity code requires an RCD with a lower leakage ratings, the
discharge current might result in nuisance tripping of the external RCD. Sofar
recommends the following measure in selecting an external RCD to avoid nuisance
tripping:
1: Selecting appropriate RCD.
2: Configure the trip current of inverter internal RCD to a lower value that the trip
current of the external RCD.
