Must use five core outdoor cable, the recommend AC cable and Residual current
breaker (RCD) as below table:
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.

. In case to have a properly
anti-islanding function, please choose the high-quality PV cable and ensure the
power loss is less than 1%. Meanwhile, the inverter AC side to grid connection
point must less than 100m. the relation between cable length, cross section area
