I have installed a Victron Multiplus 12/3000/120-16/230V inverter in my widebeam boat, AC is fed from a diesel generator. With the inverter in the on position AC is fed through an RCD to the consumer unit supplying the boat’s domestic circuits. This works fine no problems.
With the generator running and the inverter on postion, it trips over to charge the batteries; bulk,absorption and then float. Or with the generator running and the inverter in charger only, it goes through the bulk, absorption and float.
The problem is when the generator is running, the slightest AC load trips the RCD. I understand that an unbanlanced load would trip the RCD, but this does not happen when the inverter is fed from the battery bank, and in the on postion. Neither does it happen when the generator is running and fed through the RCD to the consumer unit.
Any help as what to do would be greatly appreciated. TIA.
