My 2022 CB31 charger/inverter stopped working a few weeks ago, so my boat electrician removed it and installed a new 3000 watt Victron charger/inverter, which works on generator and shore power for a few seconds and cuts out, and continues to cycle in and out every few seconds. The inverter works just fine off the batteries, however, I am not using of course for the microwave and AC appliances, only to charge my phone. Batteries are fully charged off the alternator. My electrician thinks that my AC neutral wiring is not to ABYC standards, showed me a schematic by Blue Sea that is supposedly the correct wiring method, and wants to change it tomorrow to attempt to correct the issue. Has anyone heard of this before my electrician goes ahead and makes some changes to the factory wiring?
