Overload Cutout

Multiplus 12/3000/120-50 230v fitted to my yacht a year ago is shutting down showing overload. On shorepower it ran for 7 hours then cut out, after resetting it ran for 20mins and now 20secs before cutting out. On inverter mode it cuts out within seconds each time.

I only have 16A shore supply and the controller is set at 16A.

I've progressively isolated everything on the output side till I reached the unit and then disconnected the 230v input side, leaving just the batteries connected and it still cuts out on overload.

There is buzzing sound which gets louder before cutting out.

There is no sign of liquid ingress.

Has anybody else had similar problems with this unit?

Thanks

Alan
