I was going to add this to a existing post, but decided better here.
I have installed a Phoenix 12/375 on a boat.
DC in is polarity correct and 12.8v as measured with DMM. DC ground is a earth wiring which goes to the engine, also connected to the engine is the bonding wires and negative DC.
When I power on the inverter the status light indicates operation is normal.
When I plug AC devices into the inverter they function normally.
Measured with a DMM between neutral and phase is 230v AC - normal.
However measured between earth and neutral is 115v AC (exactly half of 230v AC). I do not think this is normal, can anyone please advise?
Thanks
