Hi
Just purchased motorhome with solar,not an expert but the wiring on the inverter doesn’t look right,
There is a wire from the neutral pin on the plug on the AC side connected to the negative on the DC side is this correct (see pics)IMG_1001.jpeg
 
Power company neutral wire is connected to ground so that your ground fault circuit breaker has a reference to trip. Ground on a campervan is the chassis and negative so, it's not wrong. The same happens to generators.
 
On my inverter, this is done internally halfway so, there is no "neutral". Both output lines are "live", measuring 115V to ground and 230V between them. Ground fault circuit breaker still works since it's referenced.
