The first symptom of my problem is that my 700W Cook Power Microwave trips my 1.5kW/3kW Ames PSW Inverter. An amp clamp reveals that the microwave draws about 8 to 10 amps. The trip occurs each time the magnetron kicks on.
When I plug a GFCI circuit tester into the output jack of the inverter it indicates Open Ground. My (-) of the 24VDC is tied to trailer chassis and my AC neutral is not bonded to the chassis but will have a bond provided by the shore power panel. I have an isolation relay that will allow shore power/generator to power all AC circuits when external power is applied and the inverter powers AC when no external power is available. AC grounds are all tied together and bonded to the trailer chassis and are not switched by the shore power relay. The inverter chassis is tied to trailer chassis.
Am I doing this wrong or is there a problem in the inverter?
