Its difficult answering your questions when you are posting same problem in two different forums.
We need to know what type inverter you have one of the larger ones or a small 600 watt in a compartment feeding your TV and one outlet near passenger seat and up in the cabinet in front of passenger seat.
If its the 600 watt inverter it has a GFI on the inverter that needs to be reset.
You can not use heavy amperage items in the passenger area outlet or you will just keep tripping the GFI on inverter.
Your converter is locate in your shore line power bay near transfer switch.
GFI's would be in bathrooms, kitchen area.
Check the bathrome area cabinets maybe another load center in there.
and Owners Guide.
If you have the larger inverter you have a 30 amp c/b box near the inverter, wiring diagram on section 15 page 17 Owners Guide.
