This is what I did.

12v + > 200amp breaker > Battery
12v - > battery

110 Green > Ground Bus Bar in Circuit Box
110 White > White Bus Bar in Circuit Box
110 Black > Added 15amp Breaker



This is the inverter in question

Should I just put the lines from the inverter on a 110v 20a DPST for the white and black to isolate it when plugged into shore power so I don't have to open the bench and unplug it every time?

I don't think you can do that in the main box. You have to have switch, transfer box or something to keep the inverter separate from the main power.

BTW #4 wire ampacity is closer to 160 amps in free air and 136 in a confined space.
Did the instructions really say #4?

You need a DPDT 30a switch. Main cord to one side, inverter on the other, common to the main breaker and buses. Otherwise when the inverter is on the cord prongs will be hot. Switching on the inverter and switching off the main is not to code without a lockout device.

Leviton makes such a switch but I think you are better with a regular RV autotransfer switch.

Yep, I think this is his problem. Also by powering the panel with the inverter, the on board CONVERTER is also being powered and it will try to charge the battery WITH the battery unless it is disconnected somehow.

I also agree #4 is fused to high at 200 amps. It should be fused less than the wire rating (150 amps).

Wondering if Help is putting cart before the horse? Op states he has isolated the new add from existing circuits, so why won't shore power stay engaged? Could be a true ground fault or I've changed a few faulty GFCI in RV and homes.

X2, like I said.

When I use the inverter, I make sure only the breaker I put in for it and the GFCI Outlet breakers are on. Converter, air con, water heater, etc are all off.

what you are doing will work...BUT you must use the double pole switch. You cannot have the shore power and inverter tied together at all. This means your shore and inverter - hot AND neutral must be separate. use a double pole, double throw switch. inverter on one set of inputs, shore power on the other set of inputs, and the rv panel on the common.

Instead of having to remove the 30amp romex from the box, could I just put a DPST inbetween the inverter and the box, that way its interrupted completely?
