Need Help Wiring Inverter.

I crammed two relays in one box. If doing this today I would have the smaller TS by KISAE.

Looks nice I guess if I have to buy another one I will get one of those. For now I'm just going to run all of the outlets off a single 15 amp breaker. The Hot wire from the output side of thbe breaker is wired into the ATS.

Anyways I got everything hooked up and I'm still having some issues. I found every time I plugged in shore power (from the house) my GFCI would trip on the outlet it was plugged into.

As it is now, I have the ground buss in the ATS connected to the ground buss in the Main panel (via the ground wire in the romex). I found removing the ground wire coming out of the inverter plug solved the problem with tripping the house gfci.

I also have all the neutrals connected together. So when when the inverter is on and the ATS is running off inverter power, but the rest of the trailer is running on shore/generator power (I have the breaker turned off that powers the ATS), then the neutral would be shared for the inverter and shore power since they end up connected together. Is this a problem? I'm thinking this is what is actually causing the issue, maybe isolating the neutrals would solve the problem and allow me to plug back in the ground wire? I'm thinking the issue is due to the inverter potentially tying neutral to ground internally?


Also, I have not grounded the inverter to the trailer via the extra ground terminal.
