Residential frig trips inverter GFI

We have a 2019 3721RL. All has been well until our last trip when we found out that when we disconnected from shore power at home and the 2000 watt inverter took over automatically the GFI would trip after a couple of minutes. Only the frig is running off the inverter during during transport. I did try running the frig connected to an extension cord and it run as it should. I then changed the inverter to a 3000w Rengry inverter and it tripped the breaker. My thought is the problem is from the frig wiring going to the inverter. Not an easy test as I can't pull the frig out because Keystone put the island in the way. Anyone have any similar problems or any ideas ?

I went through this issue on my fridge install. Inverter would run for a time, then the gfi on my 1000watt inverter would trip. I ran an extension cord from my inverter directly to the fridge and had the same issue. I solved my issue by replacing the gfi in the inverter with a standard outlet and it has been flawless since. This is one of those reasons why it isn't recommended to run fridges and freezers from household gfi devices. Minute current differences between the hot and neutral legs are what cause gfi trips.

jcurtis934 is correct Refrigerators should not be on GFI outlets, it states that in the manual for Samsung. I replaced my GFI in the inverter and it has worked fine since. Several posts talk about this issue.
