Does it work OK on Shore power?
Has it always worked while on inverter?
Is inverter new to the setup or factory installed?
Brand/model of inverter?
Did you plug shore cord into inverter outlet?
Is the inverter 120V output hard wired to your 120V system?
If you installed inverter and GFCI has never worked with the inverter then the issue most likely IS the inverter.
Most cheap inverters are designed to use a floating neutral when compared to the safety ground and will have about 60V AC on the neutral and aprox 60V on the Hot..
GFCIs don't like that and will rebel..
And most cheap inverters tend to not like the neutral connected to safety ground or the battery negative terminals which are connected to the frame of your RV..
The frame of your RV is also bonded to the safety ground of your 120V AC electrical system..
