Using GFCI outlets without a bonded ground?

Do GFCI outlets work correctly on an inverter with an unbonded ground?

I have not tried a GFCI on an unbounded ground, but it might partially work. A modern GFCI outlet is watching two things:
1) Differential current between Hot and Neutral of 7ma or more. This should continue to work.
2) There are corner cases where there could be current on ground without a differential current on hot-netural. Through tricks with harmonic ocilation, the modern GFCI is able to detect current on the ground wire when there is no differential current. I suspect this function may not work or possibly trip if there is not bond.

Could you tell us more about why you are asking?

On my Samlex 2000w 24v PS inverter the built in main dual receptacle is a GFCI outlet.

on an inverter there could be a transient imbalance during a switchover that could cause a sensitive gfi to trigger.
I had one gfi outlet on a 120 line from an aims inverter (this model bonds the neutral to ground during switchover) that I had to take out as it had 50% chance to trip during a switchover.
The nature of a switchover is that for 10-15ms, there is definitely an "imbalance" hehe
