My experience has been that nuisance tripping of AFCI and GFCI devices
can be caused by excessive THD.

I’ve seen GFCI have all sorts of weird issues. Not enough data to
put the blame on the inverter.
I’d try different big load or move the device to a different
outlet and see what it does.
Good luck

I called EG4 tech support about this question. They said to use a
commercial grade, 20 A GFCI receptacle.
My question is: "isn't a 15 and 20 A GFCI electronically the same?
Isn't the only difference in the faceplate?"
Thank you,
Drake

A commercial grade, Hubble GFCI receptacle is nuisance tripping on
an EG4 XP6000 inverter. It holds fine on an LED light bulb. Under a
heavy load (PVC Heater), it trips after a minute or so.
Is there a GFCI receptacle brand that works better with the XP6000
inverter?
Thank you,

The followup is that I changed the GFCI to a 20 A rated version, and it
held the load.
