Kalakoa,
You can install a gfci on an ungrounded circuit and it will work fine. Hence the little tag that comes with them that says "no equipment ground." The phantom load from a gfci is very small or set your inverter to search with a setting so that it will not find the gfci. The $10 ones work fine on solar. And finally, I think (but did not search for the reference) all power cords on a construction site must be gfci protected. Buy a cord with one installed. Bottom line, a gfci can save your life.
I worked on a site once where the cement mixer would trip the gfci. The general's solution? Bypass the the gfci and tell the crew not to touch the mixer so you would not get a shock.
