Hi Pete,
I haven't tried that, but I'm sure it'd be happier than my hacked VFD - my lathe can only run on 415v 3-phase, so VFD has the incoming AC rectifier modded to a voltage-doubler so it thinks it has 480V coming in instead of 240, and single-phase instead of the 3-phase it really wants so it puts more of a strain on the bus reservoir cap's - possibly the worst it could be expected to handle and hasn't died yet...
Your generated 3-phase will probably have one leg higher than the others, but not substantially enough to harm the rectifier or cap's, and all three phases will contribute to the VFD bus power, should be fine?
