The thing to keep in mind with a VFD is that they are almost always for driving 3-phase motors. I'm not aware of them for driving single phase motors, but heck, everything seems to exist somewhere.

Check out a new fuel cell:

EFOY

as long as you don't have high draws, this can keep batteries charged automatically, noiselessly, no genset.

Impressive new German tech.

So if your batteries can power all your needs, and you know how many A/H you need daily, this is a great solution.
