A lot of the larger UPS are kind of pricey, and you won't find many that
will do split phase.
I got a steal on Ebay for $500. I had to set up a switch to break my
320V pack in the middle, and a small DPST contactor to parallel the two
half packs at 160V. That works out to 12 batteries at 13.3V each and
works fine. If you have a ~400V pack (typical of a lot production cars)
that could be split to 200V which should work well with a UPS designed
for 16 12V batteries (192V).

How would you hold it at 60Hz? How would you hold the output voltage
steady with varying loads?
It is a VFD, so it at least holds the frequency steady at whatever you set it
to.
Hopefully there is some voltage regulation as well.
I'm mainly wondering if it requires the inductance of a motor on the output for
it to work.
I wouldn't chance it. Use a proper device like a UPS. I use a 3KW split
phase pure sine wave output UPS to run my whole house. It was made to
run on 12 12V batteries, I see a lot of them made for 16 12V batteries.
And what is the price of that unit?
