In the meantime, I was wondering if anyone on this list has
experience with batteries and power inverters to use with my EVSE.
No experience, but I've thought quite a bit about it. I assume you're
talking about using your supplied Panasonic EVSE? I suppose your
charger wants about 1.6 kw at 120vac and 3.3kw at 240vac?
Lead batteries might work ok at with a 12v inverter at 1.6kw. It would
be more attractive to use 48v of lithium and 240vac. A little diddling
with your car might allow you to charge while driving.
Without talking about inverters, something from here should work:

You would need something over 30 amps for ~1.5kw and over 60 amps for
~3kw. Multiple batteries can be paralleled for the needed current. I
imagine you would want at least 2kwh? That would be about 40 ah @ 48v.
Two of these:

should give you 100ah (4.8kwh), up to 70 amps (~5kw) at a delivered cost
of just over $2k.
The advantages of these ebike packages is that:
1) chargers included
2) cells are supposed to be protected from:
a) over discharging
b) over charging
c) over discharge rate
