Won't work for an inverter off my truck pack, as it's only 320v.
Won't work with the 'battery' connection, but you could hook you truck battery
to the PV input.
In order to get the battery connection to work you'd have to hack the
communications protocol between the inverter and the battery controller. What
others have done is just hook their EV pack to the PV panel input, supposedly
any DC input between about 120V and 550V should work.
Any well documented cases of hooking a battery pack to the PV input?
I've heard too many stories about frying inverters that way in the past, as the
MPP circuit really doesn't like a low-impedance input like you get from a
battery pack.
If 36vdc batteries feeding grid tie micro inverters fits your
description, I've written about what I do as a PowerWall supplement.
