Re battery banks:
My original version had a solar charge controller managing a lithium polymer battery bank, feeding an inverter.
The low voltage cutoff function... didn't. Dead lithium cells in the morning.
Version #2 had a better solar charge controller with lead-acid cells and the inverter. Worked okay for months until the solar charge controller developed a short.
(But before that the 2000W inverter blew up the first time I tried to use a small AC power drill. It was 5x overrated for the drill. Some people say 7x overrated is enough, others say 12x. I gave up and went all-DC for tools.)
Unlike The_Beav, my plans haven't been surviving first contact! :-p
I've charged a number of battery packs since then with my system, but haven't wired any in as online backups.
I'll try to keep everyone posted on how my Mk III battery pack goes!
