  This might be a nice way to go off grid. I have 2 HDT Balance of System (BOS)

for my cost. Got at gov auction. No batteries.

Thoughts that come to mind:

Outback products are top drawer

This seems to be a 24 Volt battetry system, my cheapish solar charger has set battery parameters: flooded LA, Gel LA, but also a user selection that can be set for whatever such as LiFePO4 or any other chemistry if the user knows what they want. I would assume the Outback has a similar feature but I haven't found it yet. I am collecting LiFePO4 Headway 38120 cells when good deals come along. AlarmHookUp seems to be a good source of batteries, but not totally risk free.

Shipping would be a very significant cost. What general origin location would these BOSes ship from? I'm in Kalifornia, Usa.
