I have a goal of setting up solar on my property in the woods that goes directly to a wall of batteries, maybe Tesla, maybe something else. But definitely not going back into the grid. Does anybody have suggestions or advice on how to do this? Who are the best companies doing this right now in New England? What products are folks using to store electricity? Are there any good resources for this kind of thing?
I like the MidNite solar controllers.
LiFePO4 batteries are great, with a few caveats:
- you must use batteries from the same batch, ie you can't upgrade capacity piecemeal, to avoid degrading the new ones
- cable lengths are important because even small differences in resistive losses between batteries can mean that one battery is doing more charging / discharging
- you can't charge below 0\*C, which I'm assuming could be a problem in New England
