This thread is great! We live in an area with somewhat frequent grid outages and rather than buy a generator, I'd love to have a bank of batteries in the house that would be able to power things for a day until the power comes back on. Other than a powerwall (which can do this, but doesn't seem like it's the main point of it) I can't see off the shelf options for what amounts to "a generator, but batteries instead".

Generally, your main power source (Grid, Solar, or Wind) is just too reliable. Also, small generators and the fuel to run them is just too cheap. I mean, it's not like I drive my house, couldn't I get (realatively) cheap sealed deep cycle lead acid batteries and use those? I guess the question is are lead acids actually any cheaper.

Orvin posted:I know it’s possible to use deep cycle lead acid batteries to create a power bank. It’s what phone companies use for their 50V phone system, and what electric utilities use for emergency DC power at substations. I just don’t think there is much of an off the shelf setup. It would totally be a DIY thing. Yeah, looks like if I want to do this, I'll have to go DIY.

Oh, for the thread: https://bigbattery.com/ It was started by the guy who went to jail for reselling Windows recovery CDs. Looks like they take "bad" batteries, break them down, test and condition the cells and build "good" batteries from them. Might be worth looking into for projects.
