Just make one large enough to power my house for 2 weeks and let me use solar completely detached from the grid. I'll put it on the side of my house.
maybe in a shed off the side of your house? i would not want that fire attached to my structure in a failure.
It's not lithium. This battery wouldn't be a fire hazard.
if it's charged it's a fire hazard. i've seen nickel cadmiums go up in weird ways. we're talking about your largest investment, prudence is warranted.
My house is charged. It's a fire hazard.
It is waaaaaaay more likely that they'll be an issue with an EV or ice car in your garage to catch fire than a storage battery like this. This or sodium batteries can't have a runaway thermal "event". The chemical reactions aren't there for it.
That's doable right now pretty much, in that the cost of existing batteries is in proportion to the other stuff you'll need.
The sodium batteries rolling out to market right now should be good for it. Just waiting for them to get out and into use for a few years to make sure their isn't any immediate unforseen bugs. I just want a 30 year battery and not a 10 year, and time itself degrades lithium based batteries quite a lot. They can make one that will last over 500,000 ev miles, but don't count on it doing it and lasting 20+ years.
