My electric bill in CA was ~$300/month.

$3600+/year.

Great investment, and no more power failures. But also, OP said this technology doesn't exist. You're pivoting to it exists but you can't afford it. Different question.

Downvoted because daring to say consumer power storage technology already exists conflicts with some sort of comforting folksy narrative that it doesn't? How is that in any way "Hacker" like? I thought we were supposed to be the bleeding edge types rapidly adopting the new toys. My bad? Downvote this too because "this isn't reddit" amIRight?
