Damn, those li-ion sure seem like a bad long-term solution. Very convenient that you use lifepo4 for at-home battery storage, and either lifepo4 or possibly sodium for grid scale.

Inverters aren’t a problem. China produces roughly half of them worldwide iirc. They’re dominant but you can source from elsewhere without an issue.

LiFePO4 is almost purely China, but those will last you 20 years, which is roughly 365 times as long as if you’re cut off from oil.
