I'm always curious why homes in the US need energy storage systems, basically UPS for the house? I live in China, and the only times my UPS for the home server tripped in the last 5 years were scheduled maintenance that lasted for no more than 30 minutes, and even that was rare...

Remote rural China or big city China on the same circuit as a major hospital / government department ?

We live in a big city now (though not exactly close to hospital or government), but my wife's hometown is a smallish rural town, and power outage is also extremely rare (less than once per year?) in the past decade or so. If you need e.g. oxygen ventilation at home, probably safer to have a backup generator or UPS, but I don't think anyone I know would need one at home.

I don't know about "remote rural". But in those places, I don't think anyone could afford an energy storage system even if needed......

Saving money. You install solar plus storage and don't need to pay for electricity.

Oh okay, that's fair. How long would you achieve breakeven, i.e. save enough money from electricity to cover the initial cost?
