Where did you get 1,000$/KWH of storage? Even at small scales (household-sized batteries, ~10~15KWH) prices are currently around 300$/KWH for lithium batteries including shipping in a 3rd world country (I know, because I live in a country where there's no 24/7 grid power and I moved my house to solar+batteries 2 years ago).

I'm pretty sure at the kinds of scale you'd need for a country price per KWH would be significantly less.

I just googled solar battery cost and took the cheapest in the result that came up: https://www.solarchoice.net.au/blog/battery-storage-price/ It is possible that the numbers that come up there are too high.
