After a basement flood years ago, I installed a solar-battery-inverter system that could power my sump pumps for many hours.
You will never guess what happened.. It never flooded again, and the grid has never failed while it was raining, since then.

The 48v battery pack (car batteries) are getting very old. I'm thinking of replacing them, or just scraping the whole thing.
I can use a gas generator to power those pumps, if it ever becomes necessary.

All the extra CO2 is over-greening my backyard. I have to remove vegetation from the panels once a week now..
