Its a lithium-ion battery. The price is quite good and lithium batteries have a long life span. Plus, it will both store solar energy and serve as a backup power generator.

The batteries are the key -

you wouldn’t have to charge them from solar.

You could have your backup generator run when the batteries get low and charge them back up, and the generator could shut off.

Also, to keep them topped off, charge them from utility power for emergencies.

Tesla plans to start shipping the units to installers in the US by this summer.

I'm in with this one...
