At a previous house, I had sola installed (Back when the feed in tariff
was a nice $0.32 per KW.), but can confirm that when there was no mains
the inverter on our sola system did jack all... It would cycle around and
around looking for the mains so it could feed in any exces power.

I don't think anything in the house would work though, as we didn't have
batterys.... #-*(
