How come rooftop panels don’t need a battery? I’ve always wondered that. Does the grid truly act as a battery?

- mikestew 6y agoRooftop that does not have a battery and inverter will not power your house when the grid goes off. In order to power anything with Alternating Current, what would it sync to? By now I'm probably an expert on RV solar installation, but a dork at residential. That said, I believe residential solar pumps energy back into the grid, but does not power the house. The grid does the powering, then you get credit on your electric bill. In contrast to our RV, where solar charges the big battery, and the big battery runs the inverter for AC-related things (and DC stuff just runs direct off battery).
- mrfusion 6y agoThanks. I just feel like a small battery would need to come before the inverter on resodential but not sure why.
