Ultimatley you still need battery or you will be wasting potential energy collection or it won't use solar when production isin't high enough to compeltely run the device off of. But yea this is a more practical idea as long as it's still coupled with a battery

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

Rooftop 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).

Thanks. I just feel like a small battery would need to come before the inverter on resodential but not sure why.
