Absolutely there is, a decent sized solar system with a battery bank can provide power regardless of the electrical grid being up or down that’s the whole point of disaster preparation
There is a way to do it. But these solar companies doing it now don’t set them up in that manner. No batteries, just a direct feed into the grid.
I know because a friend of mine sells them. The way they’re configured and installed you can’t use the electricity generated in your own home. That’s one of the reasons I passed on it.
That and the ROI didn’t work.
