Rooftop panel we used it where there was no electricity to charge our car battery. We hooked it up 18 V were showing on the panel hooked it to the battery in the car directly and 20 minutes later Car was running.
If I don’t know, I wouldn’t have bought one for the house that plugs in the wall, cause this one can work anywhere up in the mountains in the desert or in your backyard
