Our top solar pick
Backup power that skips the concrete pad
Not every home needs a unit bolted to the yard and plumbed for gas. The Anker SOLIX F3800 Plus arrives in a box, plugs into the wall, and puts out 120V/240V split-phase power, so it runs the fridge, the well pump, and the furnace with no electrician, no permit, and no fuel to store. Recharge it from panels and it keeps going after the tank would have run dry.
