Known as Off-the-Grid houses, this is how Enertia got its start (About Enertia
) back in the 1970’s. Our early customers had to go off grid - they did not have access to utility power. They had to make sacrifices back then, but the the technology is tremendously better now, and PV-to-battery-to-inverter electricity is cleaner and more stable than the utility. Soon Tesla is about to offer battery packs for Off Grid houses, by recycling their used car power packs which still have life as fixed, not mobile, sources of energy.
“Off Grid” means completely independent of, and not connected to, the utility grid.
