If you have an existing solar panel system and you don’t currently have a battery, one of the great things you can do with the Tesla Powerwall is you can install two or more power walls and do what’s called whole-home backup.
When you do a whole-home back up what we do is we take all the circuits in your existing main service panel, and we move it to a dedicated sub-panel. We then install your gateway, and if the power goes out, all the circuits in your home will be backed up, which means that you can run anything in your home off the powerwalls for as long as the powerwalls have power.
If you only have one Tesla Powerwall, we can do what’s called a partial-home backup. We would take certain circuits out of your main service panel and put it into a dedicated load center. Whenever the power would go out, that power wall would then power those dedicated circuits.
Typical circuits that people backup would be refrigerators, deep freezes, maybe basic lights in the bathroom or the kitchen, alarm systems, internet, computer or entertainment systems.
