Unlike noisy motors that need fuel and care, the Powerwall is silent and takes care of things like turning on lights, charging the devices, and so on automatically.

Its main task is to store power, detect outrages, and automatically charge devices as a home’s energy source when the grid goes down.

Plus, if you have solar panels, you can use them to recharge the Powerwall, which means your home can run on its own electricity for several days.

Frequently Asked Questions

Nope! You must get a professional electrician to add the Powerwall at home. Or else, it could end up really bad!
