Powerwall is a home battery that charges using electricity generated from solar panels, or when utility rates are low, and powers your home in the evening. It also fortifies your home against power outages by providing a backup electricity supply. Automated, compact and simple to install, Powerwall offers independence from the utility grid and the security of an emergency backup.
Tesla home batteries maximize the usefulness of your solar panels and offer a variety of backup electricity supply solutions. You can even go off the grid.
Solar electricity at night
Powerwall stores electricity generated by solar panels during the day and makes it available to your home in the evening. This bridges the gap between peak solar and peak demand, allowing you to use your photons when you need them.
Go net zero
Combine solar panels and one or more Powerwall home batteries to power your home independently from the utility grid. A net zero energy rating means that your home produces as much energy as it consumes, but is still connected to the utility grid for periods of high demand.
In the event of a utility outage, Powerwall can power your entire home or select appliances with an uninterrupted supply of electricity. When installed along with solar panels, Powerwall will allow your home to use solar generated electricity during a utility outage.
