Powerwall 2

Proven home battery

The most widely installed home battery in the world, with an integrated inverter and a compact wall- or floor-mounted design.

Store your own energy

Bank solar energy during the day and use it at night, or charge from the grid when rates are low to spend less at peak.

Automatic backup

When the grid goes down, Powerwall 2 detects the outage and restores power to your home in a fraction of a second.

Why add Powerwall

Backup. Keep your home running through outages, automatically.
Savings. Use stored energy at peak rates instead of buying from the grid.
Independence. Rely less on the grid and more on the energy you make.
