A glowing white Powerwall at the center of a globe of solar panels

TeslaX Energy · Powerwall

Store the
sun.

A rechargeable home battery that powers your house day and night, backs you up through outages, and links with thousands of others to steady the grid.

How it works

Charged · backup ready

Always ready

Each Powerwall holds 13.5 kWh.

Charge from solar by day, run your home by night. Stack up to ten units to power everything — and the battery keeps a reserve charged for the moment the grid fails.

Time-based control

Buy low. Sell high. Automatically.

Powerwall stores energy when rates are cheap and discharges when they peak — and can export surplus back to the grid for credit. Your battery works the market while you sleep.

Virtual Power Plant

A power plant made of homes.

Over a million Powerwalls act as one. During peak demand they share stored energy back to the grid — preventing blackouts and earning owners credits.

Megapack

Grid-scale storage, by the acre.

The same battery technology, scaled for utilities. Each Megapack stores over 3.9 MWh — enough to power thousands of homes and replace peaker plants entirely.
