Tesla Powerwall 3
More power. More control. More backup when you actually need it.
The Powerwall 3 Difference
All-In-One Simplicity
Powerwall 3 has a built‑in solar inverter, so there’s less hardware on the wall and less clutter on your switchboard.
That means a cleaner install, fewer boxes for you to worry about, and a system that fits neatly into everyday life.
Smarter Energy Savings
You can store power when it’s cheap or coming off your roof, then use it when prices spike.
Over time that shift adds up, cutting your power bills and reducing how much you rely on the grid.
Stay Powered Through Outages
When the lights go out on your street, your home doesn’t have to follow.
Powerwall 3 can keep your home or key circuits running through outages, and features like Storm Watch and adjustable backup reserve help you be ready before bad weather hits.
