Seamless backup power. With or without solar.
Powerwall detects grid outages and automatically becomes your home's main energy source. Protect your home from the next power outage and keep your lights on, phones charged, and no puddles under the fridge.
Self-Powered home. Just add Powerwall.
Powerwall integrates with solar to store excess energy generated during the day and makes it available when you need it, minimizing reliance on your energy retailer.
Time-Based Control. A Smart Way to Use Energy.
If your utility prices vary throughout the day, set Powerwall in Time-Based Control to maximise savings. Powerwall learns patterns in your energy usage and solar generation-- using stored energy to avoid purchasing high-cost electricity.
Compact and Simple
Powerwall is a completely automated system that installs easily and requires no maintenance.
Control Your Energy from Anywhere
Seamlessly monitor and automatically manage your Powerwall, solar, Model S, X, or 3 anytime, anywhere with the Tesla App
