7+ days of continuous power during an outage
When the grid goes down, solar energy will continue to power your home and charge your Powerwall.
On a typical day, Powerwall and solar will meet all of your home's energy needs.
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.
Time-based control — a smart way to use energy
If your utility prices vary throughout the day, set Powerwall in Time-Based Control to maximize savings. Powerwall learns patterns in your energy usage and solar generation-- using stored energy to avoid purchasing high-cost electricity.
