Tesla Powerwall

Powerwall is an integrated battery system that stores your solar energy for backup protection when the grid goes down.

Backup Power During Outages

Protect your home from a power outage with seamless and reliable backup power. Powerwall is an integrated battery system that stores your solar energy for backup protection, so when the grid goes down your power stays on. Your system detects outages and automatically recharges with sunlight to keep your appliances running for days.

Self Power Your Home


Use solar and Powerwall to reduce reliance on the grid and run your home off solar day and night. The Powerwall is a compact home battery that reduces your reliance on the grid by storing your solar energy for use when the sun isn’t shining. You can add additional Powerwall units to further lower your carbon footprint and increase your solar self-reliance.

Time-Based Control

Reduce your electricity bill if your utility offers a time-of-use rate plan. In areas that offer time-of-use (TOU) rate programs, a solar system paired with a Tesla battery can store your solar production during the day and shift it to times when TOU rates are high. With the Tesla app, you can also monitor your solar energy in real time and set your preferences to optimize for energy independence, outage protection or savings. Control your system from anywhere with remote access and instant alerts.
