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.
Keep your lights on
All Tesla solar systems integrate with Powerwall, a compact home battery that reduces your reliance on the grid by storing your solar energy for use when the sun isn’t shining.
Get more energy independence
Electricity costs are rising across the country. And utilities charge more when they know you need it most. Instead, make your own clean energy, store the excess for peak times and power outages and break free from the power company grid games.
Control your own home
With the Tesla app, you can monitor your solar energy in real time. Set your preferences to optimize for energy independence, outage protection or savings. Control your system from anywhere with remote access and instant alerts.
Powerwall+ vs. Powerwall
The Tesla Powerwall+ is an integrated solar battery system that stores energy from solar production. Powerwall+ has two separate inverters, one for battery and one for solar, that are optimized to work together.
The Tesla Powerwall is a fully-integrated AC battery system for residential or light commercial use. Its rechargeable lithium-ion battery pack provides energy storage for solar self-consumption, time-based control, and backup.
How solar + batteries work with your home:
Use your stored solar energy during the day or night to power household loads (great for avoiding expensive Time of Use rates)
Or when the power is out during an outage
Recharge from the sun and repeat!
