What is the Tesla Powerwall?

Tesla Powerwall is a fully integrated AC battery system for residential or light commercial use. It’s rechargeable lithium-ion battery pack provides energy storage for solar self-consumption, time-based control, and back up in the event of a power cut.

Powerwall’s electrical interface provides a simple connection to any home or building.

It’s revolutionary compact design achieves market leading energy density and is easy to install, enabling owners to quickly realise the benefits of reliable clean power.

What can I use Powerwall for?

Powerwall can be used for a variety of applications, including:

Self-Powering your Home
With Powerwall you can use more of your solar by storing the excess energy and using it at night, which roughly doubles the amount of solar energy that directly powers your home.

Home Energy Monitoring
You can monitor your solar, Powerwall and home energy use in real time with the Tesla mobile app.

Time-of-Use Load Shifting
If your utility offers a time-of-use rate plan, Powerwall can charge when rates are low and use that energy during expensive times to reduce your electricity bill. This feature will be available at a later date by an over-the-air update.
