Tesla Residential Battery
Tesla Commercial Battery

Tesla Powerwall 2 is designed to store any excess solar energy your PV system produces. This allows owners to power their home or business with free solar energy during the day or night and provide seamless and reliable power in the event of a blackout.  

Tesla Powerwall 2 also requires no maintenance and comes with a 10-year warranty. The Tesla Powerwall 2 will also be able to be used for:

  • Energy arbitrage
  • Peak shaving
  • Backup power
How is the Tesla Powerwall 2 different?

Powerwall 2 offers 13.5kWh of usable capacity and comes with an in-built inverter. This allows Powerwall 2 to convert DC power to AC power internally, eliminating the need for an extra hybrid inverter. This will result in lower installation costs and a much easier installation process.   

Safety and battery life is maximised thanks to the liquid thermal controls and touch safety technology.  

Users can seamlessly monitor and automatically manage your Powerwall, solar panels, Model S or X with the Tesla App. 

 With over-the-air software updates, Powerwall 2 will continue to improve and adapt to your lifestyle.
