Energy Storage for a Sustainable Home

Powerwall is a home battery that charges using electricity generated from solar panels, or when utility rates are low, and powers your home in the evening. Automated, compact and simple to install, Powerwall enables you to maximise self-consumption of solar power generation.


Powerwall comes in 10 kWh weekly cycle and 7 kWh daily cycle models. Both are guaranteed for ten years and are sufficient to power most homes during peak evening hours. Multiple batteries may be installed together for homes with greater energy need, up to 90 kWh total for the 10 kWh battery and 63 kWh total for the 7 kWh battery.


How it Works


Home solar installations consist of a solar panel, an electrical inverter, and now a home battery to store surplus solar energy for later use.

  • Solar panel Installed in an array on your roof, solar panels convert sunlight into electricity.
  • Home battery Powerwall stores surplus electricity generated from solar panels during the day or from the utility grid when rates are low.
  • Inverter Converts direct current electricity from solar panels or a home battery into the alternating current used by your home's lights, appliances and devices.

Contained within Powerwall's outdoor-rated enclosure is a rechargeable lithium-ion battery, a liquid thermal management system, a battery management system and a smart DC-DC converter for controlling power flow.
