Introducing Powerwall 2
The AC coupled Tesla Powerwall 2 home battery
The Powerwall 2 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, load shifting and backup power.
Powerwall’s electrical interface provides a simple connection to any home or building. Its revolutionary compact design achieves market-leading energy density and is easy to install, enabling owners to quickly realise the benefits of reliable, clean power.
Powerwall 2, AC coupled home battery is more suited for homes with solar already installed, due to the lack of battery inverter and for homes that need standalone batteries for either backup or utility grid services. Tesla Powerwall 2, AC version, can also be used for new solar installations, although the DC Powerwall 2 is more suited for installation as part of a new solar and home energy storage solution.
