Solar Battery Pack

It’s the holy grail for home owners who have invested in solar panels – a home battery storage
system that turns your home’s solar panels into an all day resource!

The Tesla Powerwall is a wall-mounted battery system for residential or light commercial use. Its rechargeable lithium-ion battery pack 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 achieves unprecedented levels of safety in home energy storage. It is a factory assembled, fully certified unit that contains no user-serviceable parts.

Why Powerwall?

Solar electricity at night

  • Powerwall stores electricity generated by solar panels during the day and makes it available to your home in the evening.
  • This bridges the gap between peak solar and peak demand, allowing you to use your photons when you need them.

Go net zero

  • Combine solar panels and one or more Powerwall home batteries to power your home independently from the utility grid.
  • A net zero energy rating means that your home produces as much energy as it consumes, but is still connected to the utility grid for periods of high demand.

Emergency backup

  • In the event of a utility outage, Powerwall can power your entire home or select appliances with an uninterrupted supply of electricity.
  • When installed along with solar panels, Powerwall will allow your home to use solar generated electricity during a utility outage.

Beautifully Functional

  • Current generation home batteries are bulky, expensive to install and expensive to maintain. In contrast, Powerwall’s lithium ion battery inherits Tesla’s proven automotive battery technology to power your home safely and economically. Completely automated, it installs easily and requires no maintenance.

How it Works

  • A typical Powerwall system includes solar panels, an inverter for converting electricity between direct current and alternating current, a meter for measuring battery charge, and in backup applications, a secondary circuit that powers key appliances. Which components are required depends on how you use your home battery.
