Tesla Powerwall

Tesla’s home battery storage

Tesla Energy’s Powerwall is a home battery system that turns your home’s solar panels into an all-day resource – increasing self-consumption of solar – while also offering backup in the event of a power cut. The Powerwall enables more of your home’s electricity use to come from solar, which enhances solar functionality, and reduces energy costs.

Solar electricity at night

When solar panels produce more power than a home needs, the excess solar is sent back to the grid. 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. The result is greater self-consumption of your solar generation and reduced energy costs.

Emergency backup

In the event of a power cut, 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 power cut.

Powerwall features

01 Powers your home safely and economically

02 Wall mounted

03 Beautifully designed for your home

04 Indoor and outdoor rated

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.

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.


Each Powerwall has a 6.4 kWh energy storage capacity, sufficient to power most homes during the evening using electricity generated by solar panels during the day. Multiple batteries may be installed together for homes with greater energy needs.
