Tesla Powerwall is a home battery that maximize the usefulness of your solar panels.

Energy Storage for a Sustainable Home

Powerwall is a home battery that changes 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 maximize self-consumption of solar power generation.

Why Powerwall?

Tesla home batteries maximize the usefulness of your solar panels and offer a variety of backup electricity supply solutions. You can even go off the grid.

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.

Tesla Powerwall

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.

Solar panels

Panels convert sunlight into

electricity that charges Powerwall

and powers your home during the

day. Without solar, Powerwall can

reduce time of use power bills by

strategically shifting energy



The home battery is charged with

electricity generated by solar panels

or from the utility grid.






The inverter converts direct current

electricity from solar panels, the grid

and Powerwall into the alternating

current used by your home's lights,

appliances and devices.


All Powerwall installations require a

compatible inverter. To maximize

solar consumption, a meter is also

installed to measure solar production

and home energy use.

Electrical Panel

Electricity from the inverter is sent to your

home's electrical panel. For applications

without solar, and night time, electricity

generated by the power company is sent

from the electrical panel to the inverter

to charge the Powerwall.




Backup panel and switch

Some backup installations may require a

secondary electrical panel containing the

critical appliances and outlets you wish to

back up. An electrical switch automatically

activates the backup panel during a power

company outage.

When installed with solar, this switch can keep

your solar producing during an outage.

Backup is an optional feature when installing

to maximize solar or shift energy consumption.



Tesla Powerwall, twice power


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.
