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.

HOW IT WORKS

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 consumption.

Powerwall

The home battery is charged with electricity generated by solar panels or from the utility grid.

Inverter

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.
