Tesla Powerwall 3

Powerwall 3 is a home battery designed to store energy for backup power, improved self consumption with solar, and stronger energy independence. With a built in solar inverter and app based monitoring, it is a streamlined option for solar plus storage.

Overview

Tesla Powerwall 3 stores energy from solar or the grid so you can use it when you need it most. During an outage, it can help keep your home powered based on your backup design and selected loads. We design systems to match your goals, whether that is essential backup, whole home backup, or maximizing self consumption.

Can Powerwall 3 provide whole home backup?

Often yes, but it depends on your main panel configuration, large loads, and the backup design. We confirm this during the site review and design process so expectations are clear.

Can I add more capacity later?

Yes. Powerwall 3 systems can be expanded to increase backup duration and energy storage as your needs grow.

Does it work with solar?

Yes. Powerwall 3 is designed for solar plus storage, helping you store excess solar production and use it later when the sun is down or during an outage.

Do I qualify for a tax credit?

Tax credit eligibility depends on project type and taxpayer situation. We can walk through common scenarios during consultation and confirm what applies to your project.
