Reliable Home Battery Storage + Solar Backup Power
We’ve partnered with Tesla to bring you the safest, most efficient battery backup system on the market. Designed to work with your solar system, the Tesla Powerwall stores the electricity generated by your solar panel for the times you really need it, bringing you one step closer to energy independence.
What Is a Tesla Solar Battery?
Tesla solar batteries, commonly known as the Tesla Powerwall, are rechargeable lithium-ion batteries designed for small-scale home energy usage. As a lithium-ion battery, the Powerwall has a significantly higher energy density than lead batteries, meaning it can store and discharge more energy to power more appliances for longer. The Powerwall also has a superior depth of discharge to lead batteries and are more efficient, meaning more of the energy stored can actually be used.
How Do Tesla Batteries Pair with Your Home Solar System?
When the sun is out, your home’s solar system collects that solar energy, which it then uses to directly power your home. If you don’t have immediate energy needs matching the amount of energy stored, that excess energy can be saved in your Tesla home battery for later use instead of sending it back to the power grid.
In the event of a power outage, your Powerwall will automatically detect the outage, disconnect from the grid, and restore power to your home, ensuring complete emergency preparedness and reliability during blackout restoration efforts. Your connected loads continue to run without interruption, and your system will continue its normal generation to replenish energy storage during daylight hours.
One Powerwall can provide 13.5 kWh per charge and can power large appliances for a short period of time or small appliances for a long period of time. With active monitoring and sunshine after a blackout event, a Powerwall can keep your essential loads powered for a week or more. Energy storage levels can be monitored from the Tesla app in real-time so you can shed and adjust loads depending on energy available.

What Happens During an Outage if I Don’t Have a Tesla Backup Battery Paired with my Solar System?
When the power goes out in your home, the solar panels will stop working and automatically disconnect from the grid to maintain the safety of the utility workers attempting to restore power. Once the power is restored, your system will continue production after a few minutes.
If it is important for you to maintain power during a blackout, we recommend adding one or more Tesla Powerwall home batteries to your system.
How Many Tesla Solar Batteries Do I Need?
Like solar panels, the number of Tesla Powerwall home batteries that you will need will depend on your home’s needs and usage. While one Tesla battery is sufficient to cover your basic energy needs, we generally recommend two or three battery back up systems to provide the best comfort and value.
Where Will a Tesla Backup Battery Be Placed?
A certified installer from Tesla can mount a Tesla Powerwall on any wall, usually outside of your house or inside of your garage.
