Rechargeable solar battery for your home

Reliable energy when you need it most.

Power through outages with a home battery

Harness the power of the sun even when it sets

Our advanced solar batteries seamlessly integrate with your solar panels, capturing and storing excess energy during the day for use at night or during outages. With our reliable and efficient battery technology, you can enjoy round-the-clock clean energy and greater control over your electricity usage. Say goodbye to skyrocketing utility bills and hello to energy independence. Power your home sustainably with Sunrun's home solar battery and experience a brighter future, day and night.

Stay powered and protected

Take control of your energy

Build a cleaner future

Keep the lights on, protect your family, and secure your home during blackouts. Our 100-year-old utility grid is expensive, dirty, and susceptible to extreme weather. As blackouts become the new normal, a home battery backs you up with reliable, solar energy for your home and family.

A home battery can buffer you from increasing energy costs so that you have power when you need it most. While we can’t predict how much or how often utility electric rates will change or when the power will go out, you can always count on the sun rising each day. Take charge of your electric bill and get control of your energy needs now and in the future.

The benefits of solar-powered batteries go beyond your home. A home battery enables you to use more of the solar energy your panels produce, so you rely less on power from the grid. A cleaner and safer future starts today, and you can help create it by powering your home with the most abundant energy on earth.

Efficiency meets elegance with Tesla Powerwall

With 13.5 kWh of storage, Tesla Powerwall can back up even more of your home during outages and maximize your energy efficiency when utility rates are highest. And it seamlessly integrates into your home with a sleek and compact design.

Your home battery allows you to store the electricity your solar energy system produces during the day and use it when you need it most—such as in the evening during the time of use (TOU) peak pricing or when the electric grid fails due to an extreme weather event or physical damage to the equipment. (See below for more information on TOU peak pricing and whether it applies to your jurisdiction)

Home battery backup is a holistic solar battery storage solution that offers safe, reliable backup solar power for better control over your home energy use and cost.

Solar batteries can help you maximize the value of solar energy, protect your home from power outages, and reduce your carbon footprint by supporting the production of renewable energy. In California, local regulations allow you to do more with your battery. To optimize your system's overall value, we've programmed the battery to automatically help customers get the most out of their solar system by capturing their solar generated electricity and “shifting” it to when they need it most. This innovative solution optimizes potential savings by increasing self consumption during peak hours when rates are highest and reducing low-value exports back to the grid.

Many states and utility companies offer incentives, such as rebates or tax credits. 

One such incentive is net metering, which credits any excess power your solar system generates back to your electric bill. However, several states have chosen to adopt Time-of-Use (TOU) rates, which complicate how your net metering credits are calculated. Sunrun Shift can buffer you from peak TOU rates so that you may save even more on your electric bill.

Our rechargeable solar battery systems are designed to keep you on the grid during normal service times while providing reliable backup when the sun isn’t shining or during an outage. This is the most reliable and economical way to use your home battery system.
