Clean Backup for the Next Blackout

Over the last 15 years, power outages across the U.S. have been getting worse.1 An out-of-date grid infrastructure can’t keep up with our increasingly plugged-in society.2 While generators offer a temporary solution in the face of a blackout, they’re dirty, noisy, and at worst dangerous.3 The good news? We’re here to make energy independence safe, simple and hassle-free.

Power through blackouts with a clean, reliable solar battery that puts you in control. You can choose what and how much you want to backup in case of an outage.

Maximize Your Solar Savings

With electricity rates increasing over the last 10 years,4 going solar just makes financial sense. So if you’re thinking about joining the bright side, why not set yourself up for success? With Brightbox, Sunrun also intelligently and remotely optimizes your battery to maximize savings.

Depending on your neighborhood’s electricity rate structure, Brightbox can offset energy costs when electricity rates are at their peak. And in a blackout, your Brightbox offers a sustainable source of energy so you don’t have to spend on unruly and expensive generators. Maximum savings? We’ll take that any day.

Frequently Asked Questions

Brightbox is a holistic battery storage service that offers you clean, safe, reliable backup power to have better control over your home energy use and the cost you pay for it.

Brightbox Solar Battery Storage System saves you money on utility bills, protects your home from power outages, and also reduces your carbon footprint by supporting the production of clean, renewable energy.

Brightbox allows you to store the electricity your solar system produces during the day and use it when you need it most. Like in the evening, at night, or when the electric grid fails due to an extreme weather event or physical damage to the equipment.

While some battery units allow you to store electricity directly from the grid; with Brightbox Solar Battery Storage Service, the energy is harnessed entirely from the sun. Meaning it’s 100% clean, renewable and free of charge, so you don’t have to pay your utility for the extra power to charge your battery.

The installation of Brightbox is a relatively simple process. It’s about the size of a water heater, and the system is mounted on a wall, usually inside your garage or outside of your home.

Brightbox stores energy to provide reliable backup when the sun isn’t shining or in the event of an outage. However, one Brightbox battery can’t store enough power to supply your home’s entire electricity consumption for more than 10+ hours, which is why you have to stay connected to the electric grid.

Just like solar panels, the size of your Brightbox Solar Battery Storage Service is determined by your unique energy needs and habits. Factors such as the amount of electricity you use at home and the devices and appliances you want to back up will play a key role when selecting the right battery option for you.

While Brightbox requires an Internet or cellular connection to monitor your energy storage and usage efficiently, it can still operate without it. If for some reason Brightbox happens to go offline, you can resume your usage tracking when your internet connection is back to normal.

Most residential batteries are installed and configured with baseline settings by your solar provider. Batteries last anywhere between 10 and 15 years, and manufacturers typically offer a 10-year warranty. Still, Brightbox is more than battery storage; it’s a holistic service that includes professional maintenance and monitoring for 20 years: two actions which may prolong your battery unit’s life.
