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Over the last 15 years, power outages across the U.S. have been getting worse.1 An out-of-date grid infrastructure can’t keep up with our increasingly plugged-in society.2 While generators offer a temporary solution in the face of a blackout, they’re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.
