Solar + Brightbox™

Add Brightbox, Sunrun’s battery storage service, to your solar installation in South Carolina. This can help you keep your devices and appliances running during outages, cloudy days, rainy afternoons, or at night.

Between 2008 and 2017, more than 2.4 million South Carolina residents were impacted by power outages.1

A blackout can happen at any time. Some are short, but others can go on for hours or days at a time.

Brightbox can help you back up your entire home with a Tesla Powerwall, or you can back up just the rooms you need with an LG Chem solar battery.**

When the sun is out, Brightbox can store clean and affordable back-up power for later use.

Brightbox is the South Carolina back-up storage solution that puts you in control. It can turn on during an outage and will work to recharge until the grid's restored.

Unlike generators, Brightbox doesn’t run on fossil fuels, which produce carbon monoxide (CO) that’s dangerous for your health.10

Brightbox is fueled by the sun, so you can forget about the hassle of buying expensive gas and diesel. You can also monitor your South Carolina solar power production and storage daily with the online dashboard and mobile app.

Our monthly lease and prepaid plans include 24/7 proactive monitoring and maintenance to ensure your system works smoothly. This perk sets Brightbox apart from the average solar battery in South Carolina.

**One Tesla Powerwall stores 13.5 kilowatt-hours (kWh) of usable electricity, which can be used to back up the home for a day. An LG Chem solar battery holds 9.8 kWh, which can be used to back up essential parts of the home from 8 to 12 hours. 

***Customer’s ability to monetize rebates, incentives, and tax credits depends on several factors, including, without limitation, continued state subsidization of these policies, the applicable Sunrun product type, and whether a customer purchases or leases a home solar system from Sunrun.
