Solar + Brightbox™

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

Power outages impacted more than 2.4 million South Carolina residents from 2008 to 2017.1

A blackout can happen at any moment. 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 Charleston battery 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.9

You can monitor your Charleston solar energy production and storage with the online dashboard and mobile app.

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