What Sunrun home solar with Brightbox Is and How It Works

Sunrun home solar with Brightbox combines rooftop solar panels, an inverter, and a home battery to generate and store electricity at the customer site. The company describes it as a solar plus storage service that can power parts of a home during grid outagesSunrun, 02/20/2024Sunrun, 01/18/2024.

In a typical installation, Sunrun designs a rooftop solar array based on the homes historical electricity use and local roof conditions. Panels feed direct current into an inverter, which converts it to alternating current for home circuits while also coordinating charging of the Brightbox batterySunrun, 11/09/2023Sunrun, 09/21/2023.

During the day, solar generation first serves household loads, with any excess either charging the battery or feeding the grid where net metering programs exist. At night or during outages, the Brightbox battery can discharge to selected circuits, such as refrigeration, lighting, and basic electronicsSunrun, 12/14/2023Sunrun, 08/30/2023.
