Sunrun Expands Brightbox Solar Battery Service To Massachusetts

Recently, about two million people on the East Coast were left without power by a ‘bomb cyclone’, including several hundred thousand in Massachusetts. As a response to the outages, Sunrun is expanding its home solar battery service to Massachusetts. Called Brightbox, Sunrun’s lithium-ion battery system is designed to work well with a home solar power system. The solar panels generate electricity during daylight hours when there is adequate sunlight to charge the battery, which can be used during a power outage. Sunrun says on its site, “Our lithium-ion battery is charged by your solar panels, and powers on during an outage for up to 10 hours. When the sun comes back out, your panels start recharging again.” The Brightbox system uses an LG Chem battery.
