ConnectDER

ConnectDER designs and manufactures meter socket adapters (MSAs) that serve as plug-and-play connection points for distributed energy resources — including residential solar, battery storage, EV chargers, and heat pumps — at the utility meter socket, eliminating the need for expensive panel upgrades. Founded in 2011 in Philadelphia, PA, the company works with utilities, solar installers, and electricians across North America to simplify and accelerate the deployment of clean energy technology. ConnectDER has shipped over 40,000 devices and holds utility approvals across more than 60% of the U.S. residential market, including California's three largest utilities. The company has raised over $70M in funding, including a $35M Series D led by Decarbonization Partners (a BlackRock and Temasek joint venture).
