Washington, D.C. – October 19, 2026 -- ConnectDER's full line of meter socket adapters is now approved for installation across Pepco's service territory in Washington, D.C., a market where 100-amp panels can force main service upgrades costing $1,800 to $5,800 before solar, storage or EV charging equipment can be connected. D.C. becomes the 54th utility in ConnectDER's network, which reaches nearly 40 million households.
The approval covers three products: the Solar MSA, the EV MSA and the IslandDER MSA. Each adapter plugs into the existing meter socket on the outside of the home. According to the company, this avoids main panel upgrades, service upsizing, circuit relocations, backup load panels and system controllers.
