ConnectDER develops meter-socket hardware that accelerates interconnection of solar, battery storage, and EV charging by turning the meter socket into an all-in-one connection point. The company’s next-generation Meter Socket Adapter (MSA), the IslandDER™, enables seamless islanding of solar, batteries, EVs and other DERs to provide whole-home backup and resiliency. Its products install in minutes and are marketed as costing 10% or less than typical service-panel or utility interconnect upgrades, addressing an estimated U.S. market where 60 million homes lack capacity for solar or EV charging without costly upgrades. ConnectDER reports over 25,000 adapters in operation and approvals to sell in more than 20 states covering over 16 million households. The company has public endorsements from partners such as Blue Raven Solar and is positioning its offerings to simplify installations, reduce errors, and expand entry-level installer jobs. ConnectDER plans to use new capital to expand markets, scale manufacturing, and continue product innovation aimed at nationwide sales in the next few years. ConnectDER develops meter-collar technology that provides a low-cost, one-hour install in a single device to upgrade residential electric power systems for grid-ready solar photovoltaic integration regardless of a home’s age or amperage. The solution enables installations without complex and expensive upgrades to circuit-breaker panels or in-home wiring and without adding more amperage from the utility. ConnectDER’s product can be optimized to offer connections for electric vehicle chargers and backup power systems in the near future. Led by founder and CEO Whit Fulton and based in Philadelphia, the company is already operating in 17 states and has deployed over 15,000 units nationally to date. ConnectDER plans to use new funding to scale its existing solar adapter into new markets, launch a new EV product line, and develop a next-generation product suite for multi-asset electrification and integration. ConnectDER's flagship product, the Smart ConnectDER meter collar, turns the utility meter socket into a grid-ready, plug-and-play interface for residential solar, storage and EV charging. The meter collar enables rapid interconnection of grid-ready DERs, provides superior data to utilities, and offers a low-cost alternative to traditional wiring methods. The technology lowers installer costs while unlocking alternative tariff models and grid management capabilities for utilities. Utilities including Consolidated Edison, Arizona Public Service, Entergy, and Pennsylvania Power and Light deploy ConnectDER's solution. The company said it will use new capital to scale operations and supply chain and to enhance core solutions for energy storage and other fast-growing residential applications across North America. ConnectDER expects to launch several new products beginning with Smart ConnectDER Version 4 at DISTRIBUTECH. ConnectDER builds a meter collar hardware product that reduces upfront installation costs for rooftop solar and gives electric utilities real-time management over distributed energy assets. The device is designed to let residential solar connect to the grid cheaply, safely, and rapidly while avoiding home wall penetrations. The company says widespread deployment would cut greenhouse gas emissions, reduce environmental damage from fossil fuel extraction and combustion, and decrease reliance on government subsidies. ConnectDER’s solution also aims to enable highly managed distributed energy assets and boost grid resiliency. The company closed a $1.1M Series A, providing early-stage capital to advance commercialization and deployment. The funding was supported by a collaboration between PRIME Coalition and Investors' Circle and several philanthropic and impact-minded angel backers.
