Supply-Side Solar and EV Interconnection
in Minutes

Help your customers go solar and charge an EV without requiring an electrical panel upgrade.

Developed in partnership with utilities, ConnectDER’s products were created with installers and customers in mind. Click below to see if ConnectDER products are approved in your area.

How It Works

ConnectDER meter socket adapters are installed directly between the utility meter and the meter socket, creating a simple, accessible, outdoor interconnection point for DERs such as solar and EVs. Avoid old, difficult-to-access and non-code compliant main breaker panels and reduce the need for highly technical and dangerous site visits.

Simplify and standardize interconnection.

Our adapters work in virtually every residential meter socket in the U.S. and provide a quick, consistent, and easy-to-train process for tie-in.

Avoid costly and time-consuming main panel upgrades.

These upgrades typically cost thousands of dollars. ConnectDER saves homeowners $1000 on average.

Reduce time onsite, logistics challenges, and inspection issues.

Our technology provides a consistent, reliable method that does not alter existing service equipment, minimizes installer impact inside the home, and is easy for electrical inspectors to understand.

Don’t Just Take Our Word For It; Hear Why Installers Love Us

Meter socket adapters are paving the way for the future of Virtual Power Plants (VPP) and energy storage. By helping to reduce costs, we’re excited to see more of these innovative solutions like IslandDER™ becoming available in the market.

Jake Bastien, CEO | Icon Power - Arizona

Retrofits are usually slowed down by panel upgrade requirements, high labor costs, and long permitting timelines. With IslandDER™, we can bypass costly electrical work inside the home, cut install time dramatically, and reduce disruption for homeowners, making solar plus storage retrofits faster, cheaper, and far more scalable.

Catt Roose, VP of Operations | Haven Energy - California

By integrating IslandDER™ with the battery system, we’re able to deliver a comprehensive whole-home backup solution with 50% less installation time and over 50% cost savings. The need to install CTs in tight electrical panels has been eliminated, streamlining the installation process even further.
