ConnectDER provides Meter Socket Adapters (MSAs) that attach directly behind the utility meter to create a plug‑and‑play interface for residential solar panels, battery storage, and EV chargers. The adapters integrate microgrid interconnect devices, current transformers, and voltage sensors, eliminating interior panel work and enabling code‑compliant installations in 15‑30 minutes while reducing labor and material costs.

Problem
Residential solar, battery backup, and EV charging installations often require extensive electrical work, including panel upgrades, circuit relocations, and the addition of separate system controllers, which increases labor costs, project timelines, and safety risks.
Solution
ConnectDER offers Meter Socket Adapters (MSAs) that install directly behind the utility meter, providing a plug‑and‑play interface for solar PV, battery storage, and EV chargers. The adapters incorporate built‑in microgrid interconnect devices (MIDs), current transformers, voltage sensing, and communication links, eliminating the need for interior panel work, drywall repairs, or additional service equipment. Installation is completed in 15‑30 minutes using a three‑step process—remove the meter, mount the MSA, reattach the meter—without special tools. The devices are compatible with multiple leading battery and EV charger brands and meet UL 414 standards, allowing installers to deliver safe, code‑compliant interconnections across a wide range of meter socket types. By simplifying the interconnection method, ConnectDER reduces labor hours, material costs, and project complexity while enabling faster deployment of residential distributed energy resources.
Target Audience
Primary customers are residential solar, battery, and EV charging installers and electricians who need a fast, code‑compliant interconnection solution, as well as utilities and DER manufacturers seeking approved behind‑meter devices.
