IslandDER™ is a Meter Socket Adapter (MSA) that functions as a Microgrid Interconnect Device (MID). It safely disconnects a home from the grid during an outage, allowing residential energy systems like solar, batteries, and Vehicle-to-Home/Vehicle-to-Grid (V2H/V2G) to create a "microgrid" and provide backup power.
Key Features
Fast Installation & Isolation: 15-minute install with MID integration for home backup and isolation.
Fail-Safe Override: Manual MID override switch (under tool-access cover) to prevent extended outages if third-party equipment fails.
Integrated CTs: Built-in Current Transformers eliminate the need for separate CT installation.
Real-Time Data Access: Pluggable and reversible connection for real-time whole-house current and voltage data.
Broad Meter Compatibility: Works in virtually every residential U.S. meter — ideal for meter-main combo panels.
Reliable Cooling: 200A continuous current via passive cooling (no fans).
Safety & Compliance: NRTL listed to UL 414 for use with UL 1741/3141 systems.
Easy Inspection: Toolless removal for easy meter socket inspection.
