The Enphase IQ System Controller 3M
The Enphase IQ System Controller 3M is the core gateway to enabling reliable whole-home or partial-home backup in Enphase Energy Systems. Designed with built-in Microgrid Interconnect Device (MID) functionality, it simplifies system architecture by handling grid isolation during outages without external switching hardware. The 3M Controller integrates with the IQ Battery 5P and IQ8 Microinverters to deliver stable backup and solar operation.
Built for flexible configurations and ease of installation, the IQ System Controller 3M supports IQ Meter Collar integration for whole-home backup on homes with combo meter-main panels—without requiring load relocation or service rewiring. With a NEMA 3R outdoor-rated enclosure, it offers durable performance in any environment while streamlining install time with features like color-coded wiring, neutral-forming transformer, and multi-directional conduit entry.
Enphase IQ System Controller 3M Features
- Installer-Friendly Design: Mounts on a single stud with integrated brackets and includes color-coded wiring, a neutral-forming transformer, and conduit entry from three directions.
- Built-In Microgrid Interconnect Device: Safely isolates the home during outages and enables whole-home or partial backup with IQ Batteries and Microinverters.
- Flexible Energy Capacity: Supports up to 15.4 kVA of PV with 80 kWh of battery storage or 30.7 kVA of PV with 40 kWh of storage.
- Supports IQ Meter Collar Integration: Simplifies whole-home backup in meter-main panel homes without the need for load relocation or special breakers.
- Enhanced Safety Controls: Includes a System Shutdown Switch that disconnects PV and battery power and acts as a rapid shutdown trigger for grid-forming IQ8 inverters.
Scalability – Enphase IQ System Controller 3M
The IQ System Controller 3M is ideal for homeowners seeking a highly flexible and scalable energy solution. It integrates natively with Enphase IQ Batteries, IQ8 Microinverters, IQ Gateways, and the IQ Meter Collar. This allows for simplified whole-home or partial backup configurations—whether it’s a new installation or an expansion of an existing Enphase system.
Enphase IQ System Controller 3M Review
The IQ System Controller 3M is a comprehensive solution for enabling backup functionality and energy independence within the Enphase ecosystem. It offers integrated MID functionality, streamlined installation, and compatibility with a wide range of Enphase components including the IQ Meter Collar and IQ Batteries.
Installers benefit from reduced complexity with pre-integrated features like a neutral-forming transformer, hold-down bracket integration, and flexible conduit routing. The 3M controller supports up to 30.7 kVA of solar PV and 40–80 kWh of battery capacity, enabling a broad range of system designs. With IQ Meter Collar compatibility, it unlocks whole-home backup for meter-main combo panels without service rewiring or load relocation—streamlining upgrades under utility constraints and NEM 3.0 environments.
