Enphase IQ System Controller 3M 200A System Controller

About This Product

The Enphase IQ System Controller 3M 200A System Controller is a residential energy system controller designed to connect utility power, Enphase IQ Batteries, and solar PV within an Enphase backup system. Model SC200D111CMC1US01 includes an integrated neutral-forming transformer (NFT) and is specifically designed to operate with the Enphase IQ Meter Collar. Together, these components provide microgrid interconnection functionality and allow a properly configured Enphase system to transition between grid-connected and backup operation.

Who This Product Suits

The Enphase IQ System Controller 3M suits US residential Enphase installations requiring whole-home backup with an IQ Meter Collar. It is intended for systems combining compatible Enphase microinverters, IQ Battery 5P storage, and the required Enphase communications and metering equipment. The 3M configuration is particularly useful where the installer wants to integrate backup through the home’s existing main panel without relocating backed-up circuits to a separate backup load panel. System design, service equipment configuration, conductor sizing, overcurrent protection, and installation must comply with applicable NEC and local utility requirements.

Specifications Explained

• Model: SC200D111CMC1US01, Enphase IQ System Controller 3M.
• Electrical service: Designed for 120/240V, 60 Hz residential applications with up to 200A overcurrent protection and 160A maximum continuous input/output current through the back-fed breaker path.
• Microgrid interconnection: Provides the system control needed to isolate the home from the utility grid and support backup operation during an outage.
• Neutral-forming transformer: An NFT is integrated into the controller for supported Enphase backup configurations.
• IQ Meter Collar support: Designed to pair with the Enphase IQ Meter Collar for whole-home backup integration through the existing main electrical panel.
• Battery support: Supports IQ Battery 5P installations up to 40 kWh without an Enphase Power Control System and up to 80 kWh when used with the supported Power Control System configuration.
• PV integration: Supports compatible Enphase IQ Series microinverter-based solar systems and provides rapid-shutdown system control for supported configurations.
• Load management: Supports integration with the Enphase IQ Load Controller where managed loads are required.

Summary

The Enphase IQ System Controller 3M is the central grid and backup interface for compatible Enphase solar-plus-storage installations using the IQ Meter Collar. It combines microgrid interconnection functions, an integrated neutral-forming transformer, PV and battery connectivity, and system control in a purpose-built enclosure. For installers building an Enphase IQ Battery 5P whole-home backup system, the 3M provides a streamlined approach that can avoid relocating household circuits to a dedicated backup panel.
