Enphase SC200D111C240US01 IQ System Controller 3 Microgrid Interconnect Device

Enphase SC200D111C240US01 IQ System Controller 3 Microgrid Interconnect Device

The Enphase IQ System Controller 3 microgrid interconnect device connects the home to grid power, IQ Batteries, and solar PV with Microinverters.

The Enphase IQ System Controller 3 (SC200D111C240US01) is the definitive hub for modern residential energy management. Serving as a high-performance Microgrid Interconnect Device (MID), it seamlessly integrates grid power, IQ8 Series Microinverters, and IQ Battery 5P storage. By consolidating interconnection equipment into a single, pre-wired NEMA 3R enclosure, it streamlines the transition to grid-independent operation, ensuring your home remains powered even during total utility failure.

DOES NOT support Generator Integration

Product Hightlights:

• Advanced Microgrid Interconnect (MID) Logic: Unlike basic transfer switches, the MID functionality uses high-speed digital logic to detect grid outages instantly. It safely isolates your home from the utility in milliseconds, allowing IQ8 Microinverters to maintain a stable, localized microgrid without requiring large, expensive battery banks.
• Integrated Neutral-Forming Transformer (NFT): Designed for seamless split-phase 120/240V backup, the integrated NFT provides the necessary neutral reference for residential loads. This eliminates voltage instability and ensures your common 120V appliances, like refrigerators and electronics, run reliably during off-grid operation.
• NEC 2023 & PCS Compliance: The Controller 3 is built for modern electrical codes. Its integrated Power Control System (PCS) dynamically limits current backfeed to the main panel. This enables installers to avoid costly Main Panel Upgrades (MPU) by strictly adhering to the NEC 705.12 (120% rule) through software-defined current management.
• Safe Shutdown & NEMA 3R Durability: Safety is verified by an included System Shutdown Switch that acts as a rapid shutdown initiator for all grid-forming IQ8 units. Backed by a 10-year limited warranty, the NEMA 3R polycarbonate enclosure is engineered to thrive in extreme outdoor environments from -40°C to +50°C.
