Product Overview
The Enphase IQ System Controller 3 (SC200D111C240US01) connects the home to grid power, IQ Battery 5P, and solar PV. It provides MID functionality with automatic grid-to-backup transition and does not support generator integration.
Storage OCPD is 2 × 80 A. Battery capacity on the Americas datasheet is up to 40 kWh without PCS and 80 kWh with PCS — higher than the 3G model.
Best For
- Enphase IQ Battery 5P backup without a generator on the Controller 3 platform.
- Larger IQ Battery 5P stacks that need the higher kWh limits shown for Controller 3 (with or without PCS).

What You May Also Need
Usually required
- Main/load and DER breakers sized to the job (order separately).
- CTRL-SC3-NA-01 for wired CTRL.
- IQ Gateway / Combiner path and consumption CTs as required.
May be required
- IQ Load Controller for essential-load control during outages.
- IQ System Controller 3G if the design needs generator support instead.
Optional upgrades
- Monitoring & Control: Related monitoring hardware.
Check current manufacturer documentation before combining components, especially batteries, inverters, communications equipment and system-control hardware.
Important Considerations
- Controller 3 does not support generator integration — use SC200G111C240US01 (3G) when a generator is required.
- Americas datasheet Compatibility lists IQ Battery 5P, IQ Combiner 5/5C, COMMS-KIT-02, and IQ6/IQ7/IQ8 (M Series only where IEEE 1547:2018 is not yet adopted).
- Approved for use as service equipment in the United States; not suitable as service equipment in Canada per the datasheet footnote.
- Professional installation required. Follow Enphase instructions and the NEC.
