Product Overview
The Enphase IQ Combiner 5 with factory-installed hold-down kit (X-IQ-AM1-240-5-HDK) consolidates interconnection equipment into one outdoor enclosure and includes an IQ Gateway PCB for production, consumption, and IQ Battery metering.
It supports up to four 2-pole branch circuits for IQ Series Microinverters and is listed for use with IQ System Controller 3/3G and IQ Battery 5P on the Americas datasheet. Wired CTRL communication is built in.
Best For
- Residential Enphase Energy Systems that need a combined PV branch center plus metered IQ Gateway in one NEMA 3R enclosure.
- Projects specifying the HDK SKU: When a factory-installed hold-down kit is wanted (no separate X-IQ-NA-HD-125A needed, per the datasheet).

What You May Also Need
Usually required
- Disconnects & Breakers: Correctly sized 2-pole branch breakers for PV (and storage if used) per the datasheet accessory list.
- Internet connection (Wi-Fi, Ethernet, or optional cellular modem) for Enphase Cloud monitoring.
May be required
- CTRL-SC3-NA-01 control cable for wired CTRL to IQ System Controller 3/3G and IQ Battery 5P.
- IQ System Controller 3 or IQ System Controller 3G when the system includes backup.
Optional upgrades
- Enphase Mobile Connect cellular modem (CELLMODEM-07-NA-05 and related SKUs), ordered separately, if cellular is required and not already on site.
- Combiner Boxes: Compare other Enphase combiners on the same collection.
Check current manufacturer documentation before combining components, especially batteries, inverters, communications equipment and system-control hardware.
Important Considerations
- Americas datasheet Compatibility table lists IQ6, IQ7, and IQ8 Series Microinverters; IQ System Controller 3/3G (SC200D111C240US01 / SC200G111C240US01); and IQ Battery 5P. IQ Battery 3/10/3T/10T and IQ System Controller 1/2 (formerly Encharge/Enpower) use COMMS-KIT-01 per the datasheet footnotes — confirm the matrix for your battery generation.
- The IQ Combiner 5/5C quick install guide (version 12.0, April 2026) states it is not compatible with M Series Microinverters, and requires COMMS-KIT-01 for IQ Battery 3/10/3T/10T and IQ System Controller 1 or 2.
- Do not treat this SKU as IQ Combiner 5C: the 5C variants include Enphase Mobile Connect; X-IQ-AM1-240-5-HDK does not list a factory cellular modem.
- Professional installation required. Follow Enphase instructions and the NEC.
