Enphase Replacement DC Adapter to MC4 – Q-DCC-2
SKUQ-DCC-2
The Enphase Q-DCC-2 is listed in the Americas IQ Cable accessories datasheet as "Replacement DC adapter (MC4)" — a DC adapter to MC4 with a maximum voltage of 100 VDC. The same datasheet lists a separate model, Q-DCC-2-P, for IQ8P Microinverters.

Product Overview
The Enphase Q-DCC-2 is listed in the Americas IQ Cable accessories datasheet as "Replacement DC adapter (MC4)" — a DC adapter to MC4 with a maximum voltage of 100 VDC. The same datasheet lists a separate model, Q-DCC-2-P, for IQ8P Microinverters.
Use it only where current Enphase documentation names Q-DCC-2 for the unit on the job. Units with EN4 DC ports use the ECA-EN4 adapter family listed on the same datasheet.
Best For
- Replacement MC4 DC adapter where Enphase specifies Q-DCC-2: Restoring or replacing the DC adapter cable on a supported IQ Series unit.
- Service stock for Q-DCC-2 ports: Not a substitute for EN4-to-MC4 adapter families (ECA-EN4-…) or for Q-DCC-2-P.

What You May Also Need
Usually required
- The Enphase IQ Series unit whose documentation names Q-DCC-2.
May be required
- Q-DISC-10: Disconnect tool for DC connectors (Enphase datasheet DSH-00247-1.0).
Optional upgrades
- Cable & Wiring: IQ Cable accessories for the AC side of the same array.
Check current manufacturer documentation before combining components, especially batteries, inverters, communications equipment and system-control hardware.
Important Considerations
- Do not assume Q-DCC-2 fits every IQ Series model. The same datasheet lists Q-DCC-2-P for IQ8P and ECA-EN4 adapters for EN4 ports.
- Never disconnect the DC connectors under load (Enphase Q Cable Terminator guide safety instructions).
- No ampacity is stated for Q-DCC-2 on DSH-00247-1.0; use the ratings in the current microinverter documentation for the installed unit.
