Integrated MC4 connectors
for easier installs


Say goodbye to adapter cables and enjoy a simpler workflow for your team

No adapter cable required

Connect solar modules directly into microinverters without an adapter cable.

Faster installation

Streamline truck inventory and reduce unnecessary connections and parts on the roof.

Maximum reliability

Reduce the likelihood of issues down the road with fewer connections.

One less step

With the MC4 connectors, you can eliminate the adapter cable, reducing the number of connections your team will complete over the years by the thousands. It also means fewer parts that you need to carry up the ladder to the roof.

New IQ Microinverter with integrated MC4 connector, eliminating the adapter cable

Model numbers and availability

As you’re ordering Enphase IQ Microinverters, please use our reference tables as a guide to know when a Q-DCC-2 adapter cable is required. At a glance, model numbers that include “2” will require the adapter cable. Model numbers that include “M” will have an integrated MC4 connector.

Frequently asked questions

Enphase recommends installers submit Enphase microinverter model numbers on permits and plan sets using an “-x” in place of either the “-2” or “-M”, and add “where x = 2 or M.”

For example: “Model Number: IQ7-60-x-US, where x = 2 or M” or “IQ8PLUS-72-x-US, where x = 2 or M.”

Microinverters with integrated MC4 connectors will not ship with a Q-DCC-2 adapter cable as they are no longer necessary.

There are no special instructions for microinverters with integrated MC4 connectors. Please follow the same installation practices as outlined in the Enphase installation manual.

This table lists the existing product SKU numbers and their equivalent integrated MC4 connector counterparts.

Yes, you can mix and match microinverters as long as they are in the same product line. For example, an IQ7+ with an integrated MC4 connector can be combined with an IQ7+ that still uses a Q-DCC-2 adapter. Note that the permit should use an "-x" in place of either the “-2” or “-M”, and add “where x = 2 or M.”

For example: “Model Number: IQ7-60-x-US, where x = 2 or M" or “IQ8PLUS-72-x-US, where x = 2 or M.”

No, there is no price difference between the microinverters that have integrated MC4 connectors and those that use adapter cables.

Because we are eliminating the external bulkhead adapter, there is slightly less total cable. However, the impact should be minimal as module leads are typically 4–6 ft in length.

Yes, all microinverters will eventually have integrated MC4 connectors. We are gradually transitioning each inverter in a phased manner.
