New integrated
MC4 connectors.

Micro EU

Updated IQ 7+ microinverters are now available.

Enphase installs just got easier with integrated MC4 connectors for IQ 7+.
Say goodbye to adapter cables and enjoy an easier workflow for your team.
No adapter cable required.

Connect solar modules directly into microinverters without an adapter cable.

Faster installation.

Simplify inventory on the truck and reduce unnecessary connections on the roof.

Maximum reliability.

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

One less step.

Without the adapter cable, you have one less connection for every solar module. This simple update
results in fewer connections for a typical residential install and thousands less for your team over time.
It also means fewer parts that you need to carry up the ladder to the roof.

New IQ 7 with integrated MC4 connector and no adapter cable.

New microinverter model numbers.

During the transition phase, please refer to the graphic below to know when a Q-DCC-2 adapter cable
is required for a given microinverter. Model numbers with a “2” include the required Q-DCC-2
adapter cable, while those with an “M” have an integrated MC4 connector.

Frequently asked questions

Data sheets coming soon.

Microinverters with integrated MC4 connectors will no longer ship with a Q-DCC-2 adapter cable as they are no longer necessary.

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

We are gradually transitioning IQ 7 series microinverters to these new designs. IQ 7+ will be the first to transition to an integrated MC4 connector, followed by the IQ 7 and IQ 7A. We expect all IQ series microinverters to be updated by the end of 2022

The table below lists SKU numbers for existing microinverters (with adapter cables) and their equivalent with integrated MC4 connectors.

Exisiting product # New product #

Yes, you can mix and match microinverters as long as they are the same product line. For example, an IQ 7+ with an integrated MC4 connector can be combined with an IQ 7+ that still uses a Q-DCC-2 adapter. Note that the permit should use an “X” in place of either the “2” or “M” as stated above to avoid any inspection issues.

No, there is no price difference between the two types.

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 1.2 to 1.8 meters in length.

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