Use the updated Enphase compatibility calculator to determine the electrical compatibility of PV modules with the Enphase IQ Microinverters.
All IQ8 Series Microinverter documentation has been updated with the new specifications outlined above. Visit the documentation center to view these technical documents.
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.

No, there is no price difference between the microinverters that have integrated MC4 connectors and those that use adapter cables.
It doesn't use an external bulkhead adapter, so the overall cable is a bit less. However, module leads are typically 4 to 6 feet long, so the impact is minimal.
Yes, all microinverters will eventually have integrated MC4 connectors. We are gradually transitioning each inverter in a phased manner.

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 be shipped with a Q-DCC-2 adapter cable, as they are no longer necessary.
