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.
Due to the rapidly changing PV module landscape, we are witnessing an emergence of PV modules with higher DC output currents. Currently, M10 wafer-based PV modules are the most prevalent in the market. The DC output current of these modules ranges from 13 A to 14 A at standard test conditions (STC). IQ8MC, IQ8AC, and IQ8HC Microinverters with a maximum continuous DC input current of 14 A are ideally suited for these higher-current modules.

All these SKUs support 240 V-split-phase (L-L), 180° grids in a single-phase/split-phase and 208 V-single-phase (L-L), 120°connection.
Yes, all microinverters will eventually have integrated MC4 connectors. We are gradually transitioning each inverter in a phased manner.
Yes, IQ8MC, IQ8AC, and IQ8HC Microinverters can be used in the same system and branch along with the IQ8, IQ8+, IQ8M, IQ8A, IQ8H-240, and IQ8H-208 Microinverters. Moreover, these microinverters can be connected to the same IQ Gateway.
Yes. IQ8MC, IQ8AC, and IQ8HC Microinverters support 240 V split-phase and 208 V single-phase in the United States. Check the respective data sheets for more information.

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.
