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.
The following tables illustrate the differences in DC and AC parameters between these microinverter models. Refer to the table below for DC parameter changes:
| DC parameters | IQ8M | IQ8MC | IQ8A | IQ8AC | IQ8H | IQ8HC |
| MPPT voltage range (V) | 30-45 | 25-45 | 32-45 | 28-45 | 36-45 | 29.5-45 |
| Operating range (V) | 16-60 | 18-60 | 16-60 | 18-60 | 16-60 | 18-60 |
| Max. cont. operating DC (A) | 12 | 14 | 12 | 14 | 12 | 14 |
Apart from this, the maximum continuous power of the IQ8MC Microinverter is reduced by 5 W to accommodate one extra microinverter in a branch (peak power remains the same for the IQ8M and the IQ8MC). Refer to the table below for AC parameter changes:
| AC parameters | IQ8M | IQ8MC | IQ8A | IQ8AC | IQ8H | IQ8HC |
|---|---|---|---|---|---|---|
| Max. cont. output power @240 V (W) |
325 | 320 | No change | |||
| Max. units per 20 A (L-L) branch circuit @240 V |
11 | 12 | No change | |||
| Supports 208 V grid (single-phase) |

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.
