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.
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 | |||

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.
