Frequently asked questions
What differentiates the existing IQ8M, IQ8A, and IQ8H Microinverters from the new IQ8MC, IQ8AC, and IQ8HC Microinverters?
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) |
