2 IQ8 Commercial system design considerations

2.1 IQ8 Commercial Microinverters

The high-powered, smart-grid-ready IQ8 Commercial Microinverter is an advanced
microinverter. Each IQ8 Commercial Microinverter supports one PV module and has greater than
97% CEC efficiency for three-phase 208 V applications with peak output power ratings of 384
and 480 watts.
IQ8 Commercial Microinverters have an output configuration of a 4-pin (L1, L2, L3, and N) AC
connector with power on two pins and phase sensing on the other two pins. Three-phase
configuration and phase balancing are achieved using the three-phase QD Cable. The following
topics describe the design considerations for IQ8 Commercial Microinverters.
2.1.1

Module compatibility

The Enphase IQ8 Commercial Microinverters are electrically and mechanically compatible with
PV modules, as listed in Table 2. To verify PV module electrical compatibility with IQ8 Commercial
Microinverter, refer to the Enphase Compatibility Calculator at
us/support/module-compatibility.
