6. Technical data
6.1 Technical considerations
Be sure to apply the following when installing the Enphase IQ8 Series Microinverters
System:
WARNING: Risk of equipment damage. You must match the DC operating voltage range of the
PV module with the allowable input voltage range of the Enphase microinverter.
WARNING: Risk of equipment damage. The maximum open circuit voltage of the PV module
must not exceed the specified maximum input voltage of the Enphase microinverter.
PV modules must have conductors labeled "PV Wire" or "PV Cable".
Verify that the voltage and current specifications of the PV module match those of the
microinverter.
The maximum short circuit current rating of the PV module must be equal to or less than the
maximum input DC short circuit current rating of the microinverter.
The output voltage and current of the PV module depend on the quantity, size, and temperature of the
PV cells, as well as the insulation on each cell. The highest PV module output voltage occurs when the
temperature of the cells is the lowest, and the PV module is at an open circuit (not operating).
6.2 Bifacial modules
Enphase IQ8 Series Microinverters are compatible with bifacial PV modules if the temperature-
adjusted electrical parameters (maximum power, voltage, and current) of the modules, considering the
electrical parameters, including the bifacial gain, are within the allowable microinverter input
parameters range. In evaluating the amount of bifacial gain, follow the recommendations of the
module manufacturers.
