Technical data

Be sure to apply the following when installing the Enphase IQ8 Series Microinverter 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

modules must not exceed the specified maximum input voltage of the microinverters.

Verify that the voltage and current specifications of the PV modules match those of the

microinverters.

The maximum short circuit current rating of the PV modules must be equal to or less than the

maximum input DC short circuit current rating of the microinverters.

The output voltage and current of the PV modules 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).

IQ8 Series Microinverter is 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.

IQ8 Series Microinverter complies with anti-islanding requirements as per AS4777.2, and the method

used is VAR injection with frequency bias.
