Technical data
Technical considerations
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 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" to comply with NEC for
ungrounded PV power systems.
•
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 insolation of 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).
Bifacial modules
Enphase microinverters are compatible with bifacial PV modules. Bifacial solar modules produce
power from both sides of a bifacial module, increasing total energy generation. The power gained
from the rear side (bifacial gain) is highly influenced by various design factors such as albedo,
module elevation, pitch, temperature, and shading. The bifacial gain can be anywhere between
0% to 30% of the nominal rating (front-side power rating) of the module. Since the bifacial gain is
highly influenced by various design considerations, pairing the bifacial module with the right
microinverter depends on the electrical characteristics of a given module.
