Technical Considerations

Be sure to apply the following when installing the Enphase IQ 7 and/or IQ 7+ Micro 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" 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 depends on the quantity, size and temperature of the
PV cells, as well as the insolation 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 open circuit (not operating).
