Technical Data

Technical Considerations

PV modules paired with the C250 must have conductors labeled "PV Wire" or "PV Cable" to be compliant
with NEC 690.35(D) for Ungrounded PV Power Systems. Be sure to verify the voltage and current
specifications of your PV module match those of the microinverter.
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.
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). 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.
