Technical Data
Technical Considerations
The Enphase M215 Microinverters are electrically compatible with most 60-cell PV modules. Be sure to
verify the voltage and current specifications of your PV module match those of the microinverter. For
more information, refer to our list of compatible PV modules at http://www.enphase.com/support.
WARNING: You must match the DC operating voltage range of the PV module with the
allowable input voltage range of the Enphase Microinverter.
WARNING: 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.
