Technical Data

Technical Considerations

The Siemens SMIINV215R60XX Microinverters are designed to operate 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 the Siemens website
(http://www.usa.siemens.com/microsolar) for a list of compatible PV module racking systems and
PV modules.
WARNING: You must match the DC operating voltage range of the PV module with the
allowable input voltage range of the Siemens Microinverter.
WARNING: The maximum open circuit voltage of the PV module must not exceed the
specified maximum input voltage of the Siemens 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 solar insolation on each cell. The highest PV module output voltage
occurs when the temperature of the cells is the lowest and the module is at open circuit (not
operating). The maximum short circuit current rating of the module must be equal to or less than
the maximum input DC short circuit current rating of the microinverter.
A list of compatible PV modules is maintained on the Siemens website
(http://www.usa.siemens.com/microsolar).
