Module Compatibility Calculator

Use this calculator to help determine the electrical compatibility of PV modules with the Enphase microinverter family. Refer to the PV module manufacturer's datasheet for correct values. All fields are required.

Solar Module Information

Voc (Voltage at Open Circuit)

The Voc is the voltage that is read with a voltmeter or multimeter when the module is not connected to any load.

V

Please provide a valid number.

Vmp (Voltage at Maximum Power)

The Vmp is the voltage that is read with a voltmeter or multimeter when the module is producing maximum power.

V

Please provide a valid number.

Temperature Coefficient of Voc

Coefficient used to determine effect of temperature on a PV module's open circuit voltage. Contact your manufacturer if this value is not listed on the datasheet.

-

Please provide a valid number.

Isc (Short Circuit Current)

This is the amount of current that flows through the electrical leads when shorted--essentially the maximum amount of current that the PV module can source.

A

Please provide a valid number.

Expected temperature range

Enter the LOWEST daytime temperature and the highest AVERAGE temperature when sunlight will be on the array. The ASHRAE Handbook is the recommended source for weather data in a particular location or you can look up the Extreme Low temperatures for your location by clicking here.

Notice

The Enphase microinverter family can be paired with 60-cell and 72-cell PV modules that match appropriate specifications. Do not connect an Enphase microinverter to a module that the calculator indicates is incompatible. A module should not exceed the maximum input DC voltage of the specific Enphase microinverter model or the maximum current. Doing so may void the warranty. Refer to microinverter datasheet information provided on the product page.. The compatibility calculator does not take into account performance considerations such as PV DC/INVERTER AC ratio which should be considered the system designer.
