Modules paired with Enphase microinverters with Integrated Ground must use PV Wire or PV Cable that is compliant with NEC 690.35(D) for Ungrounded PV Power Systems. When using this solar panel calculator, do not connect an Enphase microinverter to a module that the calculator indicates is incompatible. Doing so may void the warranty. This calculator only shows the compatibility of the modules with Enphase microinverters and doesn’t provide any information on clipping that may occur due to sizing and other DC parameters of the PV module. Enphase IQ Series microinverters are compatible with bi-facial PV modules if the temperature adjusted electrical parameters (maximum power, voltage and current) of the modules, considering the electrical parameters including the Bifacial gain, are within the allowable microinverter input parameters range. In evaluating the amount of Bifaciality gain, follow the recommendations of the module manufacturers.
