Enphase Microinverters are FCC Part 15, class B compliant. The Enphase Microinverter converts a DC input voltage to AC output voltage at each solar module. All power electronics generate some amount of electronic interference and Enphase has worked very hard to minimize the amount of interference that originates from the microinverter. However, interference may occur when sensitive antennas are mounted near the Enphase system. If you are experiencing some interference, move your antenna to a point further from your solar array.
