Product information
The Enphase external relay for the IQ Series (three-phase version) is required to connect Enphase microinverters in a three-phase solar system. Besides acting as a relay, it also works as a phase coupler, enabling communication between the system's three phases.
The device is installed in the PV box or the meter box on the solar side. Note: in the three-phase version, the grid connects at the bottom and the PV system at the top (it is the reverse in the single-phase variant).
