3PH Enphase Q Relay INT

In Enphase IQ installations, the multi-phase IQ Relay acts as a network monitor and disconnection device, and includes a built-in phase coupler for distributing communication signals in power cables between the phases. An external phase coupler is not required when the IQ Relay is installed. The IQ Relay physically disconnects the IQ Microinverters from the grid when abnormalities are detected or when required by grid regulations, and automatically reconnects when the grid condition is again suitable.
