    In Enphase IQ installations, the multiphase Q Relay acts as a grid monitoring and disconnection device and includes a built-in phase coupler to distribute power line communication signals across phases. An external phase coupler is not needed when the Q Relay is installed. The Q Relay physically isolates the IQ Series Microinverters from the grid when abnormalities are sensed or as required by grid regulations, and it automatically reconnects when valid grid conditions resume.

    The 4-pole Q Relay isolates all phase and neutral lines and works together with the Enphase Envoy-S gateway
