Enphase IQ Relay Single-Phase/Three-Phase

In Enphase IQ installations, the multi-phase IQ Relay serves as a grid monitor as well as a disconnection device and includes an integrated phase coupler to distribute power line communication signals across phases. If an IQ Relay is installed, an external phase coupler is not necessary. The IQ Relay physically isolates the IQ Microinverters from the grid when faults are detected or as required by grid regulations, automatically reconnecting them when valid grid conditions are restored. The 4-pole IQ Relay isolates all phase and neutral lines and works in conjunction with the Enphase Gateway-S.
