Description
In Enphase IQ installations, the multi-phase IQ Relay acts as grid monitoring and a disconnecting device, and includes a built-in phase coupler to distribute powerline communication signals across phases. If the IQ Relay is installed, an external phase coupler is not needed. The IQ Relay physically isolates IQ Microinverters from the grid when faults are detected or when 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 together with the Enphase Gateway-S.
