Relay Controller 3PH V/FRT &/or DCI Compliance for IQ Invert

Relay controller for V/FRT and/or DCI compliance in countries requiring mechanical PV disconnect when using IQ microinverters. This device contains three contactors rated to interrupt the PV system ampacity

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.
