IQ Relay (three-phase)

In the Enphase Energy System, the three-phase IQ Relay acts as a device for network monitoring and isolation. It contains an integrated phase coupler for distributing the communication signals across power lines for the different phases. With the three-phase IQ Relay, no external phase coupler is required. The IQ Relay physically disconnects IQ Series Microinverters from the grid when anomalies are detected or when grid regulations require it. The connection is automatically re-established as soon as the relevant grid conditions are met again.
