Enphase Relay Q (3-phase)

Enphase Relay Q (multiphase)

In Enphase IQ installations, the multiphase Q Relay functions as a grid monitoring and disconnecting device.
The Q Relay physically isolates IQ series microinverters from the grid when anomalies are detected or in accordance with grid regulations, and automatically reconnects when valid grid conditions are restored.
The Tetrapolar Q Relay isolates all phase and neutral conductors, and works in conjunction with the Envoy-S gateway.
