Enphase Three-phase Q Relay

Enphase’s three-phase Q Relay is smart, reliable, lightweight and easy to install. The Enphase Q Relay is an essential component for the safety of your PV system. The three-phase Q Relay electronically isolates three-phase Enphase IQ systems and features built-in circuit breakers. The Q Relay will disconnect the Enphase microinverters from the AC grid in response to a power grid fault and automatically reconnect the system when the voltages and mains frequency return to normal levels. The Q Relay will communicate with the Envoy-S to disconnect line and neutral conductors based on the network requirements.

The mains power supply must be disconnected before connecting the wiring to prevent the risk of electric shocks. Both LEDs should turn green after installing and switching on the device (this indicates that the AC voltage and frequency meet the network code requirements).
