Description

Enphase Q-Relay for IQ7 & IQ8 Series Single Phase

The Enphase Q-Relay (Q-RELAY-1P-INT) is a critical component in single-phase Enphase microinverter systems, acting as a galvanic isolation relay. It ensures safe and compliant disconnection of microinverters from the AC grid during grid abnormalities and automatically reconnects when conditions return to normal. Specifically designed for use with IQ7 and IQ8 Series Microinverters, the Q-Relay meets European grid standards, including the VDE V 0126-1-1 requirement for DC current detection. Compact and efficient, it is installed in conjunction with the Envoy-S and must be housed within a protected enclosure.
