#1: Q-RELAY-3P-INT

Enphase Three-Phase Q Relay (Network System Relay Controller)

Product Overview

The Enphase Three-Phase Q Relay is a galvanic disconnection device designed to protect your solar PV system by safely disconnecting Enphase Microinverters from the AC grid during specified grid abnormalities. It works in conjunction with the Enphase Envoy-S to ensure compliance with grid requirements, including breaking both line and neutral connections.

This relay is ideal for single-phase use and includes built-in contactors and current sensing, meeting the VDE V 0126-1-1 standards for DC current injection detection.

Note: The Q Relay is IP20 rated and must be mounted inside an environmentally protected enclosure.
