3-Phase Enphase Q Relay

Manufacturer Number: Q-RELAY-3P-INT

Reliable Grid Protection for 3-Phase Enphase Systems

The Enphase Q Relay (3-Phase) is a mechanical relay designed to disconnect the PV system from the power grid whenever the grid voltage or frequency falls outside the specified limits.
It ensures the PV installation complies with the VDE-AR-N 0126-1-1 standard for grid safety and disconnection requirements.

Key Features

• Designed for three-phase Enphase systems.

• Automatically disconnects the solar installation from the grid during abnormal conditions.

• Installed directly after the PV system’s circuit breaker for maximum safety.

• Integrated phase coupler, eliminating the need for a separate coupling device.

• Ensures full compliance with VDE 0126 and other relevant safety standards.

System Compliance

While the PV system can technically operate without the Q Relay, it would not comply with grid connection regulations. The 3-phase Q Relay is therefore an essential component for all Enphase installations requiring certified grid protection.
