Enphase Q Relay – three phase
Q RELAY THREE PHASE
Relay controller for voltage/frequency compliance for three-phase systems
In Enphase installations, the Q Relay (network system relay controller) acts as a physical disconnection device relay controller for single-phase installations.
During specified grid abnormalities, the Q Relay disconnects the Enphase Microinverters from the AC grid, and when the voltages return to normal and the grid frequency is in the acceptable range, the Q Relayreconnects the system.
The Q Relay works in series with the Envoy-S to break both line and neutral, when needed, per grid requirements.
Easy to Install
• Lightweight and simple
• DIN rail mount for quick installation
• Dependable load control
• Automatically resets when normal voltage resumes
• Performs voltage and frequency ride-through• Remote upgrade capability
• Easy to read LEDs
