Enphase Relay Controller 20A F/1 ph System

In enphase installations, the Q relay (network system relay controller) acts as a physical disconnection device relay controller for 1-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 Relay reconnects the system. The Q relay works with the Envoy-S to break both line and neutral, when needed, per grid requirements. This product has a warranty of 5 years.
