3ph Accs.

The Enphase 3ph IQ Relay is a physical disconnection device relay controller. It is designed for three-phase use and has built in contactors.

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 microinverters to the AC grid. The Q Relay has built in current sensing that can detect DC current injection required by VDE V 0126-1-1 requirements. 

The Q Relay works together with the Envoy-S to meet the need to break both line and neutral per grid requirements. See full installation instructions for the Enphase Envoy-S and/or Enphase Microinverters at: enphase.com/support. It is best practice to install the Q Relay when installing the Envoy-S and before commissioning the system. The Q relay is IP-20 rated. You must mount it in an environmentally protected enclosure.

Not required in the UK.
