Product description

In Enphase systems, the IQ Relay (NA Protection) acts as a physical grid disconnection device in multi-phase PV installations. It has an integrated phase coupler to transfer the PLC signals to all phases. The 4-pole IQ Relay disconnects all phase conductors as well as the neutral conductor. It operates in conjunction with the Enphase IQ Gateway Metered communication gateway (08-000663).
