About product

The Enphase Three-Phase Network Protection Relay comes together with Enphase IQ Envoy and Enphase Mobile Connect modem. The three constitute a ready-to-use solution for commercial three-phase 208 VAC solar panel systems. IQ Microinverters can function without the Network Protection Relay, however, it may be required by utilities or AHJs in accordance with IEEE 1547. The device constantly tracks the voltages to detect loss of phase. In case of abnormalities it disrupts the powerflow and automatically reconnects later.


  • The network protection relay and contactor are built in
  • Compact size and pre-wired components
  • Installation is easier with a backplate
  • Cable entries and exits are customizable
  • Up to 200 A input (AC)


  • Compatibility with three-phase 208 VAC systems employing IQ 7 Series microinverters
  • IQ Envoy allows to communicate with and control your PV system
  • Phase-wise performance tracking is possible with optional CTs
  • Wi-Fi, Ethernet, or cellular networking options


  • NEMA 3R enclosures
  • Five year warranty
  • UL 1741 SA compliant

CT-200-SPLIT enables consumption metering. Three of them are needed for this device.
