    IQ8P Microinverters over on-site AC power lines and transmits the data to Enphase App through a broadband or cellular connection. The IQ Gateway is capable of monitoring up to 300 IQ8P Microinverters and up to 20 IQ Batteries. For details, refer to Enphase IQ-Gateway Installation and Operations Manual.

    65°C (149°F). Ease of design PV systems using Enphase microinverters are very simple to design and install. You will not need to perform cumbersome string sizing calculations like conventional string inverters. You can install individual PV modules in any combination of PV module quantity, type, age, and orientation. Each microinverter quickly mounts on the PV racking, directly beneath each PV module.
  • Page 11: Compatibility

    IMPORTANT: The IQ8P Microinverters include both AC and DC connectors integrated into the bulkhead. The AC port connects to IQ Cable or Enphase Field Wireable Connector. The DC port has been evaluated by TUV for intermateability with Stäubli made MC4 connectors, whose cable coupler models are “PV-KST4/…-UR, PV-KBT4/…-UR, PV-KBT4-EVO2/…-UR, and PV-KST4-EVO2/…-UR”.
  • Page 12: Electricity Network Requirements

    Select the correct conductor size based on the distance from the junction with the microinverter AC branch circuit to the circuit breaker in the electrical panel. Enphase recommends a voltage rise total of less than 2% for the sections from the microinverter AC branch circuit to the circuit breaker in the electrical panel.

    You can set the grid profile through the Enphase Installer Platform, during system registration, or through Enphase Installer App at any time. You must have an IQ Gateway to set or change the grid profile. For more information on setting or changing the grid profile, refer to the IQ Gateway Installation and Operation Manual at https://enphase.com/en-za/installers/resources/documentation.
  • Page 22: Dc Resistance Low - Power Off Condition

    DC Resistance Low – Power Off condition For all IQ8P Microinverters, a solid red status LED when DC power has been cycled indicates the microinverter has detected a DC Resistance Low – Power Off event. The LED will remain red, and the fault will continue to be reported by the gateway until the error has been cleared.
