¿Qué significa 3901/3902 ?

The necessary feed-in conditions for the utility grid have not yet been fulfilled, preventing the inverter from starting operation. This is often related to environmental conditions or initial setup parameters.

Causas comunes

  • PV array is covered by snow or otherwise shaded, reducing power output.
  • Insufficient solar irradiation to meet minimum operating thresholds.
  • The voltage limit for starting grid feed-in is set too high (parameter `Critical voltage to start feed-in`).
  • PV array is incorrectly rated for the inverter's start-up requirements.

  1. 1

    Ensure that the PV array is not covered by snow or otherwise shaded.

  2. 2

    Wait for higher solar irradiation levels.

  3. 3

    If this message is displayed frequently in the morning, increase the voltage limit for starting grid feed-in by changing the parameter `Critical voltage to start feed-in`.

  4. 4

    If this message is displayed frequently with medium irradiation, ensure that the PV array is correctly rated for the inverter.
