308

Intermediate circuit voltage too high

Fronius · Primo GEN24 Operating Instructions

Hva betyr 308 ?

This code indicates that the intermediate DC bus voltage within the inverter has exceeded its permissible upper limit. This causes a short-term interruption in energy feeding, after which the inverter will attempt to resume its startup routine.

Vanlige årsaker

  • Excessive DC input voltage from the PV array, potentially due to incorrect string sizing or open circuit conditions.
  • Grid overvoltage causing DC bus voltage to rise.
  • Malfunction in the inverter's DC-DC converter or control circuitry.

Reparasjonssteg & Sjekkliste

Klikk på steg for å spore fremgangen.

  1. 1

    If this status code keeps recurring, contact your system engineer for diagnosis.

  2. 2

    Verify the PV string configuration and open-circuit voltage (Voc) to ensure it is within the inverter's specified DC input range.

  3. 3

    Measure the DC bus voltage at the intermediate circuit to verify actual voltage levels.
