Problem

  • No Display on Screen

    • Cause: DC power switch Q1 is off. Insufficient irradiation. Broken strings. Internal malfunction.

  • Fan Fault 1…9

    • Cause: The indicated fan is defective.

  • Temperature Limit

    • Cause: The feed-in power is temporarily reduced because the radiator temperature has reached 80°C.

  • Temperature Sensor Fault

    • Cause: A temperature sensor of the inverter is defective.

  • DC Insulation Error

    • Cause: Short circuit in the PV generator to the ground. Faulty wiring of the PV generator. High leakage currents in the PV generator due to moisture.

  • Ief Too High

    • Cause: The ground leakage current of the Potential Equalization Set (PAS) is too high (the message is displayed only in the case of PAS usage). There is an insulation error in the PV generator.

  • PAS Fuse Broken

    • Cause: The fuse in the PAS is broken (the message is displayed only in the case of PAS usage).

  • MaxConnect Warning

    • Cause: A malfunction has occurred in the generator connection box (the message is displayed only if MaxConnect is connected to the inverter via alarm contact).

  • Vdc Too High

    • Cause: The DC input voltage of the inverter is too high (see "Technical Data" chapter).

  • AC Currents Asymmetric

    • Cause: The differences between the individual phase currents are too high.

  • No Grid

    • Cause: AC power switch Q2 is off. No grid voltage is present or the AC supply is interrupted.

  • Grid Error

    • Cause: The grid has been switched off.

  • Frequency Too High / Too Low

    • Cause: The grid frequency is outside the tolerance range.

  • Vac Too High / Too Low

    • Cause: The grid voltage is outside the tolerance range.

  • Wrong Rotation Sense

    • Cause: The rotation direction of the connected grid phases is wrong.

  • Vac 10 Min Too High

    • Cause: The 10-minute average value of the grid voltage is too high.

  • Temp Too High

    • Cause: The ambient temperature is too high. Insufficient air circulation or fresh air intake.

  • DC Insulation Error

    • Cause: Short circuit in the PV generator to the ground. Faulty wiring of the PV generator. High leakage currents in the PV generator due to moisture.

  • Overvoltage / Overcurrent

    • Cause: Overvoltage / overcurrent in the inverter's power supply.
