    What does Abnormal Residual Current mean on Huawei Inverter?
    • P
      Patricia BlackSep 1, 2025
      If your Huawei Inverter indicates an Abnormal Residual Current, it means the insulation impedance of the input side to PE decreases when the SUN2000 is operating. If the alarm occurs occasionally, the external circuit may be abnormal temporarily and the SUN2000 will automatically recover after the fault is rectified. However, if the alarm occurs frequently or persists, check whether the impedance between the PV string and the ground is too low.

    What does Output DC Component Overhigh mean on Huawei 01075345?
    • S
      Sherry ElliottSep 1, 2025
      If your Huawei Inverter displays an Output DC Component Overhigh alarm, it means the DC component of the SUN2000 output current exceeds the specified upper threshold. The SUN2000 detects its external working conditions in real time and automatically recovers after the fault is rectified.

    What to do if Huawei Inverter showing Faulty Power Collector?
    • J
      Joshua MannSep 3, 2025
      If your Huawei Inverter is showing a Faulty Power Collector message: * Check that the configured power meter model is the same as the actual model. * Check that the communications parameters for the smart power sensors are the same as the SUN2000 RS485 configurations. * Check whether the smart power sensor is powered on and whether the RS485 communications cable is connected.

    What does Battery Abnormal mean on my Huawei 01075345 Inverter?
    • C
      Christopher ScottSep 3, 2025
      If your Huawei Inverter displays a Battery Abnormal message: * If the battery fault indicator is steady on or blinking, contact the battery supplier. * Check that the battery enabling/power/ communications cable is correctly installed, and that the communications parameters are the same as the SUN2000 RS485 configurations. * Check that the auxiliary power switch on the battery is set to ON. * Send a shutdown command on the app. Turn off the AC output switch, DC input switch, and battery switch. Then turn on the battery switch, AC output switch, and DC input switch in sequence after 5 minutes.

    What does Off-grid output overload mean on Huawei 01075345?
    • S
      slutzSep 4, 2025
      If your Huawei Inverter displays an Off-grid output overload, it means the output is overloaded or short-circuited. Check whether the device output is short-circuited and whether the device load configuration exceeds the rated value.

    What does Abnormal PV Module Configuration mean on Huawei 01075345 Inverter?
    • J
      James HarperSep 5, 2025
      If your Huawei Inverter displays an Abnormal PV Module Configuration, it means the PV module configuration does not meet requirements, or the PV module output is reversely connected or short-circuited. Check whether the total number of PV modules, number of PV modules in a string, and number of PV strings meet requirements and whether the PV module output is reversely connected.

    What does Grid-tied/Off-grid Controller Abnormal mean on Huawei 01075345 Inverter?
    • M
      michael46Sep 5, 2025
      If your Huawei Inverter displays a Grid-tied/Off-grid Controller Abnormal message, it indicates that the inverter fails to communicate with the Smart Backup Box. Send a shutdown command on the app. Turn off the AC output switch, DC input switch, and battery switch. Check whether the power cable and RS485 cable between the Smart Backup Box and the inverter are normal. After 5 minutes, turn on the battery switch, AC output side, AC output switch, and DC input switch.

    What to do if my Huawei Inverter displays Grid Overvoltage?
    • M
      Matthew ChandlerSep 6, 2025
      If your Huawei SUN2000 Inverter is showing a grid overvoltage alarm: 1. If the alarm occurs occasionally, it might be due to a temporary power grid abnormality. The SUN2000 will automatically recover once the grid returns to normal. 2. If the alarm is frequent, verify that the power grid voltage is within the acceptable range. If it's outside the range, contact your local power operator. If it is within range, with the consent of the local power operator, adjust the grid overvoltage protection threshold using the mobile App, SmartLogger, or NMS. 3. Also, check for peak voltage issues on the power grid and if the problem persists, contact the power operator.
