What to do if Huawei Network Hardware shows External fan abnormal?
- S
  Shelley StoneSep 23, 2025
  If your Huawei Network Hardware reports an External fan abnormal error, it could be due to the fan being short-circuited, insufficient power supply, or a blocked air channel. To troubleshoot: 1. Shut down the fan, turn off the DC switch, check whether the fan blades are damaged, and clear any foreign matter around the fan. 2. Reinstall the fan, turn on the DC switch, and wait for the inverter to start. If the fault persists after 15 minutes, replace the external fan.

How to fix Huawei Network Hardware String Reversed error?
- S
  Shannon ChavezAug 25, 2025
  If your Huawei Network Hardware displays a String Reversed error, first check if the PV string is connected with reverse polarity. If it is, wait for the PV string current to drop below 0.5 A, then set the DC SWITCH to OFF and correct the PV string polarity. If the problem continues, try resetting the device using the local maintenance app or the WebUI of the upper-layer controller. Alternatively, power down the device by turning off both the AC and DC switches for 5 minutes, and then turn them back on.

What to do if my Huawei Network Hardware has a Grid Overvoltage?
- T
  Theresa HillAug 26, 2025
  If your Huawei Network Hardware reports a Grid Overvoltage, there are a few things you can check. If the alarm appears only occasionally, it could be due to a temporary issue with the power grid, and the device should automatically recover when the grid returns to normal. However, if the alarm is frequent, verify that the power grid voltage is within the acceptable range; if it's not, contact your local power operator. If the voltage is within range, you can adjust the grid overvoltage protection threshold using the mobile app or network management system (NMS), but only with the consent of the local power operator. Also, check for high peak voltages on the power grid. If the problem persists, contact your power operator.

What causes Huawei Network Hardware to have String Voltage High?
- D
  dmccarthyAug 27, 2025
  A String Voltage High error on your Huawei Network Hardware usually means that the PV array is not configured correctly. Too many PV modules might be connected in series in the PV string, causing the open-circuit voltage to exceed the device's maximum operating voltage. To fix this, check the serial connection configuration of the PV string to ensure the PV string open-circuit voltage does not exceed the device's maximum operating voltage. Once the PV array configuration is corrected, the alarm should disappear.

How to troubleshoot Huawei Network Hardware AC Overcurrent?
- P
  Paul RussellAug 29, 2025
  If your Huawei Network Hardware is showing an AC Overcurrent error, it indicates a dramatic voltage drop or a short circuit in the grid. The device is designed to detect and rectify external working conditions in real time, so it should automatically recover once the fault is cleared. However, if the alarm occurs frequently and affects the power plant's energy yield, check for a short circuit at the output. If the problem persists, contact your dealer or technical support.

What to do if Huawei Network Hardware shows Grid-tied/Off-grid Controller Abnormal?
- F
  Francisco GonzalesSep 22, 2025
  If your Huawei Network Hardware displays a Grid-tied/Off-grid Controller Abnormal error, it means the device is failing to communicate with the Smart Backup Box. To resolve this: 1. Send a shutdown command on the app. Turn off the AC output switch, DC input switch, and battery switch. 2. Check whether the power cable and RS485 cable between the Smart Backup Box and the device are normal. 3. After 5 minutes, turn on the battery switch, AC output side, AC output switch, and DC input switch.

What to do if Huawei Network Hardware shows Abnormal PV Module Configuration?
- D
  Daryl CooperSep 16, 2025
  If your Huawei Network Hardware reports an Abnormal PV Module Configuration, check whether the total number of PV modules, the number of PV modules in a string, and the number of PV strings meet the required specifications. Also, check if the PV module output is reversely connected.

What does AFCI Check Failure mean for Huawei Network Hardware?
- M
  Mr. Thomas RosalesSep 8, 2025
  If your Huawei Network Hardware reports an AFCI Check Failure, turn off the AC output switch and DC input switch, and then turn them on again after 5 minutes. If the fault persists, contact your dealer or technical support.

What causes Huawei Network Hardware to display Grid Underfrequency?
- G
  griffinbarbaraSep 4, 2025
  If your Huawei Network Hardware shows a Grid Underfrequency error, it means the actual power grid frequency is lower than the standard requirement for the local power grid. If this occurs occasionally, it may be due to a temporary issue with the power grid, and the device should recover automatically. If it occurs frequently, check whether the power grid frequency is within the allowed range and contact the local power operator if it isn't. If the frequency is within range, you can modify the grid underfrequency protection threshold via the mobile app or NMS with the consent of the local power operator.
