What does grid voltage imbalance mean on a Huawei Inverter?
- A
  Andrea ZavalaAug 30, 2025
  A grid voltage imbalance alarm on your Huawei Inverter means the difference between power grid phase voltages is too high. If the alarm is occasional, it may be a temporary grid issue, and the inverter should recover automatically. If it persists, check if the grid voltage is within the acceptable range and contact the local power operator if it isn't. If the alarm lasts for a long time, check the AC output power cable connection. If the cable is correctly connected, but the alarm persists and impacts energy yield, contact the local power operator.

What to do if Huawei SUN2000-25KTL-M5 Inverter displays phase wire short-circuited to PE?
- P
  pwalkerAug 31, 2025
  If your Huawei Inverter indicates a phase wire short-circuited to PE, it means the impedance of the output phase wire to PE is low, or the output phase wire is short-circuited to PE. Check the impedance of the output phase wire to PE, find the low impedance point, and correct the fault.

What to do if Huawei Inverter shows grid loss?
- M
  Ms. Victoria RobinsonAug 25, 2025
  If your Huawei Inverter displays a grid loss error, it means the power grid is down, the AC circuit is disconnected, or the AC switch is off. The alarm should clear automatically once the power grid recovers. You should also check if the AC circuit is disconnected or the AC switch is turned off.

What does unstable grid frequency mean on my Huawei SUN2000-25KTL-M5 Inverter?
- L
  Laura PerezSep 1, 2025
  An unstable grid frequency alarm on your Huawei Inverter means the rate of change in the power grid frequency doesn't meet local power grid code requirements. If the alarm occurs occasionally, it might be a temporary grid issue and the inverter should recover automatically. If the alarm persists, check whether the power grid frequency is within the acceptable range. If it is not, contact the local power operator.

What to do if Huawei SUN2000-25KTL-M5 Inverter shows device fault?
- D
  Dr. Cynthia BurkeSep 1, 2025
  If your Huawei Inverter displays a device fault, it indicates an unrecoverable fault within the inverter. Turn off the AC output switch and DC input switch, wait 5 minutes, then turn them back on. If the alarm persists, contact your dealer or Huawei technical support. Ensure the PV string current is less than 1 A when performing these steps.

What does abnormal residual current mean on a Huawei SUN2000-25KTL-M5 Inverter?
- J
  Jamie WilliamsSep 2, 2025
  An abnormal residual current on your Huawei Inverter indicates that the insulation impedance on the input side to PE has decreased during operation. If the alarm occurs accidentally, the external power cable may be temporarily abnormal, and the inverter will recover automatically after the fault is rectified. If the alarm persists or lasts a long time, check whether the impedance between the PV string and ground is too low.

Why am I getting an output DC component overhigh error on my Huawei Inverter?
- L
  Lauren SuttonSep 2, 2025
  An output DC component overhigh error on your Huawei Inverter means the DC component of the inverter's output current is too high. The inverter will monitor external conditions and try to recover automatically. If the alarm persists and affects energy yield, contact your dealer or Huawei technical support.

What to do if Huawei Inverter reports abnormal PV module configuration?
- J
  Justin FisherSep 3, 2025
  An abnormal PV module configuration error on your Huawei Inverter means the PV string power or the number of optimizers connected in series in a PV string exceeds the upper threshold. It could also mean the number of optimizers connected in series in a PV string is less than the lower threshold, the PV string output is reversely connected, or the output of some optimizers in the PV string is reversely connected. Check whether the total number of PV modules, number of PV modules in a PV string, and number of PV strings meet requirements and whether the PV module output is reversely connected.

What does built-in PID operation abnormal mean on a Huawei SUN2000-25KTL-M5 Inverter?
- N
  Nathan Martin MDSep 4, 2025
  If your Huawei Inverter displays a built-in PID operation abnormal message, it means the output resistance of PV arrays to ground is low, or the system insulation resistance is low. Turn off the AC output switch and DC input switch, wait for a period of time, and then turn them back on. If the alarm persists, contact your dealer or Huawei technical support.

What to do if Huawei SUN2000-25KTL-M5 reports faulty monitoring unit?
- T
  thomaschristineSep 4, 2025
  A faulty monitoring unit error on your Huawei Inverter means the flash memory is either insufficient or has bad sectors. Turn off the AC output switch and DC input switch, wait 5 minutes, then turn them back on. If the alarm persists, replace the monitoring board or contact your dealer or Huawei technical support.
