How to troubleshoot 'Built-in PID operation abnormal' on Huawei SUN2000-30KTL-M3 Inverter?
- C
  Cameron MartinezSep 23, 2025
  If you encounter a 'Built-in PID operation abnormal' error on your Huawei Inverter: ? If Cause ID = 1: Turn off the AC output switch and DC input switch, wait for a period of time, and then turn on the DC input switch and AC output switch. If the alarm persists, contact your dealer or Huawei technical support. ? If Cause ID = 2: Check the impedance between the PV array output and the ground. If a short circuit occurs or the insulation is insufficient, rectify the fault. If the alarm persists, contact your dealer or Huawei technical support.

Why is my Huawei SUN2000-30KTL-M3 Inverter showing 'High string input voltage'?
- N
  Nicholas BlakeAug 25, 2025
  The 'High string input voltage' error on your Huawei Inverter means the PV array isn't configured correctly. There are too many PV modules connected in series, causing the PV string open-circuit voltage to exceed the inverter's maximum operating voltage. To fix this, reduce the number of PV modules connected in series until the PV string open-circuit voltage is at or below the maximum inverter operating voltage. The alarm should then disappear.

What to do if my Huawei SUN2000-30KTL-M3 Inverter displays 'DC arc fault'?
- J
  John CareyAug 26, 2025
  If your Huawei Inverter is showing a 'DC arc fault', it means the PV string power cables are arcing or have poor contact. You should check the PV string cables for arcing or poor connections.

What causes 'String reverse connection' in Huawei SUN2000-30KTL-M3 and how to fix it?
- P
  Pamela SalasAug 27, 2025
  The 'String reverse connection' error in your Huawei Inverter means the PV string polarity is reversed. To resolve this, wait until night when solar irradiance decreases and the PV string current drops below 0.5 A. Then, turn off both DC switches and correct the PV string connection.

Why does my Huawei Inverter show 'Grid overvoltage'?
- P
  parkjesseAug 27, 2025
  A 'Grid overvoltage' alarm on your Huawei Inverter indicates that the power grid voltage exceeds the upper threshold, or the high voltage duration has exceeded the value specified by HVRT. If the alarm is occasional, the power grid may be temporarily abnormal, and the inverter should recover automatically. If the alarm persists, check if the power grid frequency is within the acceptable range, and contact the local power operator if it is not. If the frequency is normal, consider modifying the grid overfrequency protection threshold through the app, SmartLogger, or NMS with the consent of the local power operator. Also, check whether the peak voltage of the power grid is too high, and if the alarm persists long-term, contact the local power operator.

What does it mean if my Huawei SUN2000-30KTL-M3 Inverter shows a 'Device fault'?
- C
  Christina ParkerSep 15, 2025
  If your Huawei Inverter displays a 'Device fault', it indicates an unrecoverable fault has occurred within the inverter's internal circuitry. To attempt a resolution, turn off the AC output switch and DC input switch, wait 5 minutes, and then turn them back on. If the alarm persists, contact your dealer or Huawei technical support.

What does 'Abnormal residual current' mean on Huawei Inverter?
- K
  karenpetersSep 12, 2025
  An 'Abnormal residual current' alarm on your Huawei Inverter indicates that the insulation impedance of the input side to PE decreases when the inverter is operating. If the alarm occurs accidentally, the external power cable may be abnormal temporarily, and the inverter automatically recovers 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.

What to do if Huawei SUN2000-30KTL-M3 Inverter displays 'AFCI self-check failure'?
- B
  browncharlesSep 14, 2025
  To address an 'AFCI self-check failure' on your Huawei Inverter, turn off the AC output switch and DC input switch, and then turn them on again after 5 minutes. If the alarm persists, contact Huawei technical support.

How to deal with 'Low insulation resistance' error on Huawei SUN2000-30KTL-M3 Inverter?
- B
  boydelizabethSep 5, 2025
  If your Huawei Inverter is showing a 'Low insulation resistance' error, it could be due to: ? The PV array being short-circuited with PE. ? The PV string being in a moist environment for a long time, and the circuit not being well insulated to ground. To address this: ? Check the impedance between the PV string and the PE cable. If a short circuit occurs, rectify the fault. ? Check whether the PE cable of the inverter is correctly connected. ? If you've confirmed that the impedance is lower than the specified protection threshold in a cloudy or rainy environment, log in to the app, SmartLogger, or NMS and set the Insulation resistance protection threshold.

What does 'Grid underfrequency' mean for Huawei Inverter?
- E
  eric08Sep 2, 2025
  A 'Grid underfrequency' alarm on your Huawei Inverter indicates a power grid exception. The actual power grid frequency is lower than the requirements for the local power grid code. If the alarm occurs occasionally, the power grid may be temporarily abnormal. The inverter automatically recovers after detecting that the power grid becomes normal. If the alarm persists, check whether the power grid frequency is within the acceptable range. If not, contact the local power operator. If yes, modify the grid underfrequency protection threshold through the app, SmartLogger, or NMS with the consent of the local power operator.
