How to resolve high string input voltage on a Huawei Inverter?
- B
  Bethany AdkinsAug 26, 2025
  A high string input voltage error on your Huawei Inverter means the PV array isn't properly configured, with too many PV modules connected in series, causing the PV string open-circuit voltage to exceed the inverter's maximum operating voltage. Reduce the number of PV modules connected in series until the PV string open-circuit voltage is at or below the inverter's maximum. The alarm should then disappear.

What causes grid undervoltage on Huawei Inverter?
- L
  Lindsay GonzalezAug 26, 2025
  A grid undervoltage error on your Huawei Inverter means the power grid voltage is too low, or the low voltage duration exceeds the LVRT specified value. Here's how to handle it: 1. If it's occasional, it might be a temporary grid issue; the inverter should recover automatically. 2. If it persists, check if the grid voltage is within range and contact the local power operator if it's not. If it is, you can modify the grid undervoltage protection threshold via the app, SmartLogger, or NMS, with the power operator's consent. 3. If it continues, inspect the AC circuit breaker and AC output power cable.

What to do if Huawei Inverter displays DC arc fault?
- C
  Chad BrownAug 27, 2025
  A DC arc fault on your Huawei Inverter means the PV string power cables are arcing or have poor contact. Check the PV string cables to ensure they are not arcing and are properly connected.

Why is my Huawei SUN2000-12KTL-M5 showing abnormal grounding?
- T
  Tara ThomasAug 27, 2025
  An abnormal grounding error on your Huawei Inverter indicates that the neutral wire or PE cable isn't connected, or the output mode is set incorrectly. To fix this, power off the inverter first (turn off the AC and DC switches and wait). Then: 1. Check the PE cable connection. 2. If connected to a TN grid, check the neutral wire connection and voltage to ground. 3. After powering on, ensure the inverter's output mode matches the cable connection mode.

What to do if Huawei Inverter displays string reverse connection?
- C
  Cynthia OrtizAug 27, 2025
  A string reverse connection error on your Huawei Inverter indicates that the PV string polarity is reversed. Wait until night when solar irradiance is low and the PV string current drops below 0.5 A. Then, turn off the DC switch and correct the PV string connection.

Why is my Huawei SUN2000-12KTL-M5 Inverter cabinet overheating?
- H
  Helen AllenAug 27, 2025
  Cabinet overheating on your Huawei Inverter means it's either installed in a poorly ventilated area, the ambient temperature is too high, or the inverter isn't working correctly. First, check the ventilation and ambient temperature where the inverter is installed. If ventilation is poor or the temperature is too high, improve ventilation and heat dissipation. If both are fine and the alarm persists, contact your dealer or Huawei technical support.

What does grid overfrequency mean on my Huawei SUN2000-12KTL-M5?
- H
  harristimothyAug 28, 2025
  A grid overfrequency alarm on your Huawei Inverter means the power grid frequency is too high, exceeding local power grid code requirements. 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 frequency is within the acceptable range and contact the local power operator if it isn't. If the frequency is normal, you can modify the grid overfrequency protection threshold using the app, SmartLogger, or NMS, with the local power operator's consent.

What to do if Huawei SUN2000-12KTL-M5 Inverter shows AFCI self-check failure?
- T
  Tammy ScottAug 29, 2025
  If your Huawei Inverter shows an AFCI self-check failure, turn off both the AC output switch and the DC input switch. Wait for 5 minutes, then turn them back on. If the alarm continues, contact Huawei technical support.

What does it mean when my Huawei Inverter displays grid underfrequency?
- A
  Amy BeltranAug 29, 2025
  A grid underfrequency alarm on your Huawei Inverter indicates that the power grid frequency is lower than the local power grid code requirements. If the alarm occurs occasionally, it might be due to a temporary grid issue, and the inverter should recover automatically. If the alarm persists, verify that the power grid frequency is within the acceptable range. If it is not, contact the local power operator. If the frequency is within range, you can modify the grid underfrequency protection threshold through the app, SmartLogger, or NMS with the consent of the local power operator.

Why is my Huawei SUN2000-12KTL-M5 showing an output overcurrent error?
- M
  mhobbsAug 30, 2025
  An output overcurrent error on your Huawei Inverter indicates that the grid voltage has dropped dramatically or the grid is short-circuited, causing the inverter's output current to exceed the limit. The inverter will monitor conditions and try to recover automatically. If the alarm persists and affects energy yield, check for a short circuit in the output. If you can't fix it, contact your dealer or Huawei technical support.
