Why is my Huawei SUN2000-8KTL-M0 Inverter showing Grid Overfrequency and how do I fix it?
- C
  cooperhannahSep 1, 2025
  If your Huawei Inverter displays a 'Grid Overfrequency' alarm, it means the power grid frequency is higher than the standard requirement for your local power grid. To address this: 1. If the alarm occurs occasionally, it may be due to a temporary power grid abnormality. The SUN2000 will automatically recover when the grid returns to normal. 2. If the alarm occurs frequently, check whether the grid frequency is within the acceptable range. If not, contact your local power operator. If it is, log in to the mobile phone app, SmartLogger, or NMS to modify the grid overfrequency protection threshold.

What to do if Huawei SUN2000-8KTL-M0 shows Grid Loss?
- S
  Shawn SimonAug 25, 2025
  If your Huawei Inverter indicates a 'Grid Loss' error, it means the power grid might be experiencing an outage, or the AC power cable could be disconnected, or the AC circuit breaker is OFF. To resolve this, first, verify that the AC voltage is normal. Second, ensure that the AC power cable is properly connected and the AC switch is in the ON position.

How to fix Low Insulation Resistance on Huawei SUN2000-8KTL-M0?
- A
  ashleyrubioAug 26, 2025
  If your Huawei Inverter displays a 'Low Insulation Resistance' error, it could be due to the PV array being short-circuited to ground or the power cable not being well insulated, especially in a moist environment. Here's what you should do: * Check the impedance between the PV array output and PE, and eliminate any short circuits or points of poor insulation. * Ensure the PE cable for the inverter is correctly connected. * If you're certain the impedance is less than the preset protection threshold in cloudy or rainy conditions, you can log in to the mobile app, SmartLogger, or NMS to reset the insulation impedance protection threshold.

What to do if my Huawei SUN2000-8KTL-M0 shows a Grid Failure?
- N
  nlambAug 26, 2025
  If your Huawei Inverter reports a grid failure, it means that the power grid has experienced an outage, the AC circuit is disconnected, or the AC switch is off. To resolve this, first, check the AC voltage. Second, check whether the AC circuit is disconnected or the AC switch is off.

How to fix String Reversed error on Huawei Inverter?
- D
  Derrick MullenAug 27, 2025
  If your Huawei Inverter displays a 'String Reversed' error, it means the PV string is reversely connected. To fix this, wait until night when solar irradiance declines and the PV string current drops below 0.5 A. Then, set the DC SWITCH to the OFF position and correct the string polarity.

What causes Low Insulation Resistance in Huawei Inverter and how to fix it?
- J
  Jason BowmanAug 27, 2025
  If your Huawei Inverter is showing a 'Low Insulation Resistance' error, it means that the PV arrays are short-circuited with PE, or the ambient air of the PV array is damp, leading to poor insulation between the PV array and the ground. Here's how to address it: 1. Check the output resistance of the PV array to ground. Rectify any short circuits or insulation issues. 2. Ensure the PE cable of the SUN2000 is correctly connected. 3. If the low impedance persists in cloudy or rainy conditions, log in to the mobile app, SmartLogger, or NMS to reset the insulation impedance protection threshold.

What does Output DC Component Overhigh mean on my Huawei Inverter and how to resolve it?
- K
  Kevin SnyderSep 5, 2025
  If your Huawei Inverter displays an 'Output DC Component Overhigh' error, it indicates that the DC component of the 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. If the alarm occurs frequently, contact your dealer or Huawei technical support.

What causes Transient AC Overvoltage on a Huawei SUN2000-8KTL-M0 and how can I fix it?
- M
  Megan DavisSep 5, 2025
  If your Huawei Inverter reports a 'Transient AC Overvoltage' error, it means the inverter has detected that the phase voltage exceeds the transient AC overvoltage protection threshold. 1. Check if the grid connection voltage exceeds the upper threshold. If yes, contact the local power operator. 2. If you have confirmed that the grid-tied voltage exceeds the upper threshold and have obtained the consent of the local power operator, modify the overvoltage protection threshold through the mobile phone app, SmartLogger, or NMS. 3. Check whether the peak power grid voltage exceeds the upper threshold.

What does Unbalanced Grid Voltage mean on my Huawei SUN2000-8KTL-M0?
- S
  Seth ParrishSep 1, 2025
  If your Huawei Inverter is showing an 'Unbalanced Grid Voltage' error, it means that the difference between grid phase voltages exceeds the upper threshold. Here's what to do: 1. If the alarm occurs occasionally, the power grid may be temporarily abnormal. The SUN2000 automatically recovers after detecting that the power grid becomes normal. 2. If the alarm occurs frequently, check whether the grid voltage is within the acceptable range. If no, contact the local power operator. 3. If the fault persists for a long time, check the connection between the AC switch and the output power cable.

What causes String Current Backfeed on a Huawei SUN2000-8KTL-M0 and how to resolve it?
- V
  Victoria HallAug 29, 2025
  If your Huawei Inverter reports 'String Current Backfeed,' it means that too few PV modules are connected in series, causing the end voltage to be lower than other PV strings. To resolve this: 1. Check if the number of PV modules connected in series is less than that of other PV strings. If so, wait until the PV string current drops below 0.5 A, set the DC SWITCH to OFF, and adjust the number of PV modules. 2. Check if the PV string is shaded. 3. Check if the open-circuit voltage of the PV string is normal.
