Why is my Huawei SUN2000-8KTL-M0 Inverter showing Output DC Component Overhigh?
If your Huawei Inverter is showing an 'Output DC Component Overhigh' error, it means the DC component in the grid current exceeds the upper threshold. The inverter monitors its external working conditions in real time and will automatically recover after the fault is rectified. If the alarm occurs frequently, contact your dealer or Huawei technical support.
What does Grid Overvoltage mean on my Huawei SUN2000-8KTL-M0 and how can I fix it?
If your Huawei SUN2000 Inverter is showing a 'Grid Overvoltage' error, it means the power grid voltage is beyond the upper threshold or the overvoltage duration exceeds the value specified by HVRT. Here's what you can 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 not, contact the local power operator. If yes, log in to the mobile phone app, SmartLogger, or NMS to modify the grid overvoltage protection threshold with the consent of the local power operator. 3. Check whether the peak voltage of the power grid is too high. If the fault persists and cannot be rectifi...
What does Unbalanced Grid Voltage mean on my Huawei SUN2000-8KTL-M0?
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 to do if Huawei SUN2000-8KTL-M0 shows Grid Loss?
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?
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?
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?
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?
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.
How to troubleshoot High String Input Voltage on Huawei SUN2000-8KTL-M0 Inverter?
A 'High String Input Voltage' error on your Huawei SUN2000 Inverter indicates that too many PV modules are connected in series, causing the open-circuit voltage to exceed the inverter's maximum input voltage. To solve this, check the number of PV modules connected in series and ensure the PV string open-circuit voltage is within the inverter's maximum operating voltage. After correcting the PV array configuration, the alarm should disappear automatically.
What causes DC Arc Fault in Huawei SUN2000-8KTL-M0 Inverter?
A 'DC Arc Fault' error on your Huawei Inverter means the PV string power cable is arcing or has a poor connection. Check whether the string cables arc or are in poor contact.
