What causes DC arc on Huawei SUN2000-50KTL-ZHM3?
If you see a DC arc on your Huawei Inverter, it means that the PV string power cables are arcing. Check whether the PV string cables arc or are in poor contact.
What to do if I see a DC arc fault on my Huawei SUN2000-50KTL-ZHM3?
If you are seeing a DC arc fault on your Huawei Inverter, the PV string power cables may be arcing or have poor contact. Check the PV string cables to see if they are arcing or are in poor contact.
How do I fix an external fan abnormal error on my Huawei Network Hardware?
1. Shut down the fan, turn off the DC switch, check whether the fan blades are damaged, and clear the foreign matter around the fan. 2. Reinstall the fan, turn on the DC switch, and wait for the inverter to start. If the alarm persists after 15 minutes, replace the external fan.
How to fix phase wire short-circuited to PE on Huawei SUN2000-50KTL-ZHM3 Inverter?
A 'Phase wire short-circuited to PE' error on your Huawei Inverter means the impedance of the output phase wire to PE is low, or the output phase wire is short-circuited to PE. You should check the impedance of the output phase wire to PE, find the low impedance location, and correct the fault.
What to do if my Huawei Network Hardware shows a grid overfrequency alarm?
If the alarm occurs occasionally, the power grid may be abnormal temporarily and 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.
What to do for grid undervoltage on Huawei SUN2000-50KTL-ZHM3?
A 'Grid undervoltage' alarm on your Huawei Inverter indicates that the power grid voltage is too low. If it happens occasionally, it might be a temporary issue, and the inverter should recover automatically. If the alarm persists, verify that the power grid voltage is within the acceptable range with your local power operator. If it is within range, you can modify the grid undervoltage protection threshold using the app, SmartLogger, or NMS, with the consent of the local power operator. If the alarm continues, inspect the AC circuit breaker and AC output power cable.
What causes a cabinet overtemperature error on a Huawei SUN2000-50KTL-ZHM3 Inverter?
A cabinet overtemperature error on a Huawei Inverter is caused by the inverter being installed in a poorly ventilated area. Check the ventilation and ambient temperature at the installation location. If ventilation is poor or the temperature is too high, improve ventilation and heat dissipation.
How do I resolve an AFCI self-check failure on my Huawei Network Hardware?
Turn off the AC output switch and DC input switch, and then turn them on after 5 minutes. If the alarm persists, contact Huawei technical support.
What does built-in PID operation abnormal mean on Huawei SUN2000-50KTL-ZHM3?
A 'Built-in PID operation abnormal' alarm on your Huawei Inverter suggests a low output resistance of PV arrays to ground or low system insulation resistance. First, turn off the AC and DC switches, wait, and then turn them back on. If the alarm persists, contact your dealer or Huawei technical support. Also, check the impedance between the PV array output and the ground for short circuits or insufficient insulation, and rectify any faults.
What causes an output overcurrent on my Huawei SUN2000-50KTL-ZHM3?
An output overcurrent on your Huawei Inverter is triggered when the power grid voltage drops dramatically or the power grid is short-circuited, causing the inverter's transient output current to exceed the upper threshold. The inverter will automatically recover once the fault is rectified. If the alarm persists and affects the energy yield, check whether the output is short-circuited.
