What to do if my Huawei SUN2000-(2KTL-6KTL)-L1 displays 'AFCI Check Failure'?
If your Huawei Inverter is showing an AFCI Check Failure, turn off the AC output switch and DC input switch, and then turn them back on after 5 minutes. If the fault persists, contact your dealer or Huawei technical support.
How to resolve an Overtemperature warning on a Huawei SUN2000-(2KTL-6KTL)-L1?
If your Huawei Inverter is overheating, improve the ventilation and heat dissipation around the installation area, especially if the ambient temperature is high.
What does 'Abnormal PV Module' mean on my Huawei SUN2000-(2KTL-6KTL)-L1?
If your Huawei Inverter reports an abnormal PV module, it could be due to several reasons: the PV module doesn't meet requirements, or the PV module output is reversely connected or short-circuited. Check whether the total number of PV modules, the number of modules in a string, and the number of PV strings meet the specified requirements. Also, verify that the PV module output is not reversely connected.
What does it mean if my Huawei SUN2000-(2KTL-6KTL)-L1 Inverter shows 'Output DC Component Overhigh'?
If your Huawei Inverter displays an 'Output DC Component Overhigh' error, it means the DC component of the output current exceeds the upper threshold. The inverter detects its external working conditions in real time and should automatically recover after the fault is cleared. If the alarm occurs frequently, contact your dealer or Huawei technical support.
What should I do if my Huawei SUN2000-(2KTL-6KTL)-L1 reports a Device Fault?
If your Huawei Inverter is showing a device fault, turn off the AC output switch and DC input switch, and then turn them on again after 5 minutes. If the fault persists, contact your dealer or Huawei technical support, as this indicates an unrecoverable internal fault.
What to do if my Huawei Inverter Upgrade Failed or shows Version Mismatch?
If the upgrade process for your Huawei Inverter fails or you encounter a version mismatch, try performing the upgrade again. If it fails multiple times, contact your dealer or Huawei technical support for assistance.
