Why is my Huawei SUN2000-15KTL-M5 Inverter showing an output overcurrent error?
- JJessica MontgomeryAug 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.
