How to fix Faulty Power Collector on Huawei Inverter?
- M
  Michele VegaAug 31, 2025
  If your Huawei Inverter displays 'Faulty Power Collector', it means the smart power sensor is disconnected. To resolve this: 1. Check that the configured power meter model matches the actual model. 2. Verify that the communication parameters for the smart power sensors are the same as the SUN2000 RS485 configurations. 3. Ensure the smart power sensor is powered on and the RS485 communication cable is connected.

Why is Huawei Inverter showing Output Overcurrent?
- K
  Kim FuentesSep 1, 2025
  If your Huawei Inverter is showing an 'Output Overcurrent' error, it means the grid voltage dropped dramatically or the grid is short-circuited, causing the SUN2000's transient output current to exceed the 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 and affects the energy yield of the power plant, check whether the output is short-circuited. If the fault persists, contact your dealer or Huawei technical support.

- D
  Daniel JohnstonSep 2, 2025
  If your Huawei Inverter is showing 'Active Islanding', it means the SUN2000 proactively detected islanding when the power grid experienced an AC power outage. Check that the grid connection voltage of the SUN2000 is normal.

Why is Huawei Inverter showing Off-grid output overload?
- E
  Emily PierceSep 3, 2025
  If your Huawei Inverter shows an 'Off-grid output overload' message, the output is either overloaded or short-circuited. Check whether the device output is short-circuited and whether the device load configuration exceeds the rated value.

What does Output DC Component Overhigh mean on Huawei Inverter?
- K
  Katie FletcherSep 3, 2025
  If your Huawei Inverter displays 'Output DC Component Overhigh', it signifies that the DC component of the SUN2000 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.
