What to do if Huawei SUN2000-12KTL-M5 Inverter upgrade failed?
If your Huawei Inverter displays an upgrade failed or version mismatch error, it means the upgrade process wasn't completed correctly. Try performing the upgrade again. If it fails multiple times, contact your dealer or Huawei technical support.
Why is my Huawei SUN2000-12KTL-M5 showing an external fan abnormal error?
An external fan abnormal error on your Huawei Inverter indicates that the external fan is short-circuited, the power supply is insufficient, or the air channel is blocked. Shut down the fan, turn off the DC switch, check for damage to the fan blades, and clear any obstructions around the fan. 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.
What should I do if my Huawei Inverter reports a faulty power collector?
A faulty power collector error on your Huawei Inverter indicates that the power meter is disconnected. Check the following: 1. Ensure the configured power meter model matches the actual model. 2. Verify that the power meter's communication parameters match the inverter's RS485 configurations. 3. Confirm that the power meter is powered on and the RS485 communication cable is connected.
What does abnormal active power scheduling instruction mean on a Huawei Inverter?
If your Huawei Inverter displays an abnormal active power scheduling instruction, it means the DI input is abnormal or inconsistent with the configuration. Check whether the cables are correctly connected to the DI ports. On the DI active scheduling screen under the dry contact scheduling settings, view the DI signal configuration mapping table. Contact the power grid company to check whether the configurations in the mapping table are complete and meet the requirements.
What does abnormal reactive power scheduling instruction mean on a Huawei SUN2000-12KTL-M5?
If your Huawei Inverter displays an abnormal reactive power scheduling instruction, it means the DI input is abnormal or inconsistent with the configuration. Check whether the cables are connected correctly to the DI ports. On the DI reactive power scheduling screen under the dry contact scheduling settings, view the DI signal configuration mapping table. Contact the power grid company to check whether the configurations in the mapping table are complete and meet the requirements.
