Why am I getting an output DC component overhigh error on my Huawei Inverter?
An output DC component overhigh error on your Huawei Inverter means the DC component of the inverter's output current is too high. The inverter will monitor external conditions and try to recover automatically. If the alarm persists and affects energy yield, contact your dealer or Huawei technical support.
What to do if Huawei SUN2000 Inverter reports abnormal PV module configuration?
An abnormal PV module configuration error on your Huawei Inverter means the PV string power or the number of optimizers connected in series in a PV string exceeds the upper threshold. It could also mean the number of optimizers connected in series in a PV string is less than the lower threshold, the PV string output is reversely connected, or the output of some optimizers in the PV string is reversely connected. Check whether the total number of PV modules, number of PV modules in a PV string, and number of PV strings meet requirements and whether the PV module output is reversely connected.
How to troubleshoot Abnormal PV Module Configuration on Huawei SUN2000 Inverter?
If your Huawei Inverter reports 'Abnormal PV Module Configuration,' it means the PV module configuration 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 PV modules in a string, and the number of PV strings meet requirements, and verify that the PV module output isn't reversely connected.
Why is my Huawei SUN2000 Inverter showing Grid Overfrequency?
If the Huawei Inverter displays a 'Grid Overfrequency' alarm, it means the power grid frequency is higher than the standard requirement. If the alarm occurs occasionally, the power grid may be temporarily abnormal, and the SUN2000 will recover automatically. If the alarm occurs frequently, check if the grid frequency is within the acceptable range. If not, contact the local power operator. If it is, log in to the mobile phone app, SmartLogger, or NMS to modify the grid overfrequency protection threshold.
What to do if my Huawei SUN2000 shows 'Cabinet overtemperature'?
If your Huawei Inverter displays a 'Cabinet overtemperature' alarm, it could be due to: ? The inverter being installed in a place with poor ventilation. ? The ambient temperature exceeding the upper threshold. ? The inverter not operating properly. Check the ventilation and ambient temperature at the inverter installation position. If the ventilation is poor or the ambient temperature exceeds the upper threshold, improve the ventilation and heat dissipation. If both the ventilation and ambient temperature meet requirements yet the alarm persists, contact your dealer or Huawei technical support.
What should I do if my Huawei SUN2000 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 SUN2000 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 Inverter?
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.
What to do if my Huawei SUN2000 Inverter shows Grid Loss?
If your Huawei Inverter indicates a Grid Loss, it means there might be an outage in the power grid, the AC power cable could be disconnected, or the AC circuit breaker might be off. To resolve this, first, verify that the AC voltage is normal. Second, ensure that the AC power cable is properly connected and the AC switch is turned ON.
How to fix Upgrade Failed on Huawei Inverter?
If your Huawei Inverter displays 'Upgrade Failed or Version Mismatch,' it means the upgrade ended abnormally. To resolve this, try upgrading again. If the upgrade fails multiple times, contact your dealer or Huawei technical support.
