What to do if the inverter is abnormal in Huawei UPS?
If the inverter in your Huawei UPS is abnormal, it could be due to an overload or a short circuit. Try reducing the load or rectifying any short circuits. Insufficient ventilation can also cause problems, so install more air conditioners or ventilation devices to ensure normal temperatures inside the equipment room. If these steps don't resolve the issue, the power module may need to be replaced.
What to do if the inverter is not normal in Huawei Control Unit?
If the inverter in your Huawei Control Unit is not normal, it could be due to an output overload or a short-circuit. In this case, reduce the load or troubleshoot the short circuit. Alternatively, the power module itself might be faulty, requiring replacement.
What to do if the rectifier is not normal in Huawei Control Unit?
If the rectifier in your Huawei Control Unit is not normal, it could be due to several reasons. The mains voltage might be exceeding the upper threshold of 280 V or falling below the lower threshold of 80 V. In this case, check whether the mains voltage is within the allowed range and contact the electric power company if it is not. Another potential cause is a failure of the PFC soft-startup or a faulty power module. In either of these situations, the suggested solution is to replace the power module.
What to do if the Huawei Control Unit charger generates an alarm?
If the Huawei Control Unit charger generates an alarm, it could be due to several reasons. One possibility is that the charger itself has failed or is experiencing overcurrent. In these cases, the suggested solution is to replace the power module. Another cause might be undervoltage. To resolve this, first verify that the configured number of batteries is correct. If the setting is correct and the alarm persists, then replace the power module.
How to fix a Huawei Power Supply UPS that works in bypass mode and does not transfer to inverter mode?
If the UPS is stuck in bypass mode and isn't transferring to inverter mode, try setting the UPS working mode to ECO mode. Additionally, clear the bypass transfer times on the LCD.
What to do if the bypass is not normal in Huawei Power Supply?
If the bypass is not normal, the bypass thyristor may be damaged, requiring replacement of the bypass module. Also, try reducing the load or improving ventilation.
What to do if the rectifier is not normal in Huawei Power Supply?
If the rectifier is not normal, it may be because the mains voltage exceeds the upper threshold of 280 V or is less than the lower threshold of 80 V. Check whether the mains voltage exceeds these thresholds, and if it does, contact the electric power company. If the voltage is within range, consider replacing the power module.
What to do if the inverter is not normal in Huawei Power Supply?
If the inverter is not normal, it could be due to the UPS being overloaded or short-circuited. Try reducing the load or rectifying any short circuits. Ensure normal temperatures inside the equipment room by installing more air conditioners or ventilation devices. Alternatively, the power module may need replacement.
Why does my Huawei Control Unit UPS work in bypass mode?
If your Huawei Control Unit UPS works in bypass mode and does not transfer to inverter mode, it might be because the UPS is set to ECO mode. To resolve this, set the working mode correctly. Another reason could be that the number of bypass transfer times has reached the upper limit. In this case, choose 'Clear Faults' on the LCD.
Why is the bypass abnormal in my Huawei Control Unit?
If the bypass of your Huawei Control Unit is abnormal, it could be due to a damaged bypass thyristor, in which case you should replace the bypass module. Alternatively, the bypass module might be experiencing overtemperature. To resolve this, try reducing the load or improving ventilation.
