What to do if the Huawei Control Unit inverter is not normal?
If your Huawei Control Unit inverter isn't working normally, it might be due to an overload or a short circuit. Try reducing the load or fixing any short circuits. Alternatively, the power module could be faulty, in which case you should replace it.
Why does my Huawei Control Unit UPS work in bypass mode and not transfer to inverter mode?
If the Huawei Control Unit UPS is stuck in bypass mode and won't switch to inverter mode, the working mode might be incorrectly set; ensure it's set correctly. Also, if the bypass transfer times have reached their limit, clear the faults on the LCD.
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. The charger itself might be failing, or it could be experiencing overcurrent or undervoltage. In the case of charger failure or overcurrent, replace the power module. If it's undervoltage, check if the configured number of batteries is correct. If it is correct and the alarm persists, replace the power module.
What to do if the Huawei Control Unit bypass is not normal?
If the Huawei Control Unit bypass is not working normally, it could be due to a damaged bypass thyristor, which requires replacing the bypass module. Another reason could be the bypass module experiencing overtemperature. In this case, reduce the load or improve ventilation.
Why is the Huawei Control Unit rectifier not working, and the bus voltage is not boosted?
If the rectifier of your Huawei Control Unit isn't working and the bus voltage isn't being boosted, it might be because the mains voltage is too high (above 280 V) or too low (below 80 V). Check the mains voltage against these thresholds, and if it's outside this range, contact the electric power company.
