  Jeffery GrossAug 22, 2025
  If the LCD is blinking and the buzzer beeps twice every second, it indicates that the UPS is overloaded. Here's what you should do: * Remove surplus load from the UPS output end. In some instances, the UPS might be overloaded multiple times in quick succession, causing it to lock in bypass mode. If this happens, remove the extra load, then shut down and restart the UPS.

  If your Huawei UPS buzzer beeps twice every second, it means the UPS is overloaded. You should remove some of the load from the UPS output. In some cases, the UPS might be overloaded repeatedly, causing it to lock in bypass mode. If this happens, remove the extra load, then shut down and restart the UPS.

Why is the Huawei UPS2000-G battery backup time shorter than specified?
- K
  kevincastilloAug 29, 2025
  If the battery backup time of your Huawei UPS is shorter than expected, it could be due to a couple of reasons. First, the batteries may not be fully charged. Try charging them for at least 5 hours before checking their capacity again. If the battery capacity is still not enough, or if you suspect the batteries are faulty, you should contact the dealer to replace the batteries.

How to troubleshoot a Huawei UPS2000-G with no indicator lights and no buzzer tone?
- J
  Joyce MillerAug 31, 2025
  If no indicator lights up and the buzzer makes no sound on your Huawei UPS, it could be due to a disconnected mains input power cable. Ensure the input power cable is properly connected. Also, verify that the mains input power cable is correctly connected to the UPS input terminal, and not incorrectly connected to the UPS output end.

Why is my Huawei UPS battery discharge time so short?
- M
  Mark MartinSep 4, 2025
  The battery discharge time may be shorter than expected because the batteries are not fully charged. To resolve this, charge the batteries for at least 8 hours when the mains is normal, and then test the discharge time again. Alternatively, the battery performance might have deteriorated, in which case you should contact local technical support to replace the batteries.

What to do if the AC input indicator is off on my Huawei UPS2000-G UPS?
- J
  John TaylorSep 5, 2025
  If the AC input indicator is off and the UPS is running on battery despite normal mains, it could be due to the UPS mains switch being OFF. Ensure the UPS mains switch is turned ON. Alternatively, the input cable may not be properly connected; check the UPS input power cable connection.
