If the energy storage power supply display shows abnormal symbols and cannot be used, it may be caused by internal failure of the power supply, external environment, or improper use. If your power supply has the following problems, please follow the methods in this article to troubleshoot and solve the abnormal problems.
| Phenomenon | Troubleshooting | Solution | Remark |
| 1. Display the low battery symbol |
1. If it can be charged normally, it is caused by a low battery. You can charge it and continue using it. 2. If it cannot be charged, contact after-sales service. |
Charging check/contact after-sales service | / |
| 2. Display overcharge symbol |
Check the energy storage power supply display and reset it. If the abnormal symbol cannot be cleared, it is an internal fault. | Reset. If there is no improvement, please contact after-sales service. | / |
| 3. Display high-temperature symbol |
Check the ambient temperature of the power supply. If the temperature is too high, the high-temperature protection will be triggered; when the temperature becomes normal, the symbol will disappear. If there is no problem with the ambient temperature, it is an internal fault. | If it is an internal failure, please contact after-sales service. |
1. Confirm whether the ambient temperature meets the standards 2. The over-temperature symbol (high temperature) is displayed, indicating that the power supply has entered the temperature protection state. At this time, charging and discharging are not possible, and the cause of the failure needs to be found. |
| 4. Display low temperature symbol |
Check the ambient temperature of the power supply. Low temperature will trigger low temperature protection; the symbol will disappear when the temperature becomes normal. If there is no problem with the ambient temperature, it is an internal fault. | If it is an internal failure, please contact after-sales service. |
1. Confirm whether the ambient temperature meets the standards 2. The over-temperature symbol (high temperature) is displayed, indicating that the power supply has entered the temperature protection state. At this time, charging and discharging are not possible, and the cause of the failure needs to be found. |
| 5. Display overload symbol |
Check device power. The power of the device exceeds the rated power of the power supply, resulting in overload protection and an overload symbol will appear. Simply disengage (unplug) the device and reboot (using a device within rated power) to recover. After removing the load, if it cannot be used, it is an internal fault and requires repair. | If it is an internal failure, please contact after-sales service. | It needs to be checked according to the rated power of the equipment and the rated power of the power supply. |
