Failure Analysis:
When the fan is connected to the controller, the speed of the fan becomes very slow immediately?
1. The battery voltage arrive the floating charging point
2. The rated output voltage of the fan is much higher than the rated voltage of the battery, because the fan speed is proportional to the output voltage, and the fan voltage is dragged by the battery and will not be very high, so the speed will be very low
3. The unloading tube was burnt out in the wrong
Why does the controller unload when the LCD displays a small current value?
The controller controls the unloading by detecting parameters such as battery voltage, charging current and temperature. When the floating charging voltage point is arrived, or when high temperature protection is arrived, no matter how large the charging current is, the fan will unload.
LCD does not display?
1. The battery is in poor , please check the battery connection cable.
2. The battery is damaged, please check and replace the battery.
No charging current?
If the charging voltage is not arrived, the input voltage of the solar panel must be higher than the battery voltage before it can be charged. The fan needs to arrive a certain wind speed in order to generate electricity normally.
