How to debug the 15W solar street light controller?

Press the key for more than 3 seconds and the nixie tube will start flashing. The system will enter the adjustment mode and release the key. Each time you press the key, the nixie tube number will change to a number until the number displayed by the nixie tube matches the number corresponding to the mode selected by the user from the table. The setting will be completed when the nixie tube stops flashing or press the key for more than 3S again.

Battery status indication: when the battery voltage is in the normal range, the status indicator light (2) is green and normally on; when the battery voltage is reduced to under voltage, the status indicator light turns orange;

When the battery voltage continues to decrease to the over-discharge voltage, the status indicator (2) turns red, and the controller will automatically turn off the output to remind the user to supplement the power in time. When the battery voltage returns to the normal working range, it will automatically enable the output of the opening act, and the status indicator (2) will turn green.

1： The controller with low power consumption should be selected. The controller will work continuously for 24 hours. If the power consumption is large, part of the power will be consumed. The controller with power consumption less than 1 Ma is the best choice.

2： To choose a controller with high charging efficiency, the controller with MCT charging mode can automatically track the maximum current of the battery board, especially in winter or in the period of insufficient light, MCT charging mode is about 20% higher than other charging modes.

3： The controller with two-way power regulation should be selected. The controller with power regulation has been widely promoted. One or two-way lighting can be automatically turned off when pedestrians are scarce at night to save power, and power regulation can also be carried out for LED 15W solar street lights.

In addition to the above energy-saving functions, the controller should also pay attention to the protection function of the battery and other components. For example, the controller with a trickle charging mode can protect the battery well and increase the battery life. Besides, when setting the Undervoltage protection value of the controller, try to adjust the Undervoltage protection value to ≥ 11.1v to prevent the battery from being over-discharged.
