How Outdoor Solar Lanterns Work

The principle of automatic lighting of Outdoor Solar Lanterns: The automatic lighting of Outdoor Solar Lanterns after dark is realized by a solar controller.

The solar panels will generate electricity during the day and be stored in the battery through the controller. When there is no sun at night, the solar panels will not generate electricity, and the controller will not sense the current, thinking that it is dark, and will discharge and turn on the lights.

Reasons why Outdoor Solar Lanterns do not light up automatically:

1. The solar panel is broken and does not generate electricity, and the controller cannot sense current.

2. The positive and negative poles of the solar panel are connected reversely, and the power emitted cannot be charged into the controller, so the lights will not light up.

3. The solar panel junction box is not welded properly, and may be weakly welded, causing the power generated not to be sent out, and the charging module inside the controller to be broken down, causing the controller to be unable to charge.

4. In rainy weather, the solar panels absorb insufficient solar radiation and emit weak power, and the controller will think it is dark. The time in the controller of Outdoor Solar Lanterns are messed up. If the lights are on for more than 12 hours a day, the lights will also be on during the day.
