The most basic function of the solar charge and discharge controller is to control the battery voltage and turn on the circuit, and when the battery voltage rises to a certain level, stop the battery charging. The older version of the controller mechanically completed the opening or closing of the control circuit, stopping or starting the power delivered to the battery. The solar regulator company will explain to you the relevant precautions of solar regulators.

1. Open the package and fix it in a suitable position (please avoid direct sunlight and damp places).
2. Connect the battery leads first (in order to prevent errors in the automatic identification function), and wait for the controller to complete the identification process (after the level indicator shows the battery power), then connect the solar panel leads, and finally connect the solar panel leads when the load is turned off. Connect the load line in case.
3. In order to use it safely, do not make too much load or increase the solar panel too large; use a power supply such as a power supply to replace the solar battery to charge the battery.
4. When charging, remove the solar panel, and the charging current should not be too large.
4. Pay attention to the positive and negative poles of the battery.
