This MPPT solar controller has light control and time control. You can manage the DC output of the solar controller in these two ways.
Light control refers to when the night comes, the DC output is automatically turned on. The main principle is that the controller will detect the voltage of the solar panel and automatically turn on the DC output when the voltage is below a certain value.
Time control refers to time control. The DC output is controlled by setting the time. This time is consistent with the local time. Because there is a clock in the MPPT controller, this function is liked by many customers. http://www.didisolar.com
