MPPT 40A Solar Charge and Discharge Controller 12V 24V LCD USB Regulator with Load Dual Timer Control for Solar Lighting System

This is a three-time controller into the evening working time,an interval of rest of pause time,Dawn working time(morning light function), the user can according to their needs,set a different time.

A:time(evening working) B:time(pause working) C:time(dawn working)

This is a compatible MPPT charge controller PWM intelligent / efficient / energy saving, it has efficient MPPT controller charging function to automatically track the maximum power point, 10% -30% higher than the ordinary controller charging efficiency, and also has standby energy saving, more than 30% energy than ordinary controller, the standby power consumption of only 10mA-15mA.
