3 SYSTEM When the sun light has growing at dawn, solar controller knows the morning, they turn off the LED lights, and starting MPPT tracking to the solar panels, also then charge the battery. In the afternoon, as the battery voltage is getting higher and higher, MPPT controller has constant voltage charging, in the evening, the charging current has smaller and smaller, and finally into the constant voltage float. As the light has weak and weak, the solar charger knows to stop charging and then drive LED, this means Discharging has entered to the first time period, they drive LED lights has as per the drive current at first time period; Then charging has enter to the second time period, they drive LED lights has according to the drive current at second time period; finally into the third time period, they drive LED has according o the third time period current, it can discharge to the third time period or dawn.
