Functions: 1. More compatibility with a variety of storage batteries. 2. Prevent storage battery being overcharged, over discharged and reverse discharged at night and it also has PWM floating-charged protection. 3. Automatically turn on floodlight according to the lightness at sunset. 4. The tandem type PWM charge control is used, which makes the charging circuit of the voltage loss is only 1/5 of the diode's, the charging efficiency is 3% to 16% higher than non-PWM and the power utilization time is longer. Power MOSFET is also used for preventing the battery discharge reversely through the battery plate, which reduces the charge loss. 5. Open circuit is used for anti-overcharging protection, which effectively protects solar panel. 6. Automatically memorize various parameters set by the users, and the data will not lose in the situation of unexpected power failure or the battery power is used up.
