Features:
More compatibility with a variety of storage batteries such as VRLA battery, gelled electrolyte (GEL) Battery, 3.2V x 2 iron-phosphate-based lithium batteries 3.2V x 4 iron-phosphate-based lithium batteries, 3.7V x 1 iron-phosphate-based lithium battery.
Prevent storage battery being overcharged, over discharged and back discharged at night and it also has PWM charging protection.
Automatically turn on floodlight according to the lightness at sunset. Regularly turn off floodlight according to the set value or automatically turn off according to the lightness at sunrise. 9 grades can be adjusting for the controlling light sensitivity, by using the parameters, users can control the time of lighting on in the evening or lighting off at dawn, Besides, it has the half-power adjustable acharacteristics (9 grades with different power or brightness can be set to save electricaity).
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.
Open circuit is used for anti-overcharge protection, which effectively protects solar panel.
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.
