Introduction
Solar charge controller is a device which can make the battery
work in a normal scope of voltage and current, it can effectively
control battery charging from the solar panel, influence the life
of battery and system effectiveness
Solar controller has 3 charging steps (quick charge-equalizing
charge-floating charge), built-in temperature compensation, LED
indication light, warming of buzzer and perfect protection of ov-
erload, over charge, low voltage, short circuit and so on. The ap-
plication of advanced computer chip and contactless
control technique ensure the safety and reliability of the solar e-
nergy power supply system.

Note: The controller have no enclosure, if it is in the system.

Characteristics:
1. LED/LCD indication mode: functional mode & accumulator voltage
2. Warming: low-voltage for buzzer and reverse connection for battery
3. Over or low-voltage protection and PWN circuit control
4. 3 steps of charging ways and built-in temperature compensation
5. Nice protection of overload, short circuit an polarity reversed without the external fuse
