Application
Solar Charge Controller can be used in maximum solar panel Spec 18V/40W (maximum open circuit voltage 23V), the maximum load Spec 12V/36W solar LED lights and other types of application systems, more details behind the (type of load description) this chapter.
Feature
1.More compatibility with a variety of storage batteries such as VRLA battery, galled electrolyte (GEL) Battery, 3.2V*2 iron-phosphate-based lithium batteries 3.2V*4 iron- phosphate-based lithium batteries ,3.7V*3 lithium batteries,3.7V*2 lithium batteries, 1.2V*6 Ni-MH batteries, 1.2V*3 Ni-MH batteries, 3.7V*1 lithium battery and 3.2V*1 iron- phosphate-based lithium battery.
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. 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 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 characteristics (9 grades with different power or brightness can be set to save electricity).
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.
7. low static power consumption:The controller uses the latest low-power component, the minimum static power as low as 2mA.
8. adjustable brightness:Typically solar warning lamp brightness is fixed, sometimes found in the sun during the day and feel the brightness is too low is not obvious, but if you increase the brightness will result when too glaring at night, sometimes it is not conducive to traffic safety. The controller can be adjusted by setting the lamp power (dimmable half power P1-P9) the night lights brightness reduced to 10%-90%, soft light without glare, while saving electricity in order to support more rainy days, the during the day maximum brightness with full power in order to achieve optimum warning effect, more humane. For aviation obstruction lights can also be adjusted to P8, P9, which uses pulse groups luminous way, using the human eye principle of [persistence of vision], save more power.
Voltage Data for Various types of storage batteries:
>> Notice: If you use 6V batteries, please match 9V solar panel for your system. If you use 12V batteries, please match 18V solar panel for your system. Controller can auto sensing these two systems to choose the best charging methord to your battery. These two systems shouldn"t be mixed, otherwise the controller may work abnormally.
Directly use wires (22#AGW) to connect the solar panels, storage battery and load according to the flow chart of controller panel and pay attention to match red line with positive pole and black with negative pole.
>>Notice: The controller should be installed in a waterproof bag, the traces of photovoltaic panels and load lights should go as "U"arc-shaped under the controller and be fixed well to avoid the rain directly flowing into the controller along with the electric wire, and each connection joint should be wrapped up well with water-proof insulating tapes.
