OLYS teach you how to quickly choose solar charge controller

       Choose solar charge controller, according to the current in generally  and panel current much more than load current ,so we refre to solar panel current. For example, the load is 60 W,panel 100W,battery 12V,60W/12V=5A,100W/12V=8.333A,so you should choose charge controller 12V / 10A. You want the lights in the first 5 hours of full power, after midnight half power, then you have to choose with half the power of the controller; you need to light from the dark to 0:00, 0:00 automatically shut down the load, 4 o'clock Bright dawn, you can choose a dual controller!

       Solar street light controller is mainly used for solar garden lights, commercial street, factory park roads, traffic lights, landscape lights, pastoral areas, unattended communication base stations and other solar lighting and power supply system.

As a solar street light controller should have the following basic functions: to the best charge to the state of the battery charge, automatically turn on and off the street or load, with overload protection, short circuit protection, reverse discharge protection, polarity reverse polarity protection, Lightning protection, undervoltage protection, overcharge protection, load start recovery settings.  

The choice of solar controller noted:

一:Should choose a lower power controller, the controller 24 hours of continuous work, such as its own power consumption, it will consume part of the power, the best choice of power consumption below 3 mA controller.  

二:To select the controller with high charging efficiency, the controller with strong charge, balanced charge and float charge is controlled by MCU, and it can always charge the battery with the maximum power, especially in the winter Or under light of the period, the use of MCU intelligent control of the charging mode than non-MCU intelligent controller about 20% higher efficiency.

三:With high-precision control, high-precision product design is a comprehensive embodiment of the material is also a good expression of material, it is the embodiment of the production process. Non-high-precision control of the solar street light controller is often due to product design is unreasonable, poor selection of materials such as the use of high repair rate, poor reliability, low market prices.

四:only the choice of two separate control with the controller, so easy for the entire lamp power adjustment. In the night pedestrian rare period can automatically turn off all the way or two lighting, saving electricity, you can also for LED lights for power adjustment. In addition to selecting the above power saving function, set the controller undervoltage protection value, try to put the undervoltage protection value ≥ 10.8V, to prevent the battery over discharge.

Wiring method:

General solar controller should first connect the battery line, followed by connecting the lamp line, and then cover the battery with a black cloth, and then connect the solar panel line。
