The importance of the solar controller for solar street light

In the lamps and lanterns of solar street lights and solar garden light, solar controller has a pivotal position! Solar street light quality, directly affects the life of solar street light.

a high quality of street lamp controller should has the following functions:

1, electric automatic open and shut down, regular shutdown, 2, 4, 6, 8, 10, 12 hours) ;

2, PWM three sections of the charging control with temperature compensation function, more than a simple controller to improve the charging efficiency 30%;

3, single/double lamp work mode selected;

4, battery SOC discharge process automatic control ( Greatly improve the ability to resist the continuous rainy days, prolonging the life of the battery also) ;

5, battery over discharge protection;

6, the counter-attack filling, meter, over current and short circuit protection, etc. ;

7, manual reset program.

in the combination of solar street lamps, in addition to the light source, street light controller is also very important parts. Solar controller includes: the effect of light-operated switch machine, lamp work timing, control of battery charging and discharging, single/double lamp mode control, the battery capacity monitoring, as well as the short circuit, over-current, prevent the reverse polarity, the counter-attack, line lightning protection and other protection function. Controller design and quality is directly related to the efficiency and reliability of street lamp.
