The quality of the solar street lamps controller affecting the service life of street lamps

The choice of solar street light controller is often overlooked by engineering contractor of a problem, the quality of the controller layer is poor not neat, 12 v / 10 a controller market prices in 100 - Is 200 yuan, although the value of the smallest part of the whole street lamp system, but it was very

the choice of solar street lamps controller is often overlooked by engineering contractor of a problem, the quality of the controller layer is poor not neat, 12 v / 10 a controller market prices in 100 - 200 yuan, although is the minimum value in the street lamp system, but it is a very important link. Controller is good or bad will directly affect the life of components of solar street light system and the purchase cost of the whole system, one: should choose low power consumption controller, the controller working 24 hours a day, as their power consumption is bigger, will be part of the electricity consumption, had better choose power consumption in 1 ma ( MA) The following controller. 2: choose a controller of high charging efficiency and charging with MCT model of maximum current controller can automatically track panels, especially in winter or insufficient lighting, MCT charging mode efficiency is about 20% higher than the other. Three: should choose to have two way to adjust power controller, adjust the power controller has been widely promotion, deserted in the night time can be automatically shut down all the way or two way lighting, save electricity, LED lights, LED lights for power regulation. In addition to select the saving function, but also should pay attention to the protection function of controller for battery and other components, as has a trickle charge mode controller can very good protection batteries, increase the service life of battery, the other set controller under-voltage protection value, as far as possible the under-voltage protection value in 11 or higher. 1 v to prevent the battery discharge.
