What is the effect of controller for solar street lamps anshan street lamp

In today's society of solar street light with the development of science and technology has been rapidly growing, more and more areas are now in the use of solar street lights, solar street light is composed of multiple components, the controller is one of the must, then the controller for solar street lamps have



in today's society the solar street lamps Solar street light is a crystalline silicon solar battery power supply, valve control type sealed and maintenance-free battery ( Gel battery) Store electricity, super bright LED as light source, lamps and lanterns and controlled by the intelligent charging and discharging controller, is used to instead of the traditional public power lighting lamps. 】 Along with the development of science and technology has been rapidly growing, more and more areas are now in the use of solar energy street lamp, solar street light is composed of multiple components, the controller is one of the must, then what is the effect of controller for solar street light? Controller is often overlooked by engineering contractor selection of a problem, the quality of the controller layer is poor not neat, 12 v / 10 a solar street lamps controller' Used in solar photovoltaic systems, solar controller it full solar charge and discharge controller, coordinate the efforts of solar panels, battery, load, is a very important component in pv systems. 】 The market price is 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 high charging efficiency of solar street light controller, with MCT 【 MCT has multiple meanings. 】 The charging mode of maximum current controller can automatically track panels, especially in winter or insufficient light, MCT charging mode efficiency is about 20% higher than the other. Three: should choose to have two way to adjust power controller, solar street lamps controller with power regulation has been widely promotion, deserted in the night time can be automatically shut down all the way or two way lighting, save electricity, can also 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 life of the battery solar street lamps, and set up the 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.
