We should how to choose and buy solar street light controller

With the development of the national new energy strategy, the use of the solar street light more and more widely. Solar street lamps controller is the core of the solar street lamp, various types of solar street lamps controller in the market now, need to pay attention to when we choose our solar street light controller

with the development of the national new energy strategy, the use of solar energy street lamp is more and more widely. Solar street lamps controller is the core of the solar street lamp, various types of solar street lamps controller in the market now, we choose solar street lamps controller need to pay attention to what?

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. To make the whole solar pv system efficient and safe operation. Solar street lamps controller is mainly used in household, commercial districts, factories, such as traffic, communication, pastoral areas in the solar power supply system. We should pay attention to when the choose and buy: a, appearance requirements

street lamp controller installed in the outdoor, and it is all-weather work, it must be moistureproof and waterproof, corrosion resistant function, the current mainstream use aluminum alloy shell, internal all glue processing.

,

charging efficiency to choose the controller with high charging efficiency and charging with MCT mode controller can automatically track panels, large current, especially in winter or insufficient lighting, MCT charging mode efficiency is about 20% higher than the other.

3, mode is the operation mode of the controller can meet the requirements of customers. Now the street lamp controller working mode generally have: pure electric, electric + control, manual mode and so on. Each controller has different characteristic, function, we must confirm carefully. Four,

power

controller working 24 hours a day, as their power consumption is bigger, will be part of the electricity consumption, select power consumption under 1 ma controller.

5, battery voltage used solar street lights are

the general points and 12 v or 24 v battery voltage. Generally low power leds to select the 12 v battery ( < 50 w) , selection of the lamps in the large power 24 v, so can effectively reduce the line loss, of course, the specifications of the battery voltage is related to solar panels and load. If solar panels and LED lights have been confirmed ok, then the battery specifications must also be suited to their specifications.
