In our lives, for the street lights, we should be quite a number of contacts, and we contact the street lights are now generally used in solar street lights, that since the use of solar street lights so widely because there is a unique feature
The advantages of solar street lights
1. Solar street light using solar photovoltaic cells to provide electricity, solar energy as a green new energy, "inexhaustible, inexhaustible." Make full use of solar energy resources, Solar LED Street Light to alleviate the conventional energy shortage situation has a positive meaning.
2. The installation of solar street light is simple and convenient, without the need for ordinary street lights as laying a large number of basic projects such as cable, Solar LED Street Light only need to have a base fixed, all the lines and control parts are placed in the lighthouse, forming a whole.
3. The operation and maintenance of solar street lights is low. The entire system operation are automatic control, without human intervention, almost no maintenance costs.
The "Big Four" Protection Mode of Solar Street Light
Mode one, direct charge protection point voltage
Direct charge also called emergency charge, are fast charge, are generally in the battery voltage is low when the use of high current and relatively high voltage on the battery charge, Solar LED Street Light but there is a control point, also known as protection points.
Direct charge protection point voltage is generally "overcharge protection point" voltage, the battery voltage when charging the battery can not be higher than the protection point, Solar LED Street Light otherwise it will cause overcharge, the battery is damaged.
Mode two, are charged control point voltage
Direct charge after the end of the battery will be charged and discharged controller for some time, so that the voltage naturally fall, when the fall to the "recovery voltage" value, will enter the state are charged.
Are charged, that is, "balanced charge." Are charged time should not be too long, usually for a few minutes to ten minutes, the time set too long but harmful. For a small system equipped with two batteries, Solar LED Street Light it is not meaningful. and so. Solar street light controller is generally not full charge, only two stages.
Mode three, float control point voltage
Usually after the charge is completed, the battery is also standing for some time, so that the end voltage naturally fall, when the drop to the maintenance voltage "point, it entered the floating state. Similar to a small current charge, the battery voltage is low to charge On a little, Solar LED Street Light a low to charge a little, an share to, so as to keep the battery temperature continues to rise, which is very good for the battery.
Mode four, over discharge protection termination voltage
Battery discharge can not be less than the national standard. Although the battery manufacturers also have their own protection parameters, but ultimately to move closer to the national standard.
For safety reasons, the general 12V battery over the protection point voltage plus 0.3v as a temperature compensation or control circuit zero drift correction, Solar LED Street Light so 12V battery over discharge protection point voltage is: 11.10v, then the 24V system over discharge The protection point voltage is 22.20V.
