Solar street light is a new product integrated by the photovoltaic industry and the street light industry. Because it can directly use sunlight to generate electricity, and has the characteristics of energy saving, no need to lay cables, and stability, it is now widely used by us to replace traditional solar street lights. street light. However, with our extensive promotion and application, the solar street light wholesale industry is currently facing a serious quality crisis. The main components of solar street lights are the following parts: Controller The main function of the solar charge and discharge controller is to protect the battery. The basic functions must have overcharge protection, overdischarge protection, light control, time control, anti-reverse connection, charging trickle protection, undervoltage protection, waterproof protection, etc.


1) The device is selected in the selected device. At present, there are single-chip microcomputers and comparators. There are many schemes, each with its own characteristics and advantages. The corresponding scheme should be selected according to the needs and characteristics of the customer group, which will not be detailed here. described. 2) Surface treatment This series of products adopts new electrostatic coating technology, mainly FP building materials coatings, which can meet the requirements of customers for the harmony of product surface color and environment. Suitable for climatic environments. It is designed to be coated on the basis of hot-dip galvanizing, which greatly improves the product performance and meets the strict requirements of AAMA2605.2005. Other indicators have reached or exceeded the relevant requirements of GB. 3) Charging trickle protection When Yijia solar panel charges the battery, after the battery reaches the peak voltage, if the battery continues to charge at high voltage, it will easily cause the battery to lose water or run out of control; if the battery stops charging, the battery cannot be saturated.

This controller immediately drops 1V after charging to the peak voltage, and then enters the trickle charging state, which ensures that the battery can be stabilized in a full state, and at the same time avoids water loss or loss of control. Similar to cyclic charging of the battery, not only The battery is protected and the number of times the battery is charged. For example, the solar street lights in a village were all dismantled within half a year of installation; the failure rate of solar street lights in a town was as high as 50% after a few months of use; in many areas, solar lighting waste projects were directly replaced It has become an ordinary city circuit light; the maintenance of the light energy street light project is frequent, resulting in a waste of manpower, material resources and funds. What is causing these quality problems in solar street lights? For component system products, many components are assembled through parts, which gives some black-hearted solar street light wholesale manufacturers a loophole. In order to ensure the low price of products, some unscrupulous manufacturers often cut corners and shoddy manufacturing in the production process, and then bid at low prices, making the industry flooded with low-quality and low-cost garbage projects. There are no technical personnel, and there is no strong management and technical ability. The construction management cannot keep up, and the quality of the project is not up to standard, which makes the hidden projects and garbage projects in this chaotic solar street light market. Only the guaranteed price, the wholesale of solar street lights Quality can be guaranteed. Only with the right profit can there be a suitable quality assurance. The manufacturer will not do business, and the low price must be the starting point of reducing the cost of the product itself. In addition, the low price will also cause no response after the sale, and consumers will face the dual pressures of quality and after-sale after buying inferior products. Regulate the market, customize the market with reasonable prices, and resist the vicious competition of low prices. ----Solar street light manufacturers
