Solar garden lights pointed out that 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, reverse connection, charge current protection, undervoltage protection, waterproof protection, etc. 1) Equipment selection In the equipment selection, there are currently single-chip microcomputers and comparators. There are many solutions, and each solution has its own characteristics and advantages. Choose the corresponding solution according to the needs and characteristics of the customer group. 2) Surface treatment Using new electrostatic coating technology, mainly FP professional building material coatings, solar garden lights can meet customers' requirements for product surface color and environmental harmony. At the same time, the product has high self-cleaning properties, strong corrosion resistance and aging resistance, and is suitable for any climatic environment. When the solar panel is charging the battery, after the battery reaches the peak voltage, if you continue to charge the battery with high voltage, it is easy to cause the battery to lose water or lose control; if you stop charging, the battery cannot be saturated. The controller drops 1V immediately after charging to the peak voltage, and then enters the flow charging state. The solar garden lamp manufacturer ensures that the battery can be stabilized in a fully charged state, while avoiding water loss or loss of control. This is similar to charging a battery. Not only is it efficient, but it can also protect the battery and increase the number of battery recharges, thereby extending its service life. solar garden lights oem uses solar energy as a power source to provide night road lighting. It uses a high luminous efficiency light source design, light control and time control, high brightness, easy installation, stable and reliable work, no cables, no conventional energy consumption, and long service life. The long-term advantage belongs to the green energy product, which is strongly advocated by today's society. The solar garden lights oem itself is highly decorative, and also emphasizes the harmony of the landscape of artistic lights, the history and culture of scenic spots and the surrounding environment, and uses different shapes, different light colors and brightness to create the scenery. solar garden lights oem is mainly used for lighting and lighting decoration of urban roads, residential roads, industrial parks, parks, roofs, green belts, squares, pedestrian streets, fitness and leisure squares and other places.
