Yangzhou Global Solar--Introduction of lithium battery solar street light solar street

With the continuous development of lithium battery solar street light power generation technology, the application of lithium battery energy saving, environmental protection, safety and other advantages has become the new favorite of the urban road lighting industry, and the market potential is huge. In different areas, such as urban or rural areas, the requirements for the lighting density of lithium battery solar street light are different, but the working principle of lithium battery solar street light charging and discharging, and the basic characteristics of lithium battery. According to different requirements, mainly considering practicality and economy, the lithium battery solar street light configuration of the corresponding capacity suitable for the needs of the region can be selected. 1. The working principle of the solar lithium battery street light system: The solar panel receives solar radiation during the day, converts the solar energy into electrical energy and outputs it. After the integration of the solar controller, the electrical energy is stored in the lithium battery. When night falls and the working voltage of the solar panel is less than 4V, the solar controller automatically detects this voltage value, and the battery supplies power to the LED solar street light. At dawn, when the working voltage of the solar panel is greater than 4V, the solar controller stops supplying power to the LED solar street light and continues to charge the lithium battery. Second, the advantages of lithium battery solar street light are mainly reflected in the following six aspects: 1. It fully utilizes the continuous light resources of nature, has the advantages of energy saving, environmental protection, intelligent regulation, and does not need to consume the electric energy of traditional mains. 2. The charging and discharging system adopts the integrated structure of lithium battery and controller, which is a controllable and non-polluting energy storage battery system. Lithium batteries generally have a service life of up to 10 years, which can be perfectly matched with LED solar street light systems in practical applications. 3. The lithium battery solar street light can also intelligently optimize the remaining capacity of the lithium battery, the length of day and night, weather conditions and other factors according to the needs of users, reasonably allocate the power consumption level, and realize the functions of light control, time control and storage memory, etc. It can ensure that the lights are on for ten consecutive cloudy and rainy days. 4. Lithium batteries are dry batteries and are more secure. They are more stable and safer than lead-acid batteries. 5. Light weight, the weight is about 1/6-1/5 of lead-acid products under the same volume. 6. The lithium battery has strong high and low temperature adaptability, and can be used in the environment of -20℃--60℃. The above treatment can be used at -45°C. 3. Installation steps: 1. Install the triangular bracket and the sleeve bracket on the solar panel, and pass the positive and negative electronic wires of the photovoltaic puller through the sleeve (see 1); 2. Install the photovoltaic panel with the bracket installed Install it on the lamp pole, and pass the electronic wire of the photovoltaic panel through the waist-shaped hole of the lamp pole, and adjust the direction of the photovoltaic panel (sitting north to south, see 2); 3. Fix the lithium battery module on the street lamp pole On the top, the male head of the battery module electronic wire is connected with the female head of the photovoltaic panel electronic wire, the female head of the battery module electronic wire is connected with the male head of the photovoltaic panel electronic wire, and the connected electronic wire is put through the waist hole. Enter the lamp pole (see 3); 4. Install the LED lamp head, adjust the angle of the lamp head, connect the LED lamp head and the battery module with the connecting wire, and put the electronic wire into the lamp pole (see 4); 5 .After the photovoltaic panel, battery module and LED lamp head are all fixed on the lamp pole, put the lamp pole into the screw bolt and lock the screw bolt (see 5). 4. Suggestion of foundation map: Ground dragon foundation pouring: solar street light pre-buried pit specifications are 800x800x1000mm, anchor bolts should be exposed 100mm from the ground plane (see picture), and concrete should be used for pouring; when pouring, anchor bolts should be parallel to the road, The pouring surface should be leveled to prevent the lamps from tilting. The embedded parts need to be solidified before the light pole can be installed (about 4-6 days). V. Troubleshooting: 1. If it has been installed and used normally for a period of time, the LED street light will be on for 2-4 hours, and then it will no longer be on. The reason for the failure is that the photovoltaic panels are blocked by branches or other shelters, and the The light does not shine on the photovoltaic panels, and the photovoltaic panels cannot absorb energy. At this point, it is enough to remove the cover above the photovoltaic panel. 2. The LED street light does not light up all the time. The reason is that the controller inside the battery module fails. At this time, the battery module should be removed from the light pole and replaced with a new battery module.
