Correct maintenance of solar street lightsolar street light-li

In addition to panels and controllers, inverters, and electric equipment, solar lighting equipment is much more complex than sodium lamps. Therefore, in order to ensure that solar lighting equipment continues to operate, inspection and maintenance are usually performed on a weekly basis. A comprehensive inspection of equipment is carried out every fall, especially cleaning and polishing of lighting fixtures and some solar modules. Solar lighting systems that do not solve the photoelectric conversion rate, the volume of the battery and the main problems, such as the number of life and maintenance, will far exceed the maintenance of high-pressure sodium lamps. Correct maintenance of solar street light: 1. When there is wind, rain, rain, hail, snow, etc., measures should be taken to protect the solar cell array to avoid damage. 2. Wind, rain, snow or steering immediately check whether the board is after the rainy season, whether the control room and the battery are indoor water, water, after the storm should check whether the equipment is working normally, its charge and discharge controller is damaged, etc. 3. The lighting of the solar cell array should always be kept clean. If there is dust or other dirt, it should be washed first, and then wiped gently with clean gauze water. Do not use hard objects or corrosive solvents to rinse or heuristic. 4. When using the battery with the solar cell array, the use and maintenance methods of the battery should be strictly followed. 5. Check the power system connected to the solar street light to avoid loose connection. 6. Check the grounding resistance of the solar street light. The design of the solar street light system is not static. It usually needs to be designed according to the specific conditions of the location. There are many factors that affect the configuration plan, such as average sunshine time, road width, required daily discharge time, and the longest continuous rainy days. Let's take a specific example below: 1. LED solar street light, single-channel, 40W, 24V system; 2. The local average daily effective illumination is calculated as 4 hours; 3. The daily discharge time is 10 hours, (from 7:00 pm to 5:00 am For example) 4. 5 days of continuous rainy days (plus the electricity consumption of the night before the rainy days, 6 days). Current u003d 40W÷24V u003d 1.67 A Calculated battery u003d 1.67A × 10h × (5 + 1) days u003d 1.67A × 60h u003d 100 AH Battery charge and discharge reserve 20% capacity; the actual current of the street lamp is above 2A (plus 20% loss , including constant current source, line loss, etc.) Practical battery needs u003d 100AH u200bu200bplus 20% reserved capacity, plus 20% loss. 100AH u200bu200b÷ 80% × 120% u003d 150AH practical battery is 24V /150AH, two sets of 12V batteries are required, total: 300AH
