Batteries store the electricity generated by the solar panel during the day and provide power to the unit at night. Battery life is very important to the life of a flashlight, and battery capacity affects the number of days a flashlight can run on its own. Solar LED street lights typically use 3.7V rechargeable batteries.The battery life of the solar lighting system is up to five years. The configuration of each luminaire is such that the solar panel fully charges the battery in 1 sunny day, and the built-in battery provides an overnight backup without recharging. This kind of street lighting basically integrates a lithium battery and a solar battery in an LED street light housing, but a separate solar panel on the outside.The integrated solar panel converts solar energy into electric energy, which is stored in the built-in battery for lighting from dusk to dawn. The solar lighting system is controlled by built-in intelligence without manual operation, which is safe and economical. We have seen how to install an integrated solar lighting system. Modern solar street lights have built-in solar panels, built-in lithium-ion batteries, battery management systems, night and motion sensors, and automatic control.It also boasts a versatile solar lighting design with a SMART wireless dimming mechanism. It is designed in such a way that it automatically adjusts the brightness level according to the traffic on the road. It is the first in-house motion sensor and built-in lithium-ion battery for outdoor lighting. It is also ideal for various weather conditions as it can absorb a lot of solar energy.During the day, it stores energy generated by solar panels and then discharges to supply energy to a solar street light when there is not enough light or at night. It has three options, namely LI4 , LI5 , LI6 , and all of these options differ from each other depending on the system power, battery size, solar panel power, pole height and the area each light can cover. Determine the number of hours it takes to charge your solar lights. It should provide backup power on days with low solar intensity.Photovoltaic panels charge a battery that powers the LED lamp at night. In countries with a lot of sunlight, solar lanterns are the best option for illuminating streets, gardens, parks and other public places. Well, this amazing solar street light has an intelligent control system that adjusts the light intensity according to your lighting needs.This amazing street light uses LED light source and has a compact and elegant design. The solar panel, battery and light source of this amazing multifunctional device are unified. In essence, the multifunctional solar street light combines solar panels, LED bulbs and lithium iron batteries under one roof to form a single product. One of the main players in solar street lights is Intelizon solar street lights. Intelizon uses lithium-ion batteries combined with LEDs and solar energy to create cutting-edge technology products for indoor and outdoor lighting.Xinxing Street Light is a modern multifunctional product under Jiangsu Suoguang Solar Lighting Co., Ltd. Like most well-known manufacturers of solar street lights, the company uses LEDs and lithium batteries. We provide two-piece built-in solar LED street lights with built-in lithium-ion or lithium iron phosphate batteries, and LED panels of various sizes from 9W to 15W. EG series is a reliable solar lighting solution with excellent light quality, suitable for outdoor use. The built-in lithium-ion battery prevents the battery from being stolen. The 150 Im/W LED with improved lens can provide up to 50% of the light intensity per watt.The power consumption of the LED luminaire is at least 50% lower than that of its HPS counterpart, which is widely used as a light source in traditional street lighting. Traditional street lights use direct current, which means that a converter is required to convert AC to DC power, which causes energy waste. Otherwise, the LED uses alternating current, which means the final output is extremely efficient. LEDs have the best lumen / watt ratio, making solar street lights the best lighting solution in the world.After the solar pole lights are installed and everything is working, make sure you have installed the built-in solar street light successfully. So you don't have to be afraid to buy all in one solar parking light for sale. Well, any seasoned solar panel installer will confidently advise you on a product with higher brightness and longer battery life.For some high-quality solar street lights, if three lithium batteries are used, professional manufacturers will use 11.1V systems (three 3.7V batteries), with a capacity of at least 3 times that of 3.7V, and of course the price will be lower. above. The lithium iron phosphate battery has a life of more than 5 years and does not need to be replaced during use. If you need high quality or use at low temperatures, GEL battery solutions will be your best choice. 5. Lithium batteries are more adaptable to the environment and have a wide range of operating temperatures. They can be used in an environment of -20-60 degrees. After technical treatment, they can also be used in an environment of -45 degrees. This also provides for the use of lithium batteries. Conditions to promote solar street lights in cold areas.Built-in rechargeable lithium battery is integrated into the lamp body; If you choose an outdoor type of support on a pole, it is better to install the equipment on a 6 meter high solar street lamp, while there should be no objects for climbing next to the solar street lamp, also pay attention to the anti-theft one. If you choose an underground type, it is better to pay attention to anti-theft, water resistance, dense concrete pouring, replaceability.Usually the battery is buried in the ground or placed on a lamp post. Solar cells can also be called accumulators or accumulators. The nominal voltage of a single-cell lead-acid battery is 2.0V and can be discharged. When it reaches 1.5V, it can be charged to 2.4V; in solar street light systems, multiple single-cell lead-acid batteries are often connected in series to form a lead-acid battery with a rated voltage of 12V or 24V, 36V and 48V.You can read this chart to determine how many watts of solar LED bulb you should be using. One is to use a U-shaped mounting bracket to make it easier to attach your outdoor solar system to a pole that supports a 0 to 15 degree lamp tilt adjustment. Optional bluetooth remote control that allows on / off control, dimming and sanitary control of LED devices.At the same time, keep it away from the shadows of the house, trees, etc. Continue to clean the surface of the universal solar street light with regular detergent for maximum power, remove dust, tree leaves or any grease. Built-in fuse holder on the body of the flashlight, remove the insulating film before use, one 5A (220V) fuse is offered as a backup.
