How to distinguish between good and bad lithium battery integrated solar street lights?

Whether it is on the main road in the city, on the small road in the country, in the factory or in the community, we can always see the figure of the lithium battery integrated solar street lamp, it is so widely used in our lives, to do the lithium battery integrated There are more and more manufacturers of solar street lights, which makes it easy for consumers to make difficult choices.

So how do we choose a lithium battery integrated solar street light, and distinguish the quality of lithium battery integrated solar street light, can be selected from the following three aspects.

1. How to choose a solar panel for lithium battery integrated solar street light

First of all, we have to determine the photoelectric conversion rate (conversion rate u003d power/area) of the solar panel of the lithium-electric integrated solar street light. The panel is closely related to this parameter. There are two types of monocrystalline silicon and polycrystalline silicon. Generally speaking, polycrystalline silicon The conversion rate is usually around 14%, and the highest can only reach 19%, while the conversion rate of monocrystalline silicon can be as low as 17% and as high as 24%.

Second, how to choose a lithium battery integrated solar street lamp solar battery

A good lithium battery integrated solar street lamp must ensure sufficient lighting time and lighting brightness. To achieve this, the requirements for batteries are naturally not low. At present, there are mainly lead-acid batteries (gel batteries) and iron phosphate on the market. There are two types of lithium batteries. The traditional lead-acid battery has stable voltage, relatively cheap price, and relatively simple maintenance. However, this battery has low specific energy and short service life, and requires frequent daily maintenance.

The rapid development of lithium iron phosphate batteries has obvious advantages in terms of depth of discharge and charging time, and is relatively adaptable to the environment. The volume and weight of lithium iron phosphate batteries are also smaller than those of lead-acid batteries. The construction is easier and the effect is better. Therefore, lithium iron phosphate batteries are the best choice in terms of batteries. Nanlai solar street lights use all lithium iron phosphate batteries. , The lighting time is long, and the brightness is bright enough.

3. How to choose a solar controller for integrated lithium battery solar street light

In the solar power generation system, the solar controller of the lithium battery integrated solar street lamp is a device that controls the solar battery to charge the battery to supply power. It works uninterrupted throughout the day, and its own power consumption is best controlled below 1mAh to avoid excessive consumption Electric energy affects power generation efficiency. The controller should preferably have a three-stage charging control mode of strong charging, balanced charging, and floating charging to ensure the power generation efficiency.

In addition, the controller should have the function of two separate control, so that the power adjustment of the street lamp can automatically turn off one or two lights during the time when there are few pedestrians on the road, which is beneficial to saving electricity. This accessory Manufacturers usually bring them back through outsourcing for assembly and deployment.

In short, although the lithium battery integrated solar street light is good, there will always be some counterfeit and inferior products on the market, which will bring troubles to the use process. When choosing, we must investigate in many ways. Electronic Technology Co., Ltd. will help you choose high-quality products. The product.
