What should be paid attention to when choosing 3.2V solar street light?

As the government continues to deepen the construction of beautiful villages, solar street lights are more and more widely used in the construction of new countryside. The construction of beautiful villages, and solar street lights must be chosen for outdoor road lighting have also become a new trend in the construction of new villages.
At present, there are mainly two types of solar street lamps with voltages of .V and V on the market. Compared with the V system, the .V solar street light is cheaper, but the quality is more 'mixed


1. The choice of .V lithium battery cells.
On the market, .V solar lithium batteries mainly include pointed lithium iron phosphate batteries eliminated by automobile factories and non-eliminated flat-head lithium iron phosphate batteries. The pointed lithium iron phosphate battery has fewer cycles and a short service life. Although the solar street lamp made of this battery is cheap, this .V solar street lamp has many disadvantages. The cycle times of the flat-head lithium iron phosphate battery cell can be up to two, so the life of the .v solar street lamp using this battery cell is longer and the profit can be used for up to a year.
2. The choice of .V solar street light controller.
.V solar street lights can use flat pressure solar controller and boost solar controller. If it is matched with a flat pressure controller, the maximum lighting power of the solar street light can only reach W. This kind of controller is suitable for solar street lights with a height of meters to below meters. If you want a solar street lamp with a height of more than meters to have a better lighting effect and greater lighting power, then you can only choose a boosted solar controller, which can make the lighting power reach the level you want. However, the price of a boosted solar controller is more than double the price of a flat-pressed solar controller.
3. Regional temperature
Since lithium iron phosphate batteries are not resistant to low temperatures, the light will not turn on when the temperature is below zero, so it is only used in the southern region.


Combining the above two precautions, we can draw this conclusion: .V solar street lights use flat-head lithium iron phosphate batteries and boost solar controllers, which not only have a good lighting effect, but also exceed V solar in terms of service life. Street lights, and the overall price will be more favorable than V solar street lights, but if the price is too cheap, we must be careful that solar lithium batteries may be used out of lithium iron phosphate batteries.
