Yufai: The importance of batteries to 100w solar street lights

Generally speaking, the battery of 100w led solar street light is buried underground, usually placed in a buried box as an energy storage component in the solar street light system, and the underground box is usually placed next to the pole. In the cement pool, the battery and the steps that require good heat insulation and diffusion and waterproofing are very important. Nowadays, maintenance-free batteries are generally used, which basically do not require maintenance, which is very convenient. Some solar street lights can also be placed in a special welded battery box at the bottom of the pole. It is easy to disassemble, but it will affect battery life under high temperature conditions.

During the day, solar street lights are under the control of an intelligent controller. The solar panels absorb solar light and convert them into electrical energy after being irradiated by the sun. Function, it can be seen that the battery is very important to the 100w led solar street light

Advantages of choosing lithium iron phosphate battery for 100w led solar street light:

Increased safety

In the crystal structure of lithium iron phosphate batteries, the PO bond is very stable and difficult to decompose. Of course, it cannot be said that there is no danger at all. If it is used improperly, it may still be dangerous, but compared with other batteries, its safety is already great. Improved, with some safety protection devices, it will be more assured to use.

Life extension

During the discharge process, the discharge voltage of the lithium iron phosphate battery is stable and basically remains unchanged. Only when the discharge voltage is almost reached, it will change a little. It shows good discharge characteristics. The cycle life can reach more than 2000 times. It can be used. 7 to 8 years, and the cycle life of lead-acid batteries is often 300 to 500 times, and it will lose its characteristics after a long time.

Stable capacity

Lithium iron phosphate battery is over-discharged to zero voltage storage, there will be no leakage or damage, and the capacity does not change much. When you want to use it, do a few charge and discharge cycles, and the capacity can be restored to the original. This is other Some lithium-ion batteries do not have characteristics.
