Solar Street Light with Lithium Iron Phosphate Battery

Zhengzhou Haopai New Energy Technology Co., Ltd. has many years of experience in the production of solar street lights. If there is a demand in this area, I believe it will bring you an excellent experience!

When purchasing solar street lights, manufacturers often ask customers to provide some information to determine the rationality of the various components of solar street lights. In terms of choice, the lead-acid batteries in the past have gradually been replaced by lithium iron phosphate batteries. It is said that lithium iron phosphate batteries are better. So what are the advantages of this battery and where are the advantages?

1. Improved safety performance

Batteries often fail due to overcharge and overdischarge. It is still a small matter to affect its performance. With these failures, there is often a potential explosion hazard. For example, the structure of lithium cobalt oxide battery is not stable enough, and it is at high temperature or overcharge. It is easy to collapse and heat, or form strong oxidizing substances, which affects its 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 much greater. Improved, with some safety protection devices, it will be more at ease to use.

2. 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 the characteristics will be lost after a short period of time, and it will take about one and a half years at most.

3. Stable capacity

If the battery is in an environment that is fully charged and not discharged for a long time, it will have a great impact on the capacity, because there is a memory effect. For batteries such as nickel-metal hydride and nickel-chromium, this situation is irreversible. The battery capacity is small, it is really small.

When the lithium iron phosphate battery is over-discharged to zero-voltage storage, there will be no leakage or damage, and the capacity will 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. Some other lithium-ion batteries do not have characteristics.

4. Light weight

This involves a specific energy issue. Compared with lead-acid batteries, under the same conditions, the volume of lithium iron phosphate batteries is only about 60%~70~, while the weight is only 30%~40% of lead-acid batteries. , It can save space better, and it is also proved from another level to a certain extent that under the same conditions, the capacity of the lithium iron phosphate battery is a little larger.

5. Environmental protection

This is mainly related to the disposal of the battery after it is discarded. Lead-acid batteries contain a large amount of heavy metals such as lead. If they are not handled properly, they will easily pollute the environment. However, lithium iron phosphate batteries do not contain any harmful substances, and have good performance. It is relatively stable, no matter it is in use or in the post-disposal process, it will not cause any environmental pollution.

How to install solar street light panels?

Solar street lights mainly receive light through battery panels to realize the photoelectric conversion in the back and successfully make the light source light up. If the battery panels are not installed properly, it is likely that the desired lighting effect will not be achieved.

This installation not only refers to whether the components are loose, or whether there are obstructions on the top, etc., but also the installation angle, some safety devices on the top, etc., must not be sloppy. Then, what problems should be paid attention to when installing solar street lights? ?

1. Choose the frame material

Solar energy frames are often made of some steel materials. In fact, some of the properties of these materials are not very good. To ensure their use effects, they will generally be hot-dip galvanized to improve their corrosion resistance, etc. However, some solar street light manufacturers To save costs, cold galvanizing will be used. The coating processed in this way is very thin and the corrosion resistance is not good, so pay attention to distinguish.

If it is in some coastal cities where the salt spray is heavier, it is best to choose stainless steel or heat-treated aluminum alloy, which has higher corrosion resistance and higher durability. If it is a city like Yichang, the environment is more suitable. , In the choice of the battery panel frame, you can come according to your actual needs.

In addition, in addition to choosing a good frame material, it is necessary to ensure that the frame and the foundation are welded or installed firmly to ensure that the solar panel has sufficient strength and stability to resist weather such as strong wind or snow. After all, the place where the solar panel is installed It is best to have no obstructions.

2. Find out the positive and negative poles of the components

Secondly, when installing, pay attention to clarify the positive and negative poles of the battery board, and pay attention to the polarity. If it is connected wrongly, the battery board will not work, charging can not be done, and the indicator light of the controller will not light up. Even burn out the diode, so be careful.

In addition, the wire should be as short as possible to reduce the internal resistance of the circuit, and the connection should be firmer. Do not increase the contact resistance, so that the work efficiency will be higher. In addition, you should also pay attention to the ambient temperature. According to this temperature during installation, the temperature parameters of the wire should be kept There is margin.

Three, install lightning protection device

When installing the battery panel, please also pay attention to the installation of lightning protection devices. It is especially suitable for cities where there are more thunderstorms. Otherwise, lightning strikes nearby will easily produce overvoltage and overcurrent, and the battery back will be damaged by this lightning surge.

Generally, the special photovoltaic power supply SPD is installed in the DC power distribution cabinet (combiner box), and the solar panels need to be equipotential grounding and direct lightning protection. Nanlai solar street lights have always been relatively skilled in this regard.

Four, do not wear metal jewelry

When installing the battery board, it is best not to wear metal jewelry to avoid direct contact between the positive and negative electrodes of the battery board to metal objects, otherwise there may be a short circuit, or fire, explosion, etc. may occur in severe cases.
