Installation steps of solar street lamp battery

First of all, let's understand the working principle of solar street lamp battery. During the daytime sunlight shines on the solar panel, so that the solar panel generates a certain range of DC voltage, converts the light energy into electric energy, and then transmits it to the controller. After the overcharge protection of the intelligent controller, the solar module is transmitted. The electric energy is sent to the storage battery for storage. At night, the solar battery will deliver the stored electricity to the LED lamps.

　　 Solar street lamp battery installation:

　　First: Check whether the battery compartment is damaged, and check whether the battery voltage is normal. If there is an abnormality, it will be judged as a non-conforming product and installation is prohibited. Wrap the two poles of the sheath wire with insulating tape.

　　Second: Clear the soil and other debris in the cement tank where the battery compartment is placed in the foundation of the solar street light to ensure that the drainage hole is not blocked by foreign matter.

Third: disassemble and assemble the battery compartment and use a crane to put it into the pre-built foundation, and then put two double steel wire hoops on the connecting hose, and then pass the battery cable through the prefabricated pipe of the ground cage, and the prefabricated pipe Spread a layer of 7091 sealing silica gel evenly on the top and insert the other end of the connecting hose into the root of the prefabricated pipe, and fasten the bolts on the double-wire type hoop with a flat-blade screwdriver. After the battery cable is threaded out of the prefabricated tube, put on a section of threading hose, put two double steel wire hoops on the threading hose, and evenly coat the prefabricated tube with a layer of 7091 sealing silicone, then the thread will be soft. Insert the tube into the root of the prefabricated tube, use a flat-blade screwdriver to fasten the bolts on the double-wire hoop, and finally fix the battery wire to the tube opening.

　　Fourth: charging trickle protection

　　 When the battery is charged by the solar panel, after the battery reaches the peak voltage, if the battery continues to be charged with high voltage, it will easily cause the battery to lose water or run out of control; if the charging is stopped, the battery cannot be saturated. This controller immediately steps down 1V after charging to the peak voltage, and then enters the trickle charge state, ensuring that the battery can be stabilized in a full state, while avoiding water loss or loss of control, similar to cyclic charging of the battery, not only efficient It protects the battery, and also increases the number of charging of the battery, and the service life is longer.

Which solar street light battery is better?

Solar street lamp batteries are the main equipment of solar street lamps. At present, the batteries used in solar street lamps mainly include lead-acid batteries, gel batteries, ternary lithium batteries, and lithium iron phosphate batteries. So which battery is the best for solar street lamps?

First of all, let's take a look at the characteristics of these types of batteries:

1. Lead-acid batteries: The plates of lead-acid batteries are made of lead and lead oxides, and the electrolyte is an aqueous solution of sulfuric acid. Its main advantages are stable voltage and low price; the disadvantage is that the specific energy is low (that is, the electric energy stored in the battery per kilogram), so the volume is relatively large, the service life is about 300-500 deep cycles, and the daily maintenance is frequent. At present, solar street lights The industry is still heavily used.

2. Gel battery: In fact, it is an upgraded and maintenance-free version of lead-acid batteries. It replaces sulfuric acid electrolyte with gel electrolyte, which is better than ordinary batteries in terms of safety, storage capacity, discharge performance and service life. To improve, the price is even higher than that of ternary lithium batteries. It can be used in the temperature range of -40°C to 65°C, especially with good low temperature performance, suitable for the northern alpine region. It has good seismic performance and can be used safely in various harsh environments. The service life is about twice as long as that of ordinary lead-acid batteries.

3. Ternary lithium battery: higher specific energy, small size, fast charging and higher price. The number of deep cycles of ternary lithium battery is about 500-800 times, the life span is about 1 times longer than that of lead-acid battery, and the temperature range is -15℃-45℃. But the disadvantage is that it is not stable, and the ternary lithium battery of unqualified manufacturers may explode or catch fire when overcharged or the temperature is too high.

4. Lithium iron phosphate battery: high specific energy, small size, fast charging, long service life, good stability, and of course the highest price. The number of deep-cycle charging is about 1500-2000 times, the service life is long, generally up to 8-10 years, the stability is strong, the use temperature range is wide, and it can be used at -40℃-70℃.

In summary, of course, solar street lights use lithium iron phosphate batteries, and the cost performance is also the highest. Therefore, lithium batteries have become a king among solar street lights!
