What is the battery of solar street lights?

1. What battery is used for Solar street lights

Solar street lights are environmentally friendly street lights that use solar energy to power on street lights. Generally, solar energy is a crystalline silicon Solar cell power supply. The battery stores electrical energy. There are four commonly used batteries:

1. Lead -acid battery

The pole plate of the lead -acid battery is composed of lead and lead, and the electrolyte is a hydraulic solution of sulfuric acid.Its main advantage is that the voltage is stable and the price is cheap; the disadvantage is that it is lower than energy (that is, electrical energy stored per kilogram of battery), so the volume is relatively large, the service life is about 300-500 deep cycles, and the daily maintenance is frequent.The industry is still used in large quantities.

2. Collagen battery

Collagen battery is actually a upgraded maintenance version of lead -acid batteries. It is replaced with colloidal electrolytes to replace sulfate electrolytes. It has improved in terms of safety, power storage capacity, discharge performance and service life.Some are even higher than the ternary lithium battery.It can be used within the temperature range of -40 C-65 C, especially the low temperature performance is good, suitable for high-cold regions in the north.Seismic resistance is good and can be used safely in various harsh environments.The service life is about doubled than the ordinary lead -acid battery.

3. Tricss lithium battery

Higher, small, fast charging, high price.The number of deep cycles of ternary lithium batteries is about 500-800 times, and the life span is about 1 times longer than the lead-acid battery, and the temperature range is -15 C -45 C.However, the disadvantage is that it is not stable. The ternary lithium battery of the unqualified manufacturer may explode or fire when the temperature is over -charging or the temperature is too high.

4. Lithium iron phosphate battery

Higher, small, fast charging, long service life, good stability, and of course the highest price.The number of deep-loop charging is about 1500-2000 times, and the service life is long, which can generally reach 8-10 years. The stability is strong, the use temperature range is wide, and it can be used at -40 C-70 C.

2. How much is the battery of Solar street lights

The battery voltage of Solar street lights is generally between 12 volts and 24 volts, and it is a DC voltage.The related component configuration of Solar street lights is:

1. 24VLED: Choose LED lighting, LED lights have long service life, soft light, and reasonable price. It can be adjusted during the scarce time of night pedestrians, which is conducive to power saving, which can reduce the configuration of the battery board and save costs.About 80-105LM per tile, light failure is less than year 5%.

2, 12V battery (string 24V): Choose lead acid to maintain the battery, moderate price and stable performance.

3. 12V battery board (string 24V): The conversion rate is more than 15%single crystal positive film.

4, 24V controller: MCT charging method, briefing function.
