The use of photovoltaic energy storage lithium batteries as energy, can obtain current, stable voltage, stable current, stable power supply, small influence by the outside world, simple structure, convenient carry, and convenient charging. It is not affected by external climate and temperature. Its performance is stable and reliable, and it plays an important role in all aspects of modern social life, and occupies a large proportion in the use of electrical energy.

At present, there are many photovoltaic energy storage lithium battery brands, including lead -acid batteries, nickel -metal hydride batteries and lithium batteries. Most factories choose lithium batteries as power supply for photovoltaic energy storage lithium batteries. Let's take a look at the advantages of photovoltaic energy storage lithium batteries compared with other batteries:

1. High -voltage photovoltaic energy storage lithium battery platform: The average voltage of a single -section battery is 3.7V or 3.2V, which is about three series of nickel -cadmium batteries or nickel -metalized batteries, which is convenient for forming a battery power supply unit.

2. Compared with the battery, photovoltaic energy storage lithium batteries have higher energy density. The energy storage density is high, reaching 460-600Wh/kg, which is about 6-7 times that of lead-acid batteries. Compared with lead-acid batteries, lithium battery weight is lighter, and the weight is about 1/5 of the same volume of lead-acid products.

3. The service life of photovoltaic energy storage lithium batteries is relatively long. The battery with lithium iron phosphate can be charged and discharged 1CDOD, which can be used 1000 times; the high and low temperature of the lithium battery can be used in high-low temperature, which can be used in the environment of -20 ° C-60 ° C. After processing, it can be used in -45 ° C environment.
