Solar power storage batteries is the application of ‘battery’ in solar photovoltaic power generation. At present, there are four kinds of lead-acid maintenance free battery, ordinary lead-acid battery, colloidal battery and alkaline nickel cadmium battery. At present, the widely used solar batteries in China are mainly lead-acid maintenance free batteries and colloidal batteries. Because of their inherent “maintenance free” characteristics and less pollution to the environment, these two types of batteries are very suitable for reliable solar power supply systems, especially unattended workstations.

The solar power storage batteries shall have the following advantages:

1.Solar energy resources are inexhaustible.

2.Green environmental protection. Photovoltaic power generation itself does not need fuel, has no carbon dioxide emission and does not pollute the air and no noise.

3.Wide range of applications. Solar power generation system can be used wherever light can be obtained. Which is not restricted by geographical, altitude and other factors.

4.No mechanical rotating parts, simple operation and maintenance, stable and reliable operation. As long as there is a solar cell in a photovoltaic system, the battery module will generate electricity. In addition, it now adopts automatic control number, which basically does not need manual operation.

5.Solar cell production materials are abundant: silicon materials are abundant, and the abundance of the earth’s crust ranks second after oxygen, up to 26%.

6.Long service life. Crystalline silicon solar cells can last up to 2035 years. In the photovoltaic power generation system, as long as the design is reasonable and the type selection is appropriate, the service life of the battery can also be as long as 10 years.

7.The solar cell module has the advantages of simple structure, small and light volume, convenient transportation and installation, and short construction cycle.

8.Easy system combination. Several solar cell modules and battery cells are combined to a solar cell array. Inverter and controller can also be integrated. The system can be large or small, which is very easy to expand.

9.The energy recovery period is short, about 0.8-3.0 years; The energy increment effect is obvious, about 8-30 times.

Working principle of solar power storage batteries

During the day, the sunlight shines on the solar module to generate a certain range of DC voltage, convert the light energy into electric energy, and then transmit it to the intelligent controller. After the overcharge protection of the intelligent controller, the electric energy transmitted from the solar module is transmitted to the battery for storage; Storage requires storage battery, which is an electrochemical equipment that stores chemical energy and releases electric energy when necessary.

Use and maintenance of solar power storage batteries

(1)Suitable working temperature: 15 ~ 20 ℃

(2)The solar power storage batteries is connected by connecting the positive pole and the positive pole, and the negative pole and the negative pole. In this way, the power of the solar power storage batteries will double, and the voltage is the same as that of batteries. The two poles shall not be short circuited (bumped).

(3)Keep the battery clean. The installed solar power storage batteries pole shall be coated with vase line to prevent corrosion of the pole.

(4)Configure on-line monitoring and management technology for solar power storage batteries, measure and analyze the internal resistance of solar power storage batteries on-line, find the defects of battery in time and maintain it in time.

(5) Prevent the solar power storage batteries from frost cracking in winter and direct sunlight in summer. The batteries should be placed in a ventilated, shady and cold place.
