Solar battery is the application of'storage battery'in solar photovoltaic power generation. At present, the widely used solar battery in China is mainly lead-acid maintenance-free battery and colloidal battery. These two types of batteries, because of their inherent "free" maintenance characteristics and less pollution to the environment, are very suitable for reliable solar power systems, especially unattended workstations.
With the widespread use of solar photovoltaic power generation system, as its supporting batteries, people are paying more and more attention.
Solar storage battery manufacturer also gave satisfactory answers. Solar gel batteries should have the following characteristics:
1. Better deep circulation ability, with good over-charging and over-discharging ability.
2. Long life, special process design and gel electrolyte guaranteed long life battery.
3 Suitable for different environmental requirements, such as high altitude, high temperature, low temperature and other conditions.
Working Principle of Solar Storage Battery
As a new type of clean energy, solar energy is highly praised by environmentalists. But what happens when there is no sun? Solar batteries exist for this reason.
The off-grid photovoltaic power generation system is a power generation system that converts solar energy into electric energy based on the principle of photoelectric effect. It is usually composed of solar cell modules, controllers, batteries, DC/AC inverters, etc. The function of solar cell module is to convert solar energy into electric energy, supply load to work or charge battery group; the function of controller is to protect the charge and discharge of battery group; the function of battery group is to store electric energy; the function of inverter is to convert direct current into alternating current. In the evening or rainy day, when the solar cell module can not work, the load is supplied by the battery pack.
When selecting batteries, it is necessary to understand the differences between different kinds of batteries in technology and use. First of all, it is necessary to fully understand the needs of users for products. Secondly, we need to understand the battery's performance. Different solar storage battery manufacturers produce different batteries.
