Battery is one of the main components of photovoltaic power plants for energy storage, the upcoming solar energy batteries supplied into chemical energy stored in them. Usually during the day to charge the battery by the solar cell matrix, nighttime power to the load from the battery, solar battery charging in a semi-floating state.
To make the battery system has high reliability, we must first correct choice of batteries, UPS batteries and communication in the design there are different: Some batteries have better cycle characteristics; some battery suitable for start-up; some battery suitable for low-temperature environment; Some battery suitable for low current discharge and so on.
In the selection of batteries, battery on understanding the various differences between the process and the use is necessary, we must first fully understand the needs of users of the product itself. Such as back-up power system capacity requirements, frequency of use, the use of the environment, the main purpose, service life, reliability, instantaneous discharge rate, rectifiers battery specifications and other relevant performance requirements.
Second, we must understand the electrical performance of the battery, including product design parameters (battery model, the appearance of size, rated capacity, rated voltage, the weight, the weight ratio of the energy, the volume ratio of energy, design life, the number of positive and negative plates sheet, positive and negative plates thickness ratio, the electrolyte density, type plates, plate gate materials, etc.), the product electrical performance parameters, the actual life of the product, installation environment, different types of performance and price, different types of product warranty period, etc.
