With the rapid development of renewable energy and electric transportation, energy Storage Technology as one of the key supporting technologies, it has received more and more attention. In the energy storage system, lithium batteries with different powers play different roles. This article will introduce the application of common 5KW, 10KW and 15KW lithium batteries.

I. Application of 5KW lithium battery for energy storage

1. household application: 5KW lithium battery is suitable for energy storage of household photovoltaic power generation system. By connecting with photovoltaic power generation system, 5KW lithium battery for energy storage can store surplus electric energy generated by photovoltaic power generation system in the daytime, and provide household electricity at night or rainy days.
2. Small commercial applications: in some small commercial places, such as small shopping malls, convenience stores, etc., 5KW lithium battery storage can be used for peak and valley filling, helping merchants save electricity costs and improve electricity efficiency.

II. Application of 10KW lithium battery for energy storage

1. industrial application: 10KW lithium battery energy storage can be used for peak and valley filling and standby power supply in the industrial field. In factories and enterprises, power demand often has a certain difference between peaks and valleys. 10KW lithium battery energy storage can help power supply smoothly and reduce peak power consumption costs.
2. Rural power grid transformation: in some remote areas or rural areas, the power supply of the power grid is unstable, and 10KW lithium battery can be used as standby power supply to provide stable power support.

III. Application of 15KW lithium battery for energy storage

1. commercial application: in commercial buildings or large shopping centers and other places, 15KW lithium battery energy storage can be used for peak peaking and standby power supply to help merchants reduce electricity costs and improve electricity efficiency.
2. Micro-grid construction: 15KW energy storage lithium battery can be used as an important component of micro-grid system, providing stable power support, and is suitable for power supply in some remote areas or island areas.

5KW, 10KW, 15KW lithium batteries have different application scenarios in home, commercial and industrial fields, which can meet the energy storage requirements in different scenarios, it provides important support for the development of renewable energy and power system. With the continuous development and maturity of energy storage technology, I believe that lithium battery energy storage will have more extensive application and development space in the future.
