The main difference between energy storage inverters and ordinary inverters lies in their functions and application scenarios.
The main function of a regular inverter is to convert DC power into AC power for use in household, office, factory and other electrical equipment. This type of inverter typically has high power, such as in the kilowatt level, and can meet various power needs. The energy storage inverter is a special type of inverter, whose main function is to convert AC power into DC power to store electrical energy. This type of inverter typically has a large storage capacity, such as in the kilowatt hour range, and can store a large amount of electrical energy in a short period of time. They are widely used in situations that require stable power supply, such as hospitals, data centers, industrial parks, etc. Energy storage inverters can also provide backup power in the event of grid failures to ensure the continuity of power supply.  
In addition, energy storage inverters can also stabilize the operation of the power system by adjusting the grid frequency.  
Overall, there are significant differences in functionality and application scenarios between energy storage inverters and ordinary inverters. Ordinary inverters are mainly used to convert DC power into AC power to meet daily power needs; Energy storage inverters are mainly used to convert AC power into DC power to store electrical energy.
