The energy storage inverter can connect the Residential Energy Storage System to the independent grid and the transmission and distribution system. It can be used in conjunction with the photovoltaic power generation system to achieve independent power supply and excess power grid.

In the new energy industry, inverters are mainly used in two major areas of photovoltaic and energy storage. The energy storage inverter plays the role of electrical exchanges in the process of battery filling and discharge -DC conversion. Specifically, when the battery is charged, the function of the energy storage inverter is to convert AC power to DC electricity for storage; when the battery is discharged, the function of the energy storage inverter is to convert DC electricity to the use of AC power to use.

The energy storage inverter can connect the Residential Energy Storage System to the independent grid and the transmission and distribution system. It can be used in conjunction with the photovoltaic power generation system to achieve independent power supply and excess power grid. At this stage, the installation of photovoltaic power generation is changing from a centralized to distributed direction. In 2021, the new installation capacity of China's distributed photovoltaic power generation machine exceeded the centralized photovoltaic power plant for the first time. Due to the intermittentity of solar supply, distributed photovoltaic cannot be stable power generation, and the energy storage inverter can store the electricity obtained during the day in the battery and supply at night. It is currently an important solution to solve the stability of distributed photovoltaic power generation supply.

According to the "2023-2027 energy storage inverter industry in -depth market research and investment strategy recommendation report" released by the Xinshi Industry Research Center, it is expected that from 2021-2026, the global rejuvenate compound growth rate is 17. 8 %, showing a rapid rise. Among them, energy storage inverters will become a new driving force for the inverter market. In 2021, the global energy storage inverter demand is 5.89GW, and it is expected to reach 7.12GW in 2022.

From the perspective of principles and technologies, the energy storage inverter is basically the same as the photovoltaic inverter. Photovoltaic inverter manufacturers can successfully enter the energy storage inverter track to increase corporate product lines; and, the energy storage inverter is compared to photovoltaic. The development momentum of the inverter market is stronger, and the energy storage inverter has become an important means for photovoltaic inverter manufacturers to improve competitiveness and profitability. In this context, the scale of the global energy storage inverter industry has expanded rapidly.
