In this situation, the inverter is coupled with a battery storage system in order to ensure a consistent energy supply. Grid-connected inverters, on the other hand, are able to synchronize with the electrical grid to which they are connected because, in this case, voltage and frequency are "imposed" by the main grid.
Photovoltaic energy storage inverters cover single/three-phase, high/low voltage products, and battery systems can be divided into high-voltage and low-voltage batteries according to voltage

Both energy storage converters and PV inverters aim to achieve AC/DC conversion. However, the energy storage converter operates primarily from the battery side, whereas the PV inverter focuses on the solar panel side and integrates with the battery and grid. Their presence spans across photovoltaic and storage systems, smart microgrids, and
To put it another way, the photovoltaic inverter in the energy storage system not only focuses on the conversion of electrical energy but is also committed to the storage and dispatch of electrical energy to optimize the operation of the entire energy system. DC voltage matching: Each inverter has a nominal voltage, such as 12V-360V, etc
