Design of a Compact 600VA Sinusoidal Inverter with Battery Storage System

Due to the increase of renewable energy sources, an efficient inverter system should be designed which can work both in grid-connected and stand-alone mode. This type inverters should be synchronized with the conventional grid system and control the power flow according to the grid voltage and frequency. A 600VA inverter design with battery storage system considering the small weight compared with the available inverter which can be used in both modes has been proposed in this paper. A full bridge DC-DC converter is used for converting the 24V DC input to 380V DC, and SPWM drove H-bridge inverter is used to get the AC output. An LCL filter is used to get the pure sinusoidal output from the SPWM signal. Successful demonstration and the hardware implementation of the overall system has been presented.
