Abstract: : This study explains how a smart inverter system is developed and tested to connect solar photovoltaic energy with the main power grid and also support electric vehicle (EV) charging. It focuses on a 100KW three- phase solar inverter that includes smart features like a boost converter to increase the voltage from solar panels and Getting the most power from the sunlight requires use of Maximum Power Point Tracking(MPPT) .The two level inverter changes the solar DC power into AC with Pulse width Modulation(PWM) control also it can be used by the grid and the rectifier change the grid AC power into DC to charge the EV charging stations.The management system manages the electrical potential (voltage), keeps the inverter in synchronization to the grid through Phase- Locked Loop (PLL), and avoids sending unwanted reactive power, making the system clean and efficient. Tests done using MATLAB/Simulink show that the system works well even when sunlight levels change. It keeps the DC voltage stable and delivers the highest possible power.Besides helping the grid; this system can also charge electric vehicles using solar power, either directly or through the grid. This reduces the use of traditional energy sources for charging EVs. Overall, smart grid-connected inverters like this are very important for the shift to renewable energy, providing a clean, smooth, stable connection between solar power, the grid, and electric vehicles
