Abstract: Design the prototype model of grid tie inverter which includes synchronization, load sharing and reverse metering technique. Main part of the system that control everything is the SPWM based inverter which take the information from grid and independent source of energy and then synchronize the both signals. According to the demand of the load Microcontroller (MCU) makes decision that either the grid feed the load or independent source of energy or both share the load. By sharing the common load with the grid, design an algorithm by which the sharing power with respect to the main grid using droop control technique. This technique minimizes the contribution of the main grid towards the load. Sine Pulse Width Modulation (SPWM) Grid Tie inverter is the most commonly used technique because it is less complicated, more efficient the power loss is minimum and the output sine wave is very close to true sine wave. While in multi-level inverter there is more power loss due to number of components and due to the limitations the output wave is not much like true sine wave. Load sharing by designing buck-boost converter and an adaptive algorithm load sharing can be done automatically according to the demand of load. So, this is more better and efficient then Push buttons
