Abstract:
Solar inverter is a device that sits behind PV panel and converts the DC output of Solar Panel to 220V AC. The DC power from the solar panel is converted directly to a rectified AC signal. This conversion is done by an interleaved fly back converter. A Full-Bridge (unfolding) converter, switched at 25k Hz line frequency, controls the direction of power flow to the grid. This micro inverter has been designed to connect to any PV module having a power rating of approximately 1000 watts.
The Solar Micro inverter Design is controlled by a single micro-controller device. Micro-controller is the heart of the Solar Micro inverter and controls all critical operations of the system. The functions of the controller are broadly classified as : Protection Measures, Maximum Power Point Tracking (MPPT), Sine wave Generation, Boost Converter etc.
