A grid tie micro inverter is a small, advanced inverter that connects each solar panel directly to the grid. Each system unit operates with only tens of volts of DC voltage and is connected in parallel, which minimizes potential safety hazards. Renesas provides high-performance MCU alongside all. . This design is a digitally-controlled, grid-tied, solar micro inverter with maximum power point tracking (MPPT). In order to harvest the energy out of the PV panel, a Maximum Power Point Tracking (MPPT) algorithm is required. They are safer to install, good for solar systems that encounter shade, and allow for future system expansion.
