Abstract:

This paper briefly introduces the principles and structure of grid-connected solar micro-inverter system. Depending on different input solar power conditions, one novel method is proposed to generate the connection mode between solar panel group and micro-inverter group. Compared with existed technology, the proposed technical solution can not only enlarge the operating voltage range of the grid-connected solar micro-inverter system, but also increase the total conversion efficiency of micro-inverters.
