In this paper, a small photovoltaic power generation system based on micro-inverter is introduced. In order to overcome the shortcomings of stand-alone mode and grid-connected mode, an operating method is presented. The system is parallel with the single-phase grid to enable grid-connected operation without power injection. Simulation results show that the system could steadily work in two different modes, improve the efficiency of power generation, and reduce the impact to power grid.
