The selection of photovoltaic grid-connected inverters plays a vital role in the feasibility study of solar photovoltaic systems. It is directly related to the solar energy utilization rate of solar photovoltaic systems and the normal operation of solar photovoltaic power generation systems. This paper combines the author's actual work experience, from the introduction of the working principle of the inverter, discusses in detail several important factors that should be considered in the selection of photovoltaic grid-connected inverters. Finally, through actual engineering examples, it has reached the full use of solar energy resources and improved solar photovoltaics. The purpose of system stability.
