As the core component of the photovoltaic power generation system, the quality of photovoltaic inverter directly determines the quality of photovoltaic power generation, and directly affects the safety and reliability of photovoltaic power generation system access to the grid. A method for the consistency verification of photovoltaic inverters is proposed to evaluate the quality of field inverters and the quality of the sample through the type test. Using RT-LAB semi physical virtual simulator, a set of consistency evaluation platform for photovoltaic inverter is constructed. The principle of this method and the construction of the platform are introduced. At the end, the author conducted a concrete case study.
