With the vigorous development of new energy industry and low-carbon economy

photovoltaic inverters showed explosive growth

and their quality testing was also facing significant pressure.Therefore

it was of great significance to develop and design a reliable detection system for photovoltaic inverters to ensure the safe operation of products.This paper introduced the structure

working principle of photovoltaic inverter and photovoltaic power generation system requirements for the quality of the photovoltaic inverter

and put forward a design of photovoltaic inverter parallel detection system.It was analyzed from the system structure

software and hardware composition

and equipment network mode of the system

and the function reliability of the system was verified through the typical performance test.
