This paper introduces different methods for testing photovoltaic grid-connected inverter performance index and analyzes the advantages and disadvantages of several kinds of photovoltaic grid-connected inverter testing systems.Based on photovoltaic inverter technical requirements and performance index,a detection system for photovoltaic grid-connected inverters is designed.The system controlled by computers can control all the detection units via GPIB and RS485.DC programmable power supply is used to simulate the direct current simulated via photovoltaic battery array,whereas AC programmable power supply is applied to simulate the power grid.The experimental results show that the test system can automatically achieve the detection of the PV inverter,with reasonable structures,high accuracy and high reliability.
