Invsetigation of PV inverter MPPT efficiency test platform

In this paper, the test platform of PV inverter MPPT efficiency is researched. The test method of PV inverter MPPT efficiency is analyzed according to evaluation index of PV inverter MPPT efficiency. Based on the MPPT efficiency test method, The PV array simulation should output P-V curve of PV array in different irradiance and different type of PV module. A 500kW PV inverter MPPT efficiency is tested and evaluated by this platform. The test results verify the validity of the test platform which analyzed in this paper.
