The main purposed of this paper is to develop a performance analysis setup for a micro inverter under the real working conditions. It allows observing overall system efficiency of the micro inverter including real -time MPPT. It is designed to be able to measure a micro inverter which can support reactive power to the grid. The results are compared with the results of the reference researches. Also, an energy meter is designed in order to measure the input and output values of the micro inverter. An Arduino-based controller is preferred for this study.
