Nowadays, the dominating type of photovoltaic application is the grid connecting photovoltaic system producing the clean power for supporting the electricity grid from year 2000 to 2010, the percentages of gird connected in the reporting countries are from about 55% to 95. A stand-alone power system (saps or sps), also known as remote area power supply (raps), is an off-the-grid electricity system for locations that are not fitted with an electricity distribution system. The control structure of the grid-connected pv system is composed of two structures control : 1 the mppt control, the main property is to extract the maximum power from the pv generator 2 the inverter control, which have the main goal. Grid connected photovoltaic (pv) systems that are connected to the distribution level, particularly with mw capacity, are increasing at an aggressive rate, in order to meet the energy demand. The purpose of this work is on analyzing large, grid connected with three-phase inverter system, which presents the three-phases grid-connected inverter designed for a 800w photovoltaic system.
