In this paper, a new technique for the optimal design of the power section and output filter of a full-bridge, grid-connected PV inverter, is proposed. The objective function which is minimized during the Genetic Algorithm-based optimization procedure is the PV inverter Levelized Cost Of the Electricity generated (LCOE). The proposed method has been applied for the optimal design of PV inverters installed at various sites in Europe. The simulation results indicate that the optimal values of the PV inverter design variables depend on the PV inverter specifications, the technical and economic characteristics of the components used to build the PV inverter and the meteorological conditions prevailing at the installation area.http://creativecommons.org/licenses/by/4.0/1-1014th European Conference on Power Electronics and Applications Koutroulis Eftychios Κουτρουλης Ευτυχιος Blaabjerg,F Institute of Electrical and Electronics Engineers Photovoltaic energy systems Photovoltaic facilities Photovoltaic power plants Photovoltaic solar generating plants Power plants, Photovoltaic Power systems, Photovoltaic photovoltaic power systems photovoltaic energy systems photovoltaic facilities photovoltaic power plants photovoltaic solar generating plants power plants photovoltaic power systems photovoltaic
