International audience. Large photovoltaic (PV) plants are being built all over the world, commonly having ratings up to 1 MW and reaching the level of 250 MW. These plants could be an alternative energy source replacing conventional ones and solving the energy dilemma of humanity. However, the associated electronic systems, mainly inverters used for interfacing with the grid, have to solve some problems related to the operation in the electric distribution system. They should be reliable, robust and manageable. This paper presents and discusses the most critical points existing in actual inverters, summarizing, explaining and proposing approaches to solve or mitigate them.
