The target of this manuscript is to make a review about the Off-grid Photovoltaic Diesel Hybrid Systems (Off-grid Mini Grids) where only AC loads are connected. It will take into consideration the different types (performed through of the DC coupled, AC coupled or hybrid DC-AC coupled configurations), solutions (PV/Diesel and PV/Diesel/Energy Storage) related with the diesel hybridization of those systems and their main elements (power converters). So, it will encompasses an analysis about the current state of the technique of converters implemented in those systems, including the stand-alone inverters, bidirectional, multiport and even the grid-connected inverters implemented in the AC coupled systems. In addition, the standardization in this topic will be analyzed too. (C) 2015 Elsevier Ltd. All rights reserved.
