This thesis presents an evaluation of photovoltaics generators productivity, using different configurations charge controllers used in isolated system, which them are interconnected and constituted a distribution nanogrid in direct current. To support the research, there is a contextualization of the microgrids uses and the presentation of the nanogrid employed, which it is installed in the test area of Group of Studies and Development of Energy Alternatives (GEDAE) of Federal University of Pará. Throughout the thesis, the main equipments responsible for the formation of this network are indicated, as the charge controllers, associated with energy storage systems and photovoltaic generators. Different configurations from those recommended by the manufacturers are adopted, but within acceptable limits, in order to increase the productivity of photovoltaic generators and reduce losses. According to the results, when only one generation and storage system were in operation, it was observed an increase in generation productivity and a decrease in losses; when the nanogrid with all systems in operation was analyzed, with different configurations, it was observed a reduction of losses per capture, but the increase of productivity did not appear in the analysis because of exchange of energy presents in the nanogrid
