This paper presents an evaluation of the productivity of photovoltaic generators, using different configurations in charge controllers employed in isolated systems, these controllers being interconnected to form a direct current distribution nanogrid. To support the study, the nanogrid used is presented, which is found installed at the test area of Group for Studies and Development of Energy Alternatives (GEDAE) from Federal University of Pará. Throughout the paper, the main equipments responsible for forming a grid in this type of system is indicated, them being the charge controllers, associated whit energy storage systems and photovoltaic generators. In this context, different configurations form those recommended by manufacturers are adopted, but within acceptable limits, whit the aim of increasing the productivity of photovoltaic generators and reducing capture losses. According to the obtained results , when only one generation and storage system as in operation, an increase in generation productivity and a reduction in losses due to capture were observed; when the nanogrid was analyzed with all systems in operation, whit different configurations, a reduction in losses due to capture was found, but an increase in productivity could not be identfied, mainly due to the exchange of energy present in the nanogrid.
