One of foremost problems in stand-alone photovoltaic systems consists on the election of a strategy for charge controllers. The charge controllers main function is the accumulation system protection, and this leads to an extension of the batteries lifetime, thus reducing the long term economic cost of the installation. This document describes a Fuzzy Logic based charge controller. In order to show the designed charge controller operation, firstly, a succession of simulations have been carried out to try out the mentioned controller efficiency. Afterwards, the designed charge controller has been used on a real target system to control the charge and discharge processes of a battery in a real stand-alone photovoltaic system, that is installed, on the flat roof of the E.P.S. Jaén of the University of Jaén (Spain). Finally, comparative operation results of the fuzzy charge controller developed are exposed in this document.
