Abstract
The efficient management of solar energy requires controllers capable of maximizing the power extracted from photovoltaic panels while ensuring optimum battery protection. This article presents the results of the design, realization and experimentation of a solar controller integrating a Maximum Power Point Tracking (MPPT) technique. This regulator is based on a Buck-Boost DC-DC converter with the SEPIC (Single Ended Primary Inductor Converter) configuration, designed to lower and raise voltage as required, to ensure efficient charging. To evaluate the effectiveness of the design, the regulator’s performance was analyzed by implementing a prototype, and experimental tests show that the system works well.
