Reliable Standalone Solar Battery Charging System Using Arduino Based On Mppt Controller

Résumé: This paper aims to provide a study and a realization of a reliable standalone solar battery charging system, it is the main unit of the independent PV systems, used to manage the power sent from the photovoltaic panel to avoid damaging the battery, this one is a very sensitive device to charging / discharging. For this reason, a special control system (called charge regulator) is placed between the photovoltaic installation and batteries to maintain and optimize the functioning of the energy chain. The studied system consists of a photovoltaic module delivering 10w, and a static dc - dc converter of buck type, controlled by a rectangular signal PWM (pulse width modulation) by varying the duty cycle. the signal is generated by the ARDUINO-UNO board where the maximum power point tracking (MPPT) algorithm named perturb & observee (p & o) is implemented to charge a 12v battery, using the ISIS proteus software to make the virtual simulation of the different parts of the system before proceeding to the practical realization which results are satisfactory
