This paper presents the design of a solar charge controller with the Maximum Power Point Tracking (MPPT). The proposed design uses a microcon-troller (Arduino Nano) which is able to acquire the current and voltage measurements , of the panels and the battery and to apply a certain algorithm which allows to deduce the PWM cycle that will power the converter DC-DC (buck converter) to control the charge and discharge of the battery. The system incorporates a WiFi module for data acquisition and can be used to study the state of the battery and help for maintenance. The results obtained from the implemented on hardware demonstrate the change of the duty cycle with the change in load and thus mean the variation of the buck converter output voltage and current controlled by the algorithm of charge.
