A Smart Maximum Power Point Tracker Solar Charge Controller

This paper presents an innovative Solar Charge Controller with Maximum Power Point Tracking (MPPT) capabilities, leveraging Arduino integration and a combination of active and passive electronic components. The core principle of MPPT revolves around optimizing energy conversion processes. By employing MPPT Charging Technology, excess voltage is adeptly converted into current, significantly enhancing overall charging efficiency. The development of this system involves complex tasks, including the design of a schematic and printed circuit board (PCB), as well as the creation of Arduino code for visualizing charging parameters on a 20x4 LCD screen. These tasks demand specialized skills in both hardware and software design. Notably, this design has been tailored for efficiently charging a widely used 12V lead-acid battery using a 50W solar panel as the primary energy source.
