Smart Solar PV Charge Controller System for Off Grid Applications

The paper describes the execution of a smart solar PV charge controller that exploits the operational capacity of the Raspberry Pi. Modern solar panel technology, boost and buck converters, battery storage and a DC motor load are all included in the system. The Raspberry Pi serves as the central component, facilitating simple control and information sharing amongst the various components. To optimise energy flow to the battery, a buck converter regulates voltage, a boost converter efficiently extracts power from the solar panel, and advanced algorithms are used in the charge controller. Real-time monitoring of the battery’s level of charge ensures maximum performance and durability by preventing overcharging or deep draining. In addition, the charge controller regulates the power delivered to the DC motor load, providing a stable and consistent power source. By using the intelligence of the Raspberry Pi, the system enhances the efficiency of solar energy collection and utilisation in off-grid scenarios, thereby contributing to sustainable energy solutions.
