ABSTRACT
Growing energy consumption worldwide, combined with the serious environmental damage caused by fossil fuel dependency, has pushed researchers and engineers to look for cleaner, more sustainable alternatives. Among these, solar-powered charging infrastructure has shown real promiseespecially for places that cannot rely on centralized grid systems. This paper introduces the SOLGRID Charger, a battery charging station powered entirely by solar energy and equipped with real-time energy monitoring.At its core, the system captures sunlight using photovoltaic (PV) panels, converts it into usable electrical energy, and stores it in lithium-ion battery units for charging electronic devices and electric vehicles. To get the most out of available sunlight under changing weather conditions, the system uses Maximum Power Point Tracking (MPPT) technology. A Battery Management System (BMS) handles safe charging and discharging cycles, while IoT-enabled sensors keep track of energy generation, storage levels, and consumption all in real-time.Sensor data is processed through a microcontroller and pushed to a web or mobile dashboard, giving both users and administrators clear visibility into system performance at any moment. The SOLGRID Charger was designed keeping in mind practical deployment scenarios remote rural areas with no grid access, smart city infrastructure, emergency backup power, and sustainable EV charging networks.What makes this system different from existing solar chargers is the tight integration of intelligent monitoring with the charging hardware itself, rather than treating them as separate components. The result is a system that not only generates and stores clean energy but actively helps users understand and optimize how that energy is being used.
