This project presents the design and development of an IoT-based solar inverter system with real-time monitoring using ThingSpeak. It aims to enhance the efficiency, reliability, and remote accessibility of solar energy systems by integrating sensors and a microcontroller with Wi-Fi connectivity. The system captures energy through a solar panel, stores it in a battery, and converts DC to AC using an inverter for powering loads. Simultaneously, sensors collect important data like voltage, current, and battery levels, which is transmitted to the ThingSpeak platform via Wi-Fi. This enables users to monitor the system remotely through visual dashboards, ensuring better energy management, early fault detection, and improved system performance. The main controlling device of the project is an Arduino UNO Microcontroller. To achieve this task microcontroller loaded program written in embedded C language.
