🚀 Overview

The Intelligent Energy Management System (IEMS) is a smart, ESP32-based solution designed to manage energy flow between solar, battery, and grid power in real-time. It prioritizes energy efficiency, system protection, and autonomous decision-making using IoT capabilities and a modern web dashboard.

Built in response to SIH 2024 Problem Statement PS 1572, IEMS contributes to developing a robust Energy Storage System (ESS) that integrates renewable sources and enhances grid stability.
