Smart Power Source Management Automatic Selection of Optimal Energy Source (Solar, Grid, Inverter) for Sustainable Efficiency

Authors- Himanshu Ramanlal Patel

Abstract-This paper presents a smart power source management system that automatically selects the optimal energy source among solar power, grid supply, and an inverter to ensure uninterrupted power delivery with sustainable efficiency. The system is designed primarily for industrial applications where both three-phase and single-phase power are required. Using logic gates (NAND, AND, NOT), the system prioritizes power sources based on availability. Solar power is given the highest priority, followed by grid power, and finally the inverter in case of failure of the other sources. The circuit ensures seamless switching between sources using relays and includes voltage and frequency protection features to maintain stable output. This system effectively minimizes power interruptions, reduces energy costs, and enhances overall efficiency, making it suitable for both commercial and domestic applications. Future advancements may incorporate renewable sources such as wind power for further sustainability.
