This project focuses on the development of a 5kVA, 48V hybrid solar inverter system aimed at providing a reliable and sustainable energy solution for domestic and small-scale applications. The system integrates solar photovoltaic (PV) energy with utility grid supply to ensure an uninterrupted power source, with solar energy serving as the primary supply and the grid as backup. A hybrid charging approach was adopted to maintain adequate battery capacity during periods of low solar irradiation. The inverter was designed to deliver a stable output suitable for powering common household and office appliances, while incorporating essential protection features to enhance system safety, efficiency, and reliability. Performance evaluation showed that the inverter provided consistent output with smooth changeover between power sources and improved energy efficiency. The project demonstrates a cost-effective and environmentally friendly alternative to fuel-powered backup systems, reducing, dependence on the national grid and promoting cleaner energy usage.
