Cost effective Nano home with PV system

This project involved the design and analysis of a cost-effective photovoltaic (PV)-based nanohome system aimed at minimizing power conversion stages and improving energy efficiency. The system was structured to supply two DC loads and one AC load by prioritizing DC appliances, thereby reducing conversion losses. Key components included a boost converter to regulate PV output, a bidirectional buck-boost converter for effective battery charging and discharging, and an H-bridge inverter to supply AC loads. The complete system was modeled and simulated using MATLAB/Simulink to analyze power flow, converter performance, and battery behavior under varying load and generation conditions. Simulation results validated the feasibility of the proposed architecture, demonstrating reliable power management and cost-optimized operation suitable for sustainable and affordable housing applications.
