Cost-Effective Off-Grid Solar Power System, Integrating MPPT and Smart Battery Management System

The MPPT algorithm described in this research uses the perturb and observe (P&O) approach to maximize power output for a Smart Battery Management System (SBMS). The system produces power that is clean and dependable with an astounding 85% inverter efficiency and a low Total Harmonic Distortion (THD) of less than 2.91 %. It also has a short repayment period 6 years. With two user-specific batteries (Battery 1 and Battery 2) and a central battery (via the SBMS), the design effectively controls reliability and a continuous energy supply. This creative method emphasizes how dedicated the system is to provide cost-effective and environmentally friendly energy solutions. Emphasizing dependability and continuous energy supply, the design incorporates a Smart Battery Management System (SBMS) to efficiently manage two user-specific batteries (Battery 1 and Battery 2) alongside a central battery. Utilizing MPPT controllers for solar panel optimization, surplus energy is seamlessly redirected to the central battery when user batteries are fully charged, ensuring uninterrupted power availability. The emphasis on cost-effectiveness and flexible technology positions this modern off-grid solar power system as a practical and economical solution, addressing energy poverty in rural areas while promoting environmental sustainability through optimized hardware performance.
