ABSTRACT
This project centers on integrating a solar inverter system into a 9kg LG T9585NDHVH automatic top loader washing machine to reduce operational downtime and enhance profitability, especially in areas with unstable electricity supply. The main goal is to create a washing machine that can seamlessly transition between grid power and solar energy, ensuring continuous operation even during power outages. By utilizing solar power through an inverter, the system not only decreases reliance on traditional electricity but also provides a sustainable and cost-effective energy solution. The design process involved selecting suitable solar panels, inverters, and batteries to meet the washing machine's energy needs while ensuring efficiency and reliability. The first step included a comprehensive modeling and evaluation process to determine the optimal specifications for the inverter system. The project utilized two 300W monocrystalline solar panels, a 1.5 Kva 12v inverter, and a 100ah 12v dry cell battery. Additionally, a 30a PWM charge controller was incorporated to facilitate smooth integration with the solar panels and maximize the system's ability to utilize renewable energy sources. The system's design and component selection can be further refined to better align with the project's specific objectives. For component formation, methodological studies, including flow charts, were used to guide the project’s production, planning, and testing phases. Experimental testing confirmed the system's success in reducing downtime and providing a reliable washing experience, particularly in rural and remote locations. The project demonstrated an average electricity savings rate of 32.76%. These results validate the findings that the solar-powered washing machine has met its intended goals. This innovation offers a practical solution for increasing household appliance resilience against power interruptions while promoting the use of renewable energy.
