ABSTRACT
The development of inverters has been driven by the need to convert direct current
(DC) into alternating current (AC) for various applications, addressing the challenges of
uneven energy distribution globally. This imbalance arises from geographic disparities,
infrastructure limitations, and economic inequalities, impacting access to energy. Measures
like expanding electricity grids, adopting renewable energy sources, and enhancing energy
efficiency are crucial in addressing these issues.
The inverter design in this project incorporates a System-on-Chip (SoC) with a SIM
module for wireless communication. When an SMS is received, the SoC triggers the
microcontroller, activating the driver circuit, which controls the transformer to step up 12V
DC to 220V AC. The performance evaluation includes testing under varying loads,
measuring output voltage, current, and operational duration to ensure reliability and
efficiency.
Results showed that the SMS-based remote-controlled inverter system consistently
met household power demands, ensuring stable energy during outages. Remote control was
tested beyond the inverter’s vicinity, confirming effectiveness. Overloading risks and
performance issues in low sunlight were addressed through load breakers and effective
charge management, which optimized battery charging and voltage regulation. Tests
validated stable output voltage, efficient remote switching, and overall system reliability
under different load conditions.
In conclusion, this project highlights the potential of sine wave inverters as a
sustainable power solution, offering economic, environmental, and social benefits. Future
advancements could explore alternative communication methods, such as IoT protocols or
mobile applications, to enhance user experience and provide a more intuitive remote control
interface, making power management more accessible and efficienT
