Abstract

The development of a microcontroller-based pure sine wave inverter for solar energy harvesting primarily focuses to meet the demand for efficient and reliable energy conversion in renewable energy systems. This project aims to develop and construct a pure sine wave inverter utilising a microcontroller that transforms DC current from solar panels into AC power suitable for residential use. The inverter is built with two single-phase H-bridge inverter circuit with present-day Pulse Width Modulation (PWM) technologies, namely Sinusoidal PWM (SPWM), to lower harmonic distortion in the waveform and increase the quality of the electricity. Passive filters have been implemented to the circuit design to enhance the output waveform purity. The project met its goal of developing a cost-effective, efficient, and dependable inverter system capable of delivering high-quality AC output. The findings show that this technology has tremendous potential for use in household and commercial solar energy systems, contributing to sustainable energy solutions and lowering reliance on nonrenewable energy sources. Future development will concentrate on increasing the system's scalability, incorporating smart grid capabilities, and investigating commercialization prospects to fulfil the growing need for renewable energy technology.
