Abstract: Nowadays the need for the electricity is increased in a great manner, so it is necessary to produce electricity in a large amount using renewable sources. One of the most abundant renewable sources of energy is solar energy. This paper aims in designing the low cost PWM inverter using solar energy which produces a sine wave and is controlled using a microcontroller. The generated sinusoidal wave will be of very less harmonics. The technique on which inverter works is mainly based on the pulse width modulation technique which is generated and controlled by microcontroller. The obtained inverter is tested with different AC loads and is primarily concentrated on low power consuming electronic devices such as routers, chargers, bulbs etc. The suggested model of the inverter is of low cost and it’s a feasible design. The design is simulated using Proteus software to get the desired output results which is verified practically.
