Proteus Based Simulation of PV Inverter for Rural Electrical Service

In many remote or underdeveloped areas, direct access to an electric grid is impossible and a photovoltaic inverter system would make life much simpler and more convenient. With this in mind, this paper aims to design, and simulate PV inverter in proteus professional software. This inverter system could be used as backup power during outages, battery charging, or for typical household applications for rural especially. The principle is to adapt the output voltage of the solar module to the battery by using the technique of pulse width modulation (PWM). The sinusoidal pulse width modulated (PWM) waveform is generated from inverter in laboratory by 16 bit microprocessor through program developed using a novel technique of direct modulation strategy .The key features of the system are a true 50Hz, 230Vsinusoidal voltage output, a wide input range, and a power output of up to 350 watts. The overall goal is to design this system while minimizing component costs.. In addition, inverters in the lower price range typically lack most of the features. solar home lighting systems mostly comprises of solar panel, solar charger, battery & a inverter, The main motivation of this paper or the uniqueness of this project is to combine both the solar charger as well as inverter together to ATMEGA 32 RISC based which works up to 16MIBS which reduces the cost as well as the system becomes compact.
