Conversion of existing inverter into solar inverter

The massive use of fossil fuels causes the problem of greenhouse emissions worldwide; this damages the earth's environment seriously. Moreover, the fossil fuels will be exhausted in the future. The use of renewable energies such as solar energy and wind energy has been increased. The sun is a giant powerful energy source; in fact the earth's surface receives too much energy from the sun in one hour to meet its energy requirements for one year. The world energy demand has got high peak in the recent years, as well as the social clamor for environment preservation. Traditional solar-based inverter system is in cascaded, with simple controller and low efficiency. In new solar grid-connected inverter system has reduced power semiconductor switching loss and output stable and synchronized sinusoid current but with higher efficiency. Inverters are in use from very long time, lot of improvement is taking place, as solar is renewable source of energy, it is very beneficial to convert our old existing inverters into solar inverters. This experiment is concentrated on how solar energy is converted into electrical energy in cost effective manner and what are different types of solar inverter systems, their advantages and disadvantages and also their applications have been discussed. The experiment is the study of all the aspects of charge controller with respect to solar inverter to improve overall efficiency of solar system. Experiment also contains study of various phenomenon such as overload, overcharge, deep discharge and depth of discharge.
