To design allow cost solar inverter for areas without grid access or for backup power Affordable High efficiency Battery charger stage for night time use
Electricity rate has hiked around 100% in last four years. So we need to focus on alternate option.
CALCULATOR AN EXAMPLE Youve probably seen calculators with solar cells -- devices that never need batteries and, in some cases, dont even have an off button. As long as theres enough light, they seem to work forever. You may also have seen larger solar panels, perhaps on emergency road signs, call boxes, buoys, and even in parking lots to power the lights. That is Photovoltaic energy at work.
Photovoltaic energy is thedirect conversion of light intoelectricity at the atomiclevel. Some materials exhibita property known as thephotoelectric effect thatcauses them to absorbphotons of light and releaseelectrons. When these freeelectrons are captured, anelectric current results thatcan be used as electricity.
This energy generated by the panel, in the form ofdirect current (DC), is transmitted to the inverter. Thejob of the inverter is to convert the DC power the solarpanel has generated to alternating current (AC) that istransmitted on the grid.The inverter converts DC to AC by using two switcheswhich convert the positive only DC power to analternating positive to negative AC power. The inverterwill then step up the voltage from 12 volts to 120volts, which is the voltage used throughout the USelectrical grid. This conversion of voltage is whatallows a 12 volt DC solar polar to be tied into a 120volt AC grid.
