Solar inverters form a major and an essential component of the rooftop solar system. The solar inverters have today evolved from being more than mere boxes, to become more smart and intelligent. The main function of an inverter is to convert direct current into alternating current that help in running the appliances in our homes.
Generally string inverters are more commonly used for rooftop solar, since any default in one string of solar arrays will not effect the entire functioning of the system. The fault can be solved at the string level itself. When using central inverter, the AC is converted into DC at a central level, common to the entire system. Residential rooftops generally cannot support central inverters. Microinverters are the best option for residential solar and is also prevalent in the western parts of the globe. They are more intelligent and smart, but are costlier. Solaredge and Enphase Solar are the largest players in this segment. However they are not commonly seen in India.
