SMA Solar Technology (Germany): Founded in 1981, SMA became one of the first major manufacturers of grid-tied inverters. Their work in the 1990s and early 2000s set the standard for residential and commercial inverters, and their inverters remain widely used worldwide. . The first inverters appeared in the early 1900s and were mechanical devices that used rotary converters. These rotary converters were inefficient, bulky, and required regular maintenance, but they were an important first step in converting energy for various uses. Early applications were mainly for. . The history of Fronius' youngest business unit dates back to 1992 when Fronius Solar Energy was founded. Some people credit the invention of the solar cell to French scientist Edmond Becquerel, who determined light could increase electricity generation when. . The very first inverters were created using motor-generators as a way of creating AC electricity during World War 2. David Prince is credited with coining the term “inverter” back in 1925.
