In 1953, German company Kaco manufactured the world's first thyristor inverter, which later went on to produce the first transformerless inverter. . Inverters are a crucial part of any solar power system, responsible for converting the direct current (DC) generated by solar panels into the alternating current (AC) that powers our homes and appliances. In the 1950s, KACO is the world's largest manufacturer of electromechanical choppers and produces the first thyristor inverter. In the 1990s, KACO expands. . Let's delve into the history, concept, and future of inverters. Most household appliances and electronic devices use alternating current (AC), while some power supplies produce direct current (DC). Early electric lighting used large transformers to convert DC to AC. But that required a lot of. . The very first inverters were created using motor-generators as a way of creating AC electricity during World War 2. Redi-line was one of the first and most popular brands at the time. Amazingly, you can still find its inverter generators today! At the time the motor-generator was the only way to. . In 2000, the advent of residential solar was brought about by scientists at Sandia Laboratories in Albuquerque, New Mexico, who invented the modern inverter, called the “non-islanding inverter”.
