Champions in the name of progress
Every journey begins with a first step. KACO takes this step back in 1914 when the company is founded in Heilbronn by Gustav Bach, Albert Hirth and Gustav Klein. The company focuses on the production of engine seals, shaft seal rings and electro-mechanical choppers, the precursors of today's inverters. In the 1950s, KACO is the world's largest manufacturer of electromechanical choppers and produces the first thyristor inverter.
In the 1990s, KACO expands its developments in the photovoltaics field. This promising sector creates so much enthusiasm and innovative spirit that in 1998 a separate company is formed with Dipl.-Ing. Ralf Hofmann at the helm: KACO Gerätetechnik GmbH. By the following year the company has already launched onto the market the world's first transformerless solar PV inverter.
In the 2000s, the company relocates its headquarters to Neckarsulm, changes its name to KACO new energy GmbH and founds further subsidiaries in Europe as well as in North America, Asia and Africa. Today, the name KACO new energy is worldwide among the best known in the inverter industry. It is a Swabian success story!
