25 years of KACO new energy

A Swabian success story

A pioneer right from the start

Every journey begins with a first step. KACO took this step in 1914 when it was founded in Heilbronn by Gustav Bach, Albert Hirth and Gustav Klein. The company concentrates on the manufacture of motor seals, shaft sealing rings and electromechanical choppers, the forerunners of today's inverters. In the 1950s, KACO is the world's largest manufacturer of electromechanical choppers and produces the first thyristor inverter.

We turn passion into power

In the 1990s, KACO expands its developments in photovoltaics. This promising sector generates so much enthusiasm and inventive spirit that in 1998, with Dipl.-Ing. Ralf Hofmann at the helm, a separate limited company is established: KACO Gerätetechnik. The very next year, the company launches the world's first transformerless photovoltaic inverter.

In the 2000s, the company relocates its headquarters to Neckarsulm, changes its name to KACO new energy GmbH and establishes further subsidiaries in Europe as well as in North America, Asia and Africa. Today, the name KACO new energy is one of the best known in the inverter industry worldwide.

Strong and reliable partners like KACO are crucial to our success in PV expansion: on the product side, KACO inverters combine reliable technology with high efficiency. On the process side, the excellent service and short communication channels ensure uncomplicated coordination and enable solutions to be found quickly. We are also proud to be involved in the Solar-Cluster Baden-Württemberg with KACO. Together, we are driving forward the expansion of solar energy in Germany and the state of Baden-Württemberg.

Success comes to those who break new ground. KACO new energy has proven this many times since it was founded. We have been working together for over a decade now. We complement each other wonderfully as a team, as we, ebm-papst, have also been continuously setting global market standards as a technology company since our foundation in 1963. We are confident that we will continue to grow together as strong partners in the future and congratulate KACO new energy on this very special anniversary.

Mark Gartner, Senior Director & Global Lead, SBF Renewable Energies // ebm-papst SEA Pte. Ltd.

20 years ago, photovoltaics was still an "unpleasant appendage" to the grid. Energy suppliers predicted that it would never claim a relevant share of energy generation. Today we know: The opposite is the case. We support the grid significantly with our technologies and inverters. I am incredibly proud to have helped drive this development. I still remember very clearly when I commissioned the first inverter I was involved in developing in the former KACO building in Heilbronn on Kreuzeggerstrasse. I was sitting at the lab bench and then it happened: the disk spun backwards and our PV inverter generated electricity. That was a very impressive moment that I will never forget, and it gave me lasting motivation to continue working on the technology.

KACO new energy is more than just a job for me. I have been working for the company for as long as I can remember. I started there in 1990 as a working student, later became a development engineer and now, as CSO and CTO, I am responsible for sales and the technical areas. We started out in 1999 with a team of twelve, wanting to do something good for humanity and improve the energy supply for the world - long before photovoltaics was a business model. KACO new energy and all its employees embody this passion to this day. It drives us every moment and makes us a good team.

It's incredible how quickly 25 years go by! My wish for the future is that we will continue to enrich the PV market for at least another 25 years and remain true to our focus of offering particular benefits for our customers in the form of innovations, the best technology and outstanding quality. I am sure WE CAN!

Matthias Haag, CSO/CTO, KACO new energy GmbH

I have a very special and, above all, personal connection to KACO, which began long before I started working for the company: My grandfather came to Germany as a guest worker and got employed by KACO. As a result, a large part of my family now lives in Germany. In addition, my wife's uncle was also an employee at KACO as head of the electrical department. And in my role at my previous company, KACO was the first customer I landed. When the PV world experienced a big boom in 2010, I finally moved to KACO new energy and joined the HR department. I am now the company’s CFO and can look back on many valuable human encounters over the last 14 years.

The takeover by Siemens opened a very exciting chapter for everyone involved. We found ourselves in a difficult time and saw the Siemens corporation as a safe haven. A lot of things have changed for the better as a result: For example, we now have flat hierarchies and the teamwork across all departments is extremely cooperative – we stand up for each other. The characters in our team fit together well. That is very important to us as management.

Over the past 25 years, KACO new energy has delivered countless megawatts to customers worldwide, founded various subsidiaries in numerous countries and achieved impressive development. I am proud to be a part of this and wish KACO new energy continued success at every level – from financial and technological aspects to human ones, as well.

George Jakob, CFO, KACO new energy GmbH

25 years is an eternity in the solar industry, especially as the sector is constantly characterized by market fluctuations. Against this background, it is a great achievement that we as a German company have been on the market for so long and will hopefully continue to be so successful for the next 25 years.

Green energy is what moves us all. This is one of the reasons why KACO new energy is so close to my heart. I really enjoy working with the people here. For me, that's the greatest thing at the moment, every day anew.
