We turn passion into power

KACO began manufacturing sine inverters more than 60 years ago. The product portfolio offered by KACO today is being used around the globe for rail vehicle and photovoltaic applications.  KACO new energy begins in 2010 as the world's second largest manufacturer of photovoltaic inverters.  With over 3 GW of inverters in operation worldwide KACO is a trusted and reliable partner for photovoltaic systems across the globe.


Photovoltaics - Our Commitment

The sun won’t send us an electricity bill. It provides us with free energy while the fossil fuels we burn for energy cause political conflicts, environmental degradation and are subject to volatile price spikes. The sun will remain readily available for as long as there are people around to harness its energy. It is our commitment to design devices and systems that yield maximum outputs from solar energy. One of our goals at KACO is to preserve our planet’s natural environment as best we can for the generations to come.

Our Philosophy

For over 60 years KACO inverters have been setting the standard for photovoltaic system solutions and customized power supplies. Known in Europe for our high reliability and maximum efficiency, the world's second largest PV inverter manufacturer has now developed a second series of inverters for the US market. Adherence to the highest technical standards is how we ensure our technological leadership.  Read more here about the blueplanet 02xi series inverter for residential and commercial applications or click here to read more on the KACO central inverter.

We have established ourselves in the market of customized power supplies and photovoltaic system solutions as one of the most technologically innovative and reliable companies around. Our strength and competitive advantage lies in our customer-orientated business practices and of power-electronic development specifically designed for our customers.

Quality Management

Another important component that defines KACO’s high standard is our Quality Management System, which defines procedures, organization and process cycles. Our high performance is maintained and continuously enhanced by this extensive, cross-divisional system, which is adapted to changing requirements.

It is the task and obligation of all KACO new energy, Inc. employees to actively take part in our stringent Quality Management System, to follow the defined processes appropriately, and to contribute to continuous improvement.

Innovation through research

As early as in 1999, KACO new energy launched one of the first series-manufactured inverters without a transformer. This made KACO new energy a pioneer in the field of transformerless inverter technology, which yields higher degrees of efficiency. Another example of the company’s innovative power is the early introduction of three-phase monitoring. This method ensures multiple measurements, thus preventing unnecessary inverter disconnection from the grid.

Investments in research and development are key requirements for KACO new energy to maintain this position. Therefore, KACO new energy has established designated research teams in Kassel, Germany, and Neckarsulm for the further development of inverters up to a power class of 100 kW, as well as a team in Seongnam in South Korea for the development of solar inverters of higher power classes.

Committed to mankind

KACO new energy wants to allow the less privileged people in this world to share the company’s success. We are engaged in different projects aimed at people – directly and personally. We do this because we are of the conviction that it is a human imperative. If we are all linked by a sense of mutual responsibility for one another, then we will make life on this planet richer and more liveable. First and foremost for those among us who are blamelessly trapped in living situations that they often cannot overcome with their own strength.


A few of the organisations and projects that we support:

  • “Target” – Organisation led by Rüdiger Nehberg that seeks to stop female genital mutilation
  • “Große Hilfe für kleine Helden” (Big Help for Little Heroes) – paediatric clinic foundation in Heilbronn, Germany
  • “Peter Maffay Stiftung” (Peter Maffay Foundation) – assistance for traumatised children from around the world


KACO new energy is also committed to engaging in political work that furthers the use of photovoltaics. The company invites politicians for regular plant tours and to exchange views. The Senior Management takes part in panel forums and engages in public political discussions.


KACO new energy’s company culture is a very special one. All employees participate in the company’s profit. The company offers free organic food in winter and free soft drinks in summer. Regular foot-races take place, in which company members train for marathon runs. In addition, all employees are invited to work out in the in-house gym for free.
