Power electronics from Germany

Engineering expertise meets industrial experience

Where technology is created,
it makes a difference

Anyone who opts for a photovoltaic system is making an investment that is intended to function reliably for many years to come. That is why it is not just what an inverter can do that matters, but also who is behind it, where it is manufactured, and who takes responsibility for it in the long term.

KOSTAL develops and manufactures power electronics in Germany. At our production site in Hagen, we build inverters in line with the quality standards expected of a German industrial company. 

For us, ‘Made in Germany’ is therefore not merely an indication of origin. It is part of our commitment to quality.

From Hagen ‘up onto the roof’

At KOSTAL’s Hagen site, decades of experience in power electronics meet modern industrial manufacturing. This is where the key components of our energy solutions are produced – using defined production processes, quality checks and the expertise of our staff.

For installers and plant operators, this means you are not opting for anonymous technology, but for a product with a traceable origin.

 

Quality is embedded throughout the entire process

Reliability cannot simply be written on a product label. It begins with development, continues through the selection and processing of components, and extends to the tests carried out during and after manufacture. This is how power electronics are created that are designed for long-term use in photovoltaic systems.

Today, an inverter must be capable of far more than simply converting direct current into alternating current. Photovoltaics, battery storage, electric mobility, energy management, heat pumps and the electricity grid are increasingly converging to form a smart energy system.

This requires power electronics, software and a deep understanding of the energy market’s requirements. KOSTAL combines this expertise with the experience of a German industrial company. Technology from Germany – developed for the energy world of today and tomorrow.

 

Designed to meet the requirements that really matter

The German energy market is changing rapidly. Grid requirements, energy management, controllable consumption devices and new marketing models are constantly placing new demands on photovoltaic systems.

For us, therefore, Germany is not simply a sales market. It is our home market. Our products and solutions are continuously developed with the needs of installers, system operators and the energy infrastructure in mind. Close to the market. Close to the trade. Close to the requirements.

‘Made in Germany’ doesn’t end at the factory gates

For us, a product is about more than just its manufacture. After all, the choice of manufacturer often only becomes crucial years later: when a technical issue arises; when an update is needed; when regulatory requirements change; or when support is required.

That is why our products are backed by an infrastructure that takes on long-term responsibility.

  • German service: German-speaking technical support
  • German guarantee: Clear points of contact and standardised processes
  • German contractual terms: Transparent conditions and a tangible contractual partner
  • Software and updates: Continuous maintenance and further development of our systems
  • Academy and training courses: Expertise for those who plan, install and maintain our products

 

An inverter lasts for many years. The manufacturer should too.

A photovoltaic system is designed to last for decades. It is therefore vital to have a partner who not only offers an attractive product today, but who will also be available tomorrow.

KOSTAL stands for long-term industrial expertise, continuous product development and a reliable partnership.

After all, future-proofing also begins with the question of who you entrust your energy supply to.
