Good technique is important.
Being able to get hold of someone when it really matters, too.
A product is only as good
as the service behind it.
A photovoltaic system serves its operators for many years. During this time, questions may arise – during the planning stage, during installation, during commissioning, when expanding the system, or at any point whilst it is in operation. That is when a manufacturer’s true worth becomes apparent.
That is why KOSTAL offers more than just energy technology. Behind our products are people who know and understand our solutions and support our partners over the long term. Personal. Competent. Approachable.
Service from Germany
Anyone who installs photovoltaic systems on a daily basis doesn’t need an anonymous helpline somewhere in the world when it really matters. They need someone who knows the product.
Our technical support team is on hand to help with any queries regarding KOSTAL products and systems – with German-speaking staff and technical expertise.
From commissioning to troubleshooting, and from inverters to networked energy systems. Technical support right where our products are used.
People make the service
Digital processes help to organise service efficiently. But ultimately, behind every process there is a specific system, an installer on site or a system operator with a question.
That’s why we combine digital service offerings with personal technical expertise. Because sometimes a piece of information is all it takes. And sometimes you need someone who understands exactly what’s happening on site. Technology can be complex. Getting support shouldn’t be.
From individual products to the entire energy system
Photovoltaic systems are becoming more complex. Inverters, battery storage, wall boxes, energy management systems, heat pumps, backup solutions and other components must all work together. This also changes the nature of the enquiries made to technical support.
It is no longer just a question of whether a single device is working. It is about whether an entire system has been correctly planned, installed, configured and operated. KOSTAL therefore increasingly views service as system support.
Knowledge before questions arise
Sometimes the best service scenario is the one that never arises in the first place. That is why, for us, technical support begins even before installation. At the KOSTAL Academy, our trainers impart knowledge on all aspects of planning, installation, commissioning and the use of our products and solutions. Practical and tailored to those who work with our technology on a daily basis.
Understand. Install. Use safely.
Service isn’t just a one-way street. The experiences of installers and system operators provide valuable insights into how products are used in everyday life, what questions arise and where solutions can be made even simpler.
This knowledge can be fed back into product management, development, documentation and training. Because for us, being close to the market also means listening.
