Customer service and support from KOSTAL: good advice all round

Anyone purchasing a solar system expects good quality and performance. Together with your installer, KOSTAL customer service will make sure that you're happy.

KOSTAL service – guaranteed. Tailor-made. Satisfying

KOSTAL offers efficient training programmes and comprehensive support to our specialist tradespeople, and you benefit from that! Each of our KOSTAL inverters is a quality product manufactured within the KOSTAL Group and is subject to the same quality standards as, for example, our products for the automotive industry. But it's not only our products that are top quality, but our service too, where our focus is always on ensuring that you, the customer, is satisfied.

If you operate your own system, we recommend contacting your specialist installer as a first point of call if you have any questions. If you're looking for a new installer, please use our installer search.
