KOSTAL Solar Electric: Quality and innovation by tradition

As a provider of solutions for smart power generation and usage, we work closely with various partners, including those from the Smart Home sector, but also with our customers to enable you to source environmentally friendly, clean energy from your own roof.

We develop and produce our innovative solutions for the energy of the future in Germany so we can offer our customers the very highest quality standards. We benefit from the experience that the KOSTAL Group has gathered from supplying the automotive trade for over 100 years.

True to our "Smart connections." brand promise, which is based on a real spirit of partnership, we support you along the way and share information with you extensively; see, for example, our service area FAQs, designed to make our inverters easier to install, operate and use.

Free product training sessions at various locations in Germany, Italy, Spain, Greece and France improve your specialist knowledge of how to install and set up our products.
