20 years KOSTAL Solar Electric Shaping the Future Through Experience KOSTAL Solar Electric celebrates its 20th anniversary in 2026. Since its founding in 2006, the company has been developing innovative power electronics for residential and commercial photovoltaic systems. As part of the KOSTAL Group, which has been in existence since 1912, KOSTAL Solar Electric combines decades of industrial experience with the continuous development of intelligent energy solutions.
New requirements, digital networking, and increasing demands for the flexible use of renewable energy shape this evolution. KOSTAL addresses this change with durable product concepts, high manufacturing quality, and development and production in Germany.
“For 20 years, we have been developing power electronics that enable the efficient and intelligent use of renewable energy. In doing so, we combine the experience of the KOSTAL Group with a blend of reliability, quality, and technological innovation—that will remain our path in the future as well,” explains Frank Henn, Managing Director of KOSTAL Solar Electric GmbH.
The history of KOSTAL Solar Electric is defined by product developments that have created new possibilities for planning, installing, and using photovoltaic systems. Key milestones include:
Even in its anniversary year, KOSTAL Solar Electric keeps its focus on the future. With new solutions for residential and commercial applications, the company continues to consistently develop its portfolio.
The HELIVOR AXIS combines inverter and battery storage into a compact energy center for the home. The fully coordinated system solution simplifies planning, installation, and commissioning, seamlessly bringing together the flexible concept of the KOSTAL product family.
The PLENTICORE BI 25 was specifically developed for the requirements of commercial storage applications. Featuring power output up to 25 kVA and multiple battery connections, it enables powerful and flexibly scalable storage solutions.
The second generation of the ENECTOR wallbox can now be integrated more comprehensively into the KOSTAL energy system. Intelligent charging functions allow for the demand-oriented use of self-generated solar energy. An additional MID version equipped with an energy meter supports tracking charged energy quantities—such as for charging a company car at home.
The 20th anniversary is also an occasion for KOSTAL to express its gratitude to the installers, partners, and customers who have accompanied the company on its journey. As part of an anniversary campaign, KOSTAL is launching a major competition with attractive prizes centered around the KOSTAL product world.
With 20 years of experience in the solar industry, development and manufacturing in Germany, and a product portfolio consistently focused on flexibility, safety, and easy installation, KOSTAL remains a reliable partner for installers and plant operators into the future.
Open interfaces, flexibly expandable systems, and intelligent solutions for photovoltaics, storage, and e-mobility create the foundation for an energy supply that delivers today and continues to grow alongside new demands tomorrow.
