About Us

Global Leader in Microinverter

Tsun wurde von einer Gruppe junger Menschen gegründet, die seit etwa 10 Jahren in der Solarwechselrichter-Branche tätig sind. Sie sind leidenschaftlich an der Solarindustrie interessiert und waren stets auf der Suche nach technischen Durchbrüchen, die der Branche innovative Veränderungen bringen könnten.

Nach 10 Jahren technischer Weiterentwicklung von String-Wechselrichtern erkannten sie, dass es in diesem Bereich keine Möglichkeit mehr gab, das Produkt auf die nächste Stufe zu bringen. Was wäre also der Durchbruch für Wohn- und Kleingewerbesysteme? Welche bessere Lösung könnten sie in diesem Sektor anbieten?

Sie stellten fest, dass die größten Herausforderungen bei Wohn- und Kleingewerbesystemen das Brandrisiko und das Schattenproblem sind. Aufgrund ihres technischen Designs lassen sich diese beiden Probleme mit einem String-Wechselrichter nicht lösen.

Sie entdeckten, dass nur ein Mikrowechselrichter beide Probleme gleichzeitig lösen kann. Die Frage war jedoch, dass Mikrowechselrichter für alle Systemtypen zu teuer waren.

Ein Hinweis: Wenn die Leistung eines String-Wechselrichters steigt, sinken die Kosten pro Watt erheblich. Könnten sie dieselbe Lösung auch auf Mikrowechselrichter anwenden?

Mit Leidenschaft und Überzeugung gibt es nichts, was nicht erreicht werden kann. Diese jungen Menschen nutzten die Essenz ihrer bisherigen Erfahrungen und beschritten einen Weg, den zuvor niemand zu gehen wagte.

So wurde Tsun gegründet. So entstand auch das weltweit breiteste Leistungsspektrum an Mikrowechselrichtern von 300W bis 6000W. Dies ist auch das Versprechen aller Tsun-Mitarbeiter: Sichere und hocheffiziente Mikrowechselrichterlösungen auf jedes Dach zu bringen und Sicherheit erschwinglich zu machen.

As the founder of TSUN, our vision is to build an innovative company that creates real value for the PV industry, our customers, and the world we live in. Entering the PV field in 2009, I have over a decade of experience, including work with stock-listed enterprises and involvement in large-scale projects such as a 10 GW PV power station. With a solid foundation from Tongji University and advanced studies at FAU Erlangen-Nürnberg, I bring over 15 years of dedication to the solar industry.

With TSUN, we are driven to push the boundaries of photovoltaic technology, making clean energy more safe, powerful, and affordable worldwide.
