The competence of the SOLARMAX Group is there for you before, during, and after your purchase, and thus offers excellent investment protection. We can answer all questions concerning our products, throughout their working lifetime and regardless of location. Of course, you can also rely on Bavarian quality in our customer service, from advice to warranties.

Important: As a result of insolvency, every sold device of the former Sputnik Engineering AG in Biel / Bienne, lost its claims of warranty and guarantee.



As a matter of course, we will be gladly available, not just during the warranty period, but also afterwards for your needs with words and deeds and offer additional services to optimise your photovoltaic plant and/or your inverters. Constantly, we are optimising our performances and inform you on request by our regular Newsletter. Alternatively, please contact us directly for your personal request.

Simple, uncomplicated and solution-oriented!

Our hotline is available at your convenience for technical questions and problems.
