Studer Innotec is a Swiss company, working in line with the Swiss culture of innovation, quality and reliability. Our team is fully committed to these values, which are also our promises. And only the one who makes a promise can keep it. Therefore our products are developed, manufactured and tested in our facility in Sion, in the middle of the Alps. Our inverters, inverter/chargers and MPPT solar charge controllers are all made in Switzerland. In fact, the Swiss quality require full control of the development and the manufacturing process until the final testing of every single product before dispatching. This is what  brings the product reliability that we are known for, and proud of.
