REFU Elektronik - Pioneer of frequency converters

Setting new standards with sustainable solutions - this is not only our philosophy, but also the idea to which we have committed ourselves for the future.

In more than 50 years of successful development, we have continuously expanded our expertise in the field of power electronics and are now the leading supplier of power electronics with frequency inverters, solar inverters and energy storage systems in our ever growing portfolio.

We develop and integrate synergistic components for stationary energy solutions and thus offer a common platform for the 'energy revolution' with regard to power electronic devices and systems in all applications. We bundle our competencies in the areas of high-performance electronics and battery storage systems in order to develop economical, efficient and environmentally conscious solutions. The key to our success lies in our ability to combine the expertise in controllable power electronics with customer-specific designs and production.

Our product portfolio can be divided into two areas.


REFUsol - we convert.

We were there when solar energy was still in its infancy over 20 years ago and continue to develop state of the art solutions as the industry matures. We develop highly efficient solutions for medium and large sized PV systems and offer everything you need right from the planning software, string inverters, complete solutions with transformers and monitoring portals as well all from a single source.


REFUenergy - we store.

At REFUenergy we use our competence and experience in the field of power electronics and combine inverters for battery applications with energy management systems to make energy accessible to everyone. Our application areas range from commercial storage solutions for optimizing self consumption to power supply network stabilization to peak-shaving applications and even to diesel-battery hybrid systems. Life needs energy - in an economically efficient and ecologically conscious way and we have the right solution for you.
