HagerEnergy GmbH

The origins of E3/DC lie in the development of energy storage systems for the automotive industry. The E3 automobile is transformed into a mobile storage by the charging, discharging and driving technology developed by the company, Wilhelm Karmann. In 2010, E3/DC, as a spin-off of Wilhelm Karmann GmbH Osnabrück, developed into a manufacturer of inverters. The goal of E3/DC is to achieve sustainable new standards for a household energy supply that offers maximum performance and quality. The well-engineered technologies that originate from the automotive industry are used to make renewable energy available, not only in the area of mobility, but also in other areas of daily life. The company name E3/DC is derived from an acronym of the German words, “einsparend, erneuerbar, effektiv” (saving, renewable, effective), hence E3, and DC or direct current.
