Today, E3/DC is the market leader in Germany as an inverter manufacturer for grid-connected solar backup power. The three-phase DC technology (TriLINK®) developed by E3/DC and its charging systems for electric vehicles ensure the highest levels of self-sufficiency and savings when used in private and commercial properties – especially in the upper power range. In 2022, E3/DC was named "Brand of the Century" by Florian Langenscheidt for the third time in a row. An independent installer survey conducted by EuPD Research (Bonn) again showed the company a very high recommendation rating in 2022. In April 2019, customer satisfaction was certified by TÜV SÜD. Hager Energy GmbH, certified according to ISO 9001, currently employs around 300 people at its locations in Osnabrück, Göttingen, Lauterhofen, Berlin, and Wetter (Ruhr). The Hager Energy division also includes the location in Saverne (France), with around 60 employees. Lithium storage systems, inverters, wall boxes and other components are developed and produced in Germany.
