Technologies for self-determined energy management
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.

Independence for residential and commercial buildings
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. Since the company was founded, over 60,000 home power stations and Quattroporte systems are up and running at our customers’ premises, and are making a contribution towards the environmentally-friendly and cost-saving provision of energy. In our Hager Energy locations in Osnabrück, Wetter an der Ruhr, Lauterhofen, Saverne (France) and Göttingen, we have a workforce of more than 350 employees, who strive to make the vision of independent houses and enterprises, and also solar electric mobility a reality. By storing and using solar energy, our independence from fossil fuel energy increases. Our energy supply can become up to 100 % autonomous. Every year, we produce over 16,000 home power stations, which are manufactured exclusively in Germany, and are subject to the strictest quality controls.

PV-Storage
With the vision of providing freedom and independence through technology, E3/DC has succeeded in offering 100 % independence: if you want it, and whenever you want it. In our image film, you can learn more about the redevelopment of the S10 home power station, and how an electricity storage has to be designed in order to achieve genuine independence.
Our Vision
A self-determined energy supply and sustainable mobility
E3/DC’s development goals are focused on self-sufficient houses and solar-powered electric cars. Because our technological roots are in the automotive sector, we have very high standards in terms of quality and standardisation. Therefore, it stands to reason that we will continue to focus on the big issue of “mobility”. We have already made it possible for our customers to use excess energy to charge their own e-vehicles via the Wallbox, and we continue to work towards increasing the user options, so that energy is always available wherever it is needed.
Determine your own energy supply: the S10 home power station functions simultaneously as an storage for the power produced autonomously, and as a control centre for the distribution of the stored electricity, for various purposes. The result: a genuinely autonomous, flexible and demand-oriented supply – free of charge and up to 100 % self-sufficient.
Our Vision
Self-determined energy supply
Determine your own energy supply: the new era of energy management begins with the option of using solar-generated electricity 24 hours a day. Thus the S10 home power station acts both as an storage for the power produced autonomously and as a control centre for the distribution of stored electricity, for various purposes.
The result: a genuinely autonomous, flexible and needs-oriented supply – free of charge and up to 100 % autonomous.
