Energy storage systems for the automotive industry

The development of energy storage systems for the automotive industry is the origin of E3/DC.
Vehicle to grid technology was founded by E3/DC in 2010 using complete vehicles from Volkswagen.

 

Technologies for self defined Home Energy Management

The E3/DC GmbH is an inverter manufacturer and was a spinoff of Wilhelm Karmann GmbH from Osnabrück. The vision of E3/DC are sustainable new energy standards for domestic homes with maximum performance and quality. The established technologies, coming from automotive electronics, provide renewable energies in the context of mobility, but also for other areas within the daily life. The name E3/DC is a connection of our mission: E3 (saving/einsparend, renewable/erneuerbar, effective/effektiv) and DC (direct current).

Milestones and awards for the power plants by E3/DC

Proven quality of E3/DC

E3/DC has grown a network of >1.000 certified installers and nearly 9.000 installed storage systems in Germany (since 2012). They provide a sustainable quality and a regional coverage. More than 70 employees in three locations (Osnabrück, Wetter, Göttingen) are subject to rigorous quality and state of the art inverter control. The over 4.000 annually produced systems in Germany are in accordance with the ISO 9001 standards.

Shape your future

The development of E3/DC systems made an important contribution to the sustainable use of resources: Due to the storage and the use of solar energy itself provides maximum decentral and CO2 neutral independence from fossil fuels. This own power supply technology can bring you up to 100% renewable personal footprint. Our products offer innovative, pragmatic and reliable solutions and maximum flexibility in the future, by using state of the art connectivity and hardware interfaces – in mobility, heat technology and electrical home appliances.

Our vision

100% sustainable mobility

The core vision of E3/DC is the decentralized energy production within your house by using solar and CHP (Co-Generation) in order to achieve more production than consumption. By using electrical storage this production can cover a 24h power demand, day and night, day by day.

Our technological roots are from the automotive sector. Therefore, we always keep the topic "electric mobility" in mind and as an interface of our products. Our products can charge cars using self-produced energy. Our vision is to completely substitute the public grid and to make customers physically independent from grid and external supplies. 

Energy self-determined

You decide about your energy profile: The first step is solar generated power, using electrical storage and premium inverter technology. The result: real-grid independence (as an option), 70-100% reduction of electrical power from the grid, electric driving and electric heating.
