E3/DC is bringing its "3-fach Energie" concept to ees Europe 2026 in Munich, centred on year-round energy and cost optimisation for fully electric buildings. Stationary storage, the company argues, has long since passed the experimental stage, but monetising flexibility still depends on digital infrastructure that Germany has been slow to build. "Storage of every size brings valuable flexibility to the energy market, but it also needs to be able to monetise that flexibility," says CEO Dr Andreas Piepenbrink. "That is why grid digitalisation matters so much, and why many countries are considerably further along than Germany."
Intersolar Forum 2026: integration and sector coupling in focus
The 3-fach Energie concept addresses this directly. It combines self-generated electricity, cost-optimised grid supply and bidirectional charging into a single managed system, with E3/DC's AI 360° software providing the intelligence. All E3/DC home power stations, regardless of age or model, can run the software without subscription costs, coordinating heat pumps, storage capacity and vehicle batteries across both self-consumption and dynamic tariff applications.
The centrepiece of the stand is the new edsn bidirectional DC wallbox, developed entirely in-house and a finalist for the Smarter E Award. Compatible with all existing and new E3/DC home power stations, it integrates electric vehicles as active participants in building energy supply, using vehicle batteries not just as flexible loads but as additional storage. "Customers receive a fully coordinated, future-proof energy system including permanently free software updates," says Thomas Steinacker, Director Sales at E3/DC.
Markus Elsässer: "The solutions are ready"
Beyond the residential market, E3/DC is also showcasing the qntm, a new C&I storage system scalable for commercial and industrial applications. The system supports self-consumption from large PV installations, dynamic market participation, peak shaving and front-of-the-meter arbitrage trading, with AI 360° managing individual dispatch schedules.
E3/DC is additionally developing an energy sharing model with partners that goes beyond the current legislative framework, using real-time measurement and digital networking across distribution grid balancing areas to enable transparent monitoring and virtual billing through a two-tier tariff structure.
