FENECON primarily uses lithium iron phosphate (LFP) batteries for residential systems and integrates new, obsolete, and second-life EV traction batteries for commercial, industrial, and grid-scale solutions. Its modular design enables scalable capacity and multi-supplier battery integration. Central to its technology is the FEMS energy management system built on OpenEMS, providing intelligent charging/discharging control, sector coupling, grid services, and over-the-air updates.
FENECON offers modular, scalable energy storage solutions for residential, commercial, and industrial use, including its OpenEMS-based FEMS smart energy management system. Notable products include the FENECON Industrial L system for industrial energy optimization and market participation, capable of integrating complete obsolete EV battery modules without disassembly.
In 2025, FENECON and The Mobility House Energy are commissioning a 48 MWh battery storage facility in Grevesmühlen, Germany, using unused EV traction batteries. Previous deployments include large-scale containerized installations in Germany and the USA incorporating surplus automotive batteries. The company also collaborated with VOSS on the FENECON Industrial L system.
FENECON has received equity investment from BayBG and conducted private placement rounds. In 2025, the company secured a €40M syndicated loan led by UniCredit Bank alongside Commerzbank, Norddeutsche Landesbank, DZ Bank, and Sparkasse Deggendorf.
