The site took on full industrialization and series production of two OEM co-developed energy solutions—one in residential storage, the other in C&I-sized power conversion. These projects became an inflection point, proving the site’s ability to manage high-complexity builds while remaining responsive to customer timelines.Partnering with Innovators - Not Just Industry GiantsWhile REFU Hungary serves mid and large size OEMs, the site was built with startups and emerging technologies in mind.“We know that bringing a disruptive energy product to market isn’t just about scaling—it’s about doing it without losing speed, agility, or own-ership. That’s why we don’t think like a contract manufacturer. We think like a scale-up partner.”The facility supports low-to-mid volume production, fast prototyping, and itera-tive development cycles, allowing tech-nology innovators to move from proof-of-concept to industrialization without costly transitions or loss of control.In select cases, REFU Hungary is also open to joint development or co-invest-ment models—working side-by-side with visionary teams to bring novel en-ergy, storage, or mobility technologies to market under EU-compliant manu-facturing standards.Most recently, the company concluded a strategic agreement with a leading Asia-based OEM that will see REFU Hun-gary begin local assembly of battery cells for the European market. This step underscores the breadth of technical expertise the team has developed in a short time and reflects the broader shift toward regionalization of critical energy-tech manufacturing within the EU. Operationally, the Érd site now man-ages final assembly, software flashing, testing, and outbound logistics on-site, with full process traceability via ELAM and SAP-integrated MES systems. Core platform design and certification remain centralized in Germany, with seamless cross-site collaboration during industri-alization and ramp-up.Manufacturing model and embedded testingThe facility in Érd is deliberately config-ured for high-mix, mid-to-high-volume assembly. A modular line setup enables rapid scaling based on customer de-mand, while configurable workstations allow teams to accommodate frequent new-product introductions without dis-rupting throughput. The manufactur-ing environment spans multiple dedi-cated lines for power-electronics and energy-storage products, covering both wall-mounted devices and larger cabinet systems.Validation is deeply embedded in the process: firmware flashing, burn-in, and end-of-line functional testing are per-formed on every unit to safeguard field reliability. This test-heavy approach is complemented by digital traceability tools that track each assembly step in real time, supporting continuous im-
