Within this framework, REFU Hungary Kft. has become a strategic extension of the group’s manufactur-ing footprint—its role in the EU growing swiftly from a support and prototyping facility into a full-scale production site that now serves as the group’s central hub for contract manufacturing, end-assembly, and logistics. The Hungarian operation focuses particularly on clean-energy systems: solar inverters, hybrid storage solutions, and e-mobility infra-structure, including AC/DC charging sta-tions and wallbox systems.“Our value lies not just in production volume, but in flexibility, traceabil-ity, and engineering support—helping OEM partners scale efficiently into the European market with Made-in-EU reli-ability.” — Gyula Virág, REFU Hungary.What distinguishes the Érd facility is not sheer output alone, but the combina-tion of flexibility, traceability, and engi-neering-aware manufacturing. As REFU Elektronik sharpens its focus on energy-transition technologies, REFU Hungary plays a key role in translating that in-novation into real, manufacturable, and scalable solutions.Milestones: from R&D support to series productionThe initial scope for REFU Hungary was to support R&D and prototyping for in-ternally developed inverter and energy
