REFU Hungary Kft. was established in 2021 as a subsidiary of the German REFU Elektronik GmbH to manufacture products for its own and other OEM partners.
Although initially part of REFU Elektronik, REFU Hungary Kft., now operating as an independent entity, provides full-service electronics contract manufacturing services, including design, prototyping and mass production, at the Prettl campus in Érd. Special attention is given to the development and production of solar inverters and energy storage systems, contributing to the deployment of renewable energy sources.
In addition to its own services, REFU Hungary Kft. also supports the members of PRETTL Ventures and sells the group’s products in Hungary and neighbouring countries.
Our priority is to promote market access for the products and services of our group members, contributing to growth and innovation in the region.
REFU Elektronik Gmbh and REFU Hungary, members of PRETTL Ventures, are committed to making a significant contribution to sustainability and preserving the environment for future generations.In 2020, the group launched the GoZero initiative, a voluntary commitment to climate protection. This project will showcase the company’s path to achieving climate neutrality, focusing on four key areas: energy efficiency, renewable energy, green energy and offsetting measures. REFU is determined and systematic in pursuing these sustainability goals.
At a time when the demand for sustainable practices is becoming increasingly vocal, PRETTL Ventures is committed to shaping a sustainable future through the GoZero initiative. Led by PRETTL Ventures and the GoZero Initiative, we are working hard to minimize our environmental impact and achieve climate-neutral production by 2025.
GoZero strives to promote innovative solutions and sustainable business practices that offer both environmental and economic benefits. REFU Elektronik GmbH and REFU Hungary Kft. play a key role in this initiative as members of PRETTL Ventures. Since the early 2000s, REFU has been a leader in the development of inverters for solar PV systems. Its products, marketed under the REFUsol brand, are recognised worldwide and its inverters have become an integral part of many solar PV systems. The reliability and durability of its products are highly appreciated by customers worldwide.
The integration of GoZero into PRETTL Ventures underlines its commitment to a sustainable future. Its joint efforts will focus on renewable energy, recycling and ethical sourcing to make a significant contribution to the environment. Synergies within the group will enable it to build a world that is valuable for future generations.
Our cooperation under the GoZero initiative covers all areas of PRETTL Ventures and its subsidiaries.
