The Pioneer Era of REFUsol Inverters

Since its acquisition by the renowned PRETTL Group in 2004, REFU Elektronik has undergone impressive development. Under the umbrella of the PRETTLgroup, the foundation was laid for an era of growth and innovation that continues to this day.

The REFUsol inverters were pioneers of their time. Particularly, the early models set new standards in terms of performance and efficiency, establishing REFU Elektronik as a leader in the solar industry. Through continuous research and development, the company succeeded in creating inverters that were not only reliable and durable but also highly energy-efficient, making them a preferred choice for solar plant operators worldwide.

REFU’s commitment to excellence and innovation has been recognized through numerous awards and accolades. The company received the “High Efficiency Winner” award from Photon Lab from 2007 to 2010 and was recognized as one of the “Top 100 Top Innovators” from 2011 to 2013. Additionally, REFU was honored with the prestigious Red Dot Design Award in 2013 and the Solar + Power Award in 2017.

With nearly 400,000 inverters deployed worldwide, REFU has made a significant contribution to the spread of renewable energy. Particularly in the core markets of Europe and Asia, with nearly 300,000 units in operation, as well as in India, a historically strong and important market for the company, the REFUsol inverters have been widely distributed.

Furthermore, REFU Elektronik has continuously expanded its business fields. The founding of REFUstor GmbH in 2019 marked the company’s entry into the energy storage sector before being sold to PRAMAC in 2022. In the field of electric mobility, REFU Elektronik has also taken a pioneering role. The establishment and spin-off of the department in 2016, together with Bharat Forge as a joint venture under the name REFUdrive GmbH, demonstrates the company’s innovative spirit and pioneering drive.

REFU Elektronik has also made a name for itself through the development of groundbreaking products. As one of the first manufacturers, the company was able to introduce a 100K inverter to the market, further solidifying its position as a technology leader. Through continuous investments in research and development, REFU Elektronik remains at the forefront of the industry and drives innovation forward.

REFU Elektronik can proudly look back on an impressive list of references. Their products have been successfully deployed in numerous projects worldwide, contributing to the advancement of renewable energy and supporting the energy transition. From small solar installations on residential homes to large industrial plants and solar parks, REFU Elektronik has fundamentally changed the way energy is generated and utilized and will continue to play a leading role in the industry.
