Power Conversion Units for multi-megawatt electrolyzer applications
Our aim is to drive green hydrogen at scale through our cutting-edge technology, strategic partnerships with electrolyzer companies, and efficient, agile project execution across the entire value chain. The SMA Power Conversion Units (PCUs) are a proven solution for the power supply of electrolyzers in more than 80 hydrogen projects worldwide. All projects combined have a total capacity of more than one gigawatt.
Our innovative IGBT-based rectifier solution combined with carefully designed medium-voltage components and our large-scale serial manufacturing guarantees minimum project risk at maximum efficiency and quality.

Hydrogen solutions
Flexible use of renewable energies
Altenso positions itself at the forefront of hydrogen (power-to-gas) solutions, with a clear ambition to foster the development of grid integration and complex engineering of electrolyzer projects.
Grid compliance
Our IGBT-based PCUs allow a smooth grid connection and reactive power management. They provide exceptionally low harmonic distortion and make additional filters or compensators obsolete.

Our solutions
Our Power Conversion Units (PCUs) are basing on an IGBT technology and have a wide DC operation window which enables to work with different types of electrolyzers (PEM, Alkaline, and SOEC). We supply a plug-and-play solution incorporating the rectifier, transformer, medium-voltage switch gear and low voltage compartment in different sizes. All products are tested and carefully integrated for direct implementation at site.
