Puchheim near Munich, October 11, 2021 – Proton Motor Fuel Cell GmbH congratulates its customer and partner, Euskirchen-based UMSTRO GmbH (, on the successful realization of the new “energy trailer” called “MoSolFCA” (Mobile Solar FuelCell Aggregate). This system is a mobile power supply as an environmentally friendly variant of comparable generator sets. Thanks also to the client of the green “sandwich box trailer”, which represents an intelligent combination of renewable energy sources: The Institute of Meteorology and Climate Research as the Garmisch-Partenkirchen location of KIT (Karlsruhe Institute of Technology, With regard to the power supply of measuring stations in productive field use – as is currently the part of the MOSES project (Modular Observation Solutions for Earth Systems) – the development of a CO2-free, transportable and self-sufficient energy supply system was necessary. During the approximately one-year design phase, UMSTRO integrated the “PM Module S8” fuel cell supplied by Proton Motor as a component with an output of 8.4 kW together with a 10 kWh battery storage system and the photovoltaic modules (approx. 3 kWp) in an individual hybrid solution. This ensures year-round operation for the institute for power supply with at least 2.5 kW continuous power.

Uninterruptible power supply guaranteed

In the past four months, the unofficial commissioning of the innovative energy trailer has been tested on the outdoor exhibition grounds, so that all responsible people were happy about the public presentation end of September. In the context of this summer’s flood in some German areas, conventional diesel generators had to be switched off mainly because of their volume as well as odor and pollution for the environment. As a result, inhabitants of the affected regions were sometimes sporadically or were completely undersupplied with electricity. The UMSTRO energy trailer could offer an intelligent opportunity to improve civil protection, especially at the municipal level. This benefits not only responsible state government agencies, but municipalities with their fire brigades and departments of the Federal Agency for Technical Relief are guaranteed a green uninterruptible power supply specifically to support professional emergency work.
