    How it all began…-

    Three young engineers (Nico, Jakob and Holger) start the INENSUS GmbH based in Clausthal-Zellerfeld, a spin-off from Clausthal University of Technology, Germany, as a service provider for INtegrated ENergy SUpply Systems and decentralized power supply.


    Our first contracts

    The founders acquire the first engineering contracts in the minigrid field with a focus on minigrid design.

  • 2006

    Our first product…

    As its first product, the company develops, manufactures and distributes the AEOLOG, a complete wind and solar monitoring system with 10 and 15m telescopic poles tailored to small-scale wind turbines and detailed site potential analysis for off-grid hybrid systems.


    …and services

    Engineering services for various developers and manufacturers of small-scale wind turbines represents the first solid source of income for the young company.

  • 2007

    Moving out

    INENSUS leaves Clausthal University of Technology and moves its headquarters to Goslar, Germany, under the umbrella of the Energy Research Centre of Lower Saxony.


    Our first project in Africa
