Three companies from Germany and Austria have equipped the Hochleckenhaus with a off-grid and energy Management system for the Austrian Alpine Association. The hut can now boast of having the most advanced off-grid network in the Alpine region.

Some 1,000 visitors a day are served up Austrian delicacies and find accommodation at the popular destination on Lake Attersee. To better manage the energy, that is needed for this task the Austrian Alpine Association assigned the QINOUS GmbH, a Berlin-based manufacturer of turnkey energy storage systems, together with Solare Energie and Bridge Executive Consulting, to install an energy management system. In addition to that a 17 kW pv plant was mounted to the roof. The plant is feeding to a 61 kW battery storage system.

This project, which uses the first suitable energy storage system of an industrial design and smart metering, is also quite interesting for the huts of other organisations like for example the German Alpine Club (Deutscher Alpenverein DAV), as the number of people interested in mountain trips is constantly growing. The higher capacity utilization not only requires additional buildings, but also a stronger and more reliable energy supply ", says Robert Kolbitsch, head of the department of huts, paths and climbing facilities of the DAV.

A further advantage of the new system is the resulting clarity. The QINOUS off-grid network and energy management system not only monitors and controls the storage system, the PV plant and the gas generators, it can also monitor and log gas consumption for the individual generators and the kitchen separately as well as domestic water consumption.

The PV plant including the inverters was supplied and installed by the Austrian company Solare Energie GmbH, which is very experienced in the installation of solar plants in the mountain locations. The demanding retrofitting of the main load control cabinet and the connection of the new battery system was conducted by the managing director and master of craftsman in electro technology Mr. Heimo Modre personally.

Concept development, planning and project management were handled by Bridge Executive Consultingwhich also designed and implemented the smart metering system for the seamless recording of generation and consumption data, and contributed its many years of experience in military and civil projects in alpine locations. The demanding engineering of the metrology and its communication interfaces as well as the general management of the project were conducted by the managing director Stefan Perlot, M.Eng. personally on site.

The storage specialist ADS-TEC will be presenting its new storage series in hall B1, booth 230 for the first time at “electrical energy storage” (ees) within the framework of “The smarter E Europe / Intersolar Europe 2019”. The scalable series is particularly flexible with regard in terms of capacity and performance. In addition to an indoor solution, the portfolio from this medium power range is also supplemented by an outdoor version. The integrated emergency power function makes the storage system suitable for a variety of storage applications.

In the first half of 2019, solar, wind and other renewable sources accounted for 44 percent of the electricity consumed in Germany, marking a record high. Preliminary calculations by the Centre for Solar Energy and Hydrogen Research Baden-Württemberg (ZSW) and the German Federal Association of Energy and Water Management (BDEW) yielded this figure. Renewables had accounted for 39 percent of electricity consumption in the first half of 2018.
