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 commercial storage system manufacturer TESVOLT has supplied a battery storage system for the Coburger Hütte mountain refuge owned by the German Alpine Club (DAV) in Tyrol, Austria. The storage system, with a capacity of 77 kWh, replaces the old lead-acid battery and increases the solar power consumption of the cabin, which is fitted with a 16 kWp solar power system. The entire energy supply installation is tailored to meet the DAV’s stringent environmental and sustainability criteria for mountain regions, and will reduce the consumption of rapeseed oil as fuel.
