The experiences with these installations influenced the described photovoltaic demonstration project which has been supported by the Commission of the European Communities (DG XVII). A major improvement is the use of an advanced version of the FHG-ISE inverter, leading to a significantly simplified overall installation. In this presentation three examples with different requirements are shown: One is "Bognago", a little village in the Italian Alps. Another one is the "Rotwandhaus", a house of the Deutscher Alpenverein (German Alpine Association) where the combination of a wind generator with a photovoltaic installation is presented. The last project is the "House Langer" where a comparison between two different battery technologies is made. These investigations, supported by the BMFT, lead to conclusions on the suitability o f the two battery technologies used for supplying power to remote areas.enBatterievergleichbattery comparisonBognagoHaus Langerhouse Langerinverternetzfernes Hausproceeded DC/DC-converterremote houseRotwandhausvorgeschalteter DC/DC-WandlerWechselrichter621697conference paper
