In the case of the hotel project in South Tyrol, the aim was to create sufficient charging infrastructure or charging power for the guests around the clock. The existing grid connection was not sufficient for this and the PV system mostly produced surplus when the guests were on the road with their cars, namely during the day. Thus Lynus came into play.

In order to implement this project, the existing PV system was first integrated into Lynus. Based on the data of this PV plant and the desired charging infrastructure, the size of the battery storage was dimensioned. Lynus supplied everything from one source. From the battery storage and the charging stations to the software for the EMS. The delivery and installation was also organized and implemented by Lynus and its partners. Thus, it is now possible to temporarily store excess energy from the PV system in the battery storage during the day and then make it available again for the charging stations at a later time. This means that when the limit of the grid connection is reached, the battery adds the remaining power. Thus, the full power of the battery and that of the grid connection is utilized. At the same time, the maximum power from the grid connection is never exceeded. If the energy from the battery and the grid storage is no longer sufficient, the charging stations are throttled in the last instance depending on their prioritization. Thanks to Lynus, it has thus been possible to avoid having to increase the grid connection on site and still have the desired and necessary charging power of the charging stations available.
