Matthias Kampert’s farm has been in the family for over 100 years. Nowadays the farm has 130 animals in total. To save electricity, Kampert has installed a photovoltaic system on the roof. The problem is that he also has to milk when the sun is low. The solution is simple. With a powerful battery storage system, Kampert can store the self-generated electricity accumulated throughout the day, increasing his self-consumption. Because TESVOLT storage systems can be expanded even after several years, the dairy farmer can buy a milking robot and make his TESVOLT storage system evolve with his farm.
