High energy cost and dependency from the electricity grid inspired Deutronic to develop an intelligent system to manage the energy consumption of households or industrial facilities. Using solar cells to gain energy, a sufficient energy storage and Deutronic´s management system is all that is necessary to get independent from public grids. It depends on the user which type of storage technology shall be used. The system was tested with lead-acid batteries as well as with different kinds of lithium cells. The management system can be integrated in new projects as well as in already existing installations. The pilot project is running successfully in our German headquarter since two years. It does not only allow managing the power consumption, it also is able to display the current situation in real time. We expect to be ready for the market during the second half of the year 2018.
