The AC Elwa-E from MyPV communicates with the energy management system of the building or the battery management system. Smart homes and photovoltaic storage systems are all the rage. Hardly anyone thinks about the fact that typical PV-systems produce far more energy a day than can be consumed in the house. That means that the battery is fully loaded and that excess-power goes to the grid afterwards.
This is exactly the starting-point for the AC Elwa-E from myPV: It communicates with the energy-management system of the building or the battery management system. As far as excess energy is detected respectively the management-system clears the AC Elwa-E, energy is stored in hot-water. In this way we can easily add 10 up to 20 Kilowatt hours of extra storage capacity. In a simple web-interface the installed battery respectively the energy-management-system can be selected. (
