“24H sun” is the Fronius vision of how energy will be supplied in the coming decades. The Fronius Symo Hybrid is a major step towards this vision. Boasting power categories ranging from 3.0 to 5.0 kW, the transformerless inverter allows unused energy from a photovoltaic system to be stored in a battery. The result: maximum self-consumption of the available power and maximum energy independence. Excess solar power can thus be used at times when generating conditions are poor or impossible. With the emergency power function, the household can enjoy an optimum electricity supply even during power outages. Perfect system configuration and visualisation are provided by the built-in web server with graphical interface, WLAN and Ethernet. In addition, the DC coupling on the battery guarantees maximum efficiency of the overall system.
