Fronius Symo Hybrid Three Phase Inverters

Fronius Symo Hybrid Three Phase Inverters

The Fronius Symo Hybrid is the heart of the 24H Sun storage solution.

Boasting power categories ranging from 3.0 to 5.0 kW, the three-phase inverter allows excess 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 (Retrofitting of the emergency power function is possible from mid 2016, using a software update). 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.
