More information

Hannes Heigl and his family have owned a 6 kWp PV system with a Fronius
Symo 8.2 inverter since 2013. Thanks to the attractive Austrian ÖMAG public
subsidy, the Heigls feed 100% of the yield into the grid.
In August 2014, the family upgraded their system. The new Fronius Energy
Package, which includes the Fronius Symo Hybrid 5.0-3-S, the Fronius Solar Battery
7.5 and a Fronius Smart Meter, generates approximately 3,650 kWh of energy
per annum. The family of four uses ninety percent of the solar power produced
themselves. In addition, a heating element for producing hot water was installed
at the same time, which in turn has had a positive impact on monthly costs.
“Fronius delivers the perfect complete system for storing the electricity we have
generated so that we can use it ourselves. The easy installation of the Fronius
Energy Package using the installation wizard and the fast data connection via
WLAN really impressed me,” reports Hannes Heigl.
