Having been interested in photovoltaics for a number of years, Christian Kasberger
decided in 2012 to have a PV system installed on the roof of his own
home. At first the system was fitted with a Fronius Symo with an annual production
of 7,500 kWh. With a self-consumption rate of 30%, the PV system also
delivered a dramatic cut in his energy bills.

In August 2014 the existing system received a rather special upgrade in the
shape of a Fronius Symo Hybrid 4.0 and a Fronius Solar Battery 7.5. Now the
Kasberger family can use their hybrid PV system to store excess energy in a
battery and maximise their self-consumption rate.
“For me, energy independence is an increasingly important issue. Thanks to the
Fronius Symo Hybrid we can largely free ourselves from the public grid. Decentralised
power generation coupled with a local storage facility allows us to make our
contribution towards reducing the amount of power generated from fossil fuels
and nuclear sources,” explains Christian Kasberger.
