More information

“We try to use the largest possible amount of the solar energy we produce ourselves,”
reports system owner Markus Brandstötter about his PV system. “Using
three inverters - a Fronius Symo, a Fronius Symo Hybrid and a Fronius IG Plus - we
produce approximately 18,000 kWh of solar power. We also have a Fronius Solar
Battery in the overall system, which allows us to store the energy we produce.”
 
The 17.57 kWp system is a real showpiece of efficient self-consumption. A
Loxone Miniserver is responsible for the energy management by intelligently
controlling the numerous consumers around the house.
 
There are six residential units in the refurbished farmhouse and the lighting
for all of them is mainly powered by solar energy. Other consumers include an
electric car, the swimming pool pump, a fountain system, the washing machine,
the wood chip heating and wood chip ventilation systems. Even the hot water is
produced by a boiler with a cartridge heater using PV power. The result is an
excellent degree of self-sufficiency of up to 60%.
 
“The Loxone home automation system was easy to combine with the Fronius
inverter - that‘s what I call Plug & Play!” says Brandstötter.
