Perfect Welding / Solar Energy / Perfect Charging
FRONIUS THERMAL SOLUTION
Quick and easy hot water preparation with
surplus PV energy using the Fronius Ohmpilot
THE ADVANTAGES AT A GLANCE
/ Increase in the service life of the main heating system
/ Hot water supply using PV energy over 8 months of the year largely possible
/ Increase in self-consumption rate of up to 100%
/ Continuous regulation from 0 to 9 kW for optimum use of the surplus energy
/ Reduction in energy costs

THREE BUSINESS UNITS, ONE GOAL: TO SET THE STANDARD THROUGH TECHNOLOGICAL ADVANCEMENT.
What began in 1945 as a one-man operation now sets technological standards in the fields of welding technology, photovoltaics and battery charging. Today, the
company has around 5,660 employees worldwide and 1,321 patents for product development show the innovative spirit within the company. Sustainable
development means for us to implement environmentally relevant and social aspects equally with economic factors. Our goal has remained constant throughout:
to be the innovation leader.
