The heart and brain of every photovoltaic (PV) system is the inverter, which converts direct current generated by solar panels into alternating current that can be used in a home or business. The inverter also optimizes the yield, controls energy flows, and checks the function of the PV system.
One of the leading manufacturers of inverters for PV systems is Fronius Solar Energy based in Wels, Austria. A division of Fronius International GmbH, Fronius Solar Energy introduced its first inverter, the Sunrise, back in 1994, and it has been a market leader ever since.
