Three-phase Fronius ECO WiFi inverter
The three-phase Fronius ECO inverter available in power ratings of 25.0 and 27.0 kW optimally meets the requirements of large installations. Thanks to its low weight and SnapINverter assembly system, this transformer-free device enables simple and rapid installation inside or outside the building. With protection rating IP 66, this inverter sets new standards. The use of integrated fuse sockets for modules on both poles and optional overvoltage protection means there is no need to use DC connection boxes.
