The three-phase Fronius Eco in power categories 25.0 and 27.0 kW perfectly meets all the requirements of large-scale installations. Thanks to its light weight and SnapINverter mounting system, this transformerless device can be installed quickly and easily either indoors or outdoors. This inverter series sets new standards with its IP 66 protection class. In addition, its integrated all-pole string fuse holders and optional DC fuse mean that string collection boxes are no longer required.
