Fronius Eco 27.0-3-s Light 27 kw 3 Phase Solar Inverter is a small commercial or huge residential inverter. 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.
