FRONIUS Eco 27.0-3-S Wi-Fi Inverter
FRONIUS ECO 27.0-3-S Wi-Fi inverter
COMPACT INVERTER DESIGNED FOR USE IN LARGE SYSTEMS GENERATING HIGH INCOME
Fronius Eco 27.0-3-S Wi-Fi three-phase inverter. Available in 25.0 kW and 27.0 kW power classes optimally meet the requirements of large installations. Thanks to its light weight and SnapINverter mounting system, this transformerless device can be easily and quickly installed both indoors and outdoors. With an IP 66 protection rating, this inverter sets new standards. The use of integrated chain fuse sockets on both poles and optional DC surge protection means there is no longer a need for chain collection boxes. INPUT DATA
