Technical datasheet Electrifying Innovations For open field sites and factories The REFUso/333K is the new, highly efficient central inverter for open field sites and industrial rooftops. Low system costs and an extremely high level of efficiency of over 98 4% are just two of the many good reasons to use this model for large- scale projects. Operated together, just three of these devices provide one megawatt of power Despite being developed for high power outputs, this inverter is elegantly reserved in terms of its weight and the space it needs. A weight of just 850 kg, spread throughout a compact housing, is beneficial in terms of transport and infra- structure costs. Thanks to a standardized voltage levelof690VAC, this inverter is the ideal solution for developers of large-scale PV systems. Easy installation
