Grid-tie solar inverter Refusol 333K трёхфазный

REFUsol 333K is a new, highly efficient central inverter for places in the open field and industrial roofs. Low system cost and extremely high level of efficiency of more than 98.4% are just two of the many positive reasons to use this model for large-scale projects. Three inverters that are managed together, provide one megawatt of power.
Despite the fact that the inverter is designed to provide high output power, this device elegantly protected in terms of its weight and
space he needs. Weight only 850 kg, around the common compact housing, convenient in terms of transportation and infrastructure costs. Thanks to a standardized voltage level of 690 V AC, the inverter is the perfect solution for large-scale photovoltaic systems developers
