REFUsol 333K central inverter

The new and highly efficient central inverter suited for outdoor areas and industrial rooftops - REFUso/ 333K - with its low system costs and an extremely high level of efficiency of over 98.5%. lts compact configuration and its low weight of approximately 850 kg means logistics and infrastructure costs can be reduced considerably.

The high output voltage of 690 VAC enables the parallel operation of several devices on just one transformer. This time-proven technology comes from the wind industry and is clearly cheaper and results in lower loss-levels than several small transformers.

Thanks to the UltraEta® circuit topology, the REFUso/ 333K has a very high peak efficiency of over 98.5%.The efficiency curve has an efficiency of over 98.4% over a wide MPP range. This means high levels of efficiency are also guaranteed at low levels of sunlight.

The high energy yield, ease of installation, efficient operation, use of standard transformers and components used in the wind industry, leads to a significant reduction in BOS and total system cost for large PV systems.
