The RefuSol 333K has a compact design with a volume of just 1.23 square meters, combined with a efficient, transformerless 690 VAC output voltage. According to the company, the possibility exists to connect strings with a maximum output voltage of 1,400 VDC.
The RefuSol 333K has the protection class IP 65. Moreover, the product offers the possibility for connection of multiple inverters. This in turn results in low losses as well as a cost effective system structure in many fields of applications.
The RefuSol 333K offers a maximum efficiency of more than 98.5 percent with an European efficiency of more than 98.2 percent. The inverter is cooled via a temperature controlled air cooling system.
The product has a CE certification with UL and CSA in preparation as the company states. The anti-islanding protection prevents the back-feeding of inverter generated power to the grid in the event of a breakdown. According to the company, the inverter weighs approximately 600 kilograms.
