Silicon Carbide transistors allow a weight reduction and performance improvement

Peak efficiency ratings of up to 98.7% on a wide input voltage range

REFUsol 020K-SCI model has enabled REFUsol to receive Plus X Award for this inverter using Silicon Carbide technology.

With a nominal power of 20KW AC, the transformerless inverter, which provides one MPPT and a peak efficiency of 98.7%, has been distinguished for innovation, high quality, functionality and ecology. The system uses specific power modules from Danfoss. One of the modules uses Silicon Carbide MOSFET Transistors from Rohm.

System Plus Consulting is publishing the reverse costing report of the REFUsol 020K-SCI.

Based on a complete teardown analysis, the report provides the bill-of-material of the product, an estimation of the production cost of the inverter as well as physical and economical analysis of Danfoss power modules.
