TC500K3

Product description

The output side of isolation type grid-connected inverters can be directly connected to low voltage grid. The fourth generation NPT technology applied in the IGBT module and amorphous isolation transformer has extremely promoted the system efficiency, that Max. Conversion efficient is 97.7% as well as Euro efficiency reaches up to 97.2%. A variety of circuit and hot cross simulation technology realize the optimization design of power circuit; guarantee the excellent power quality output and inverter’s long-term stable operation.
