REFUsol 023K-460VAC
Ideal solution for medium-voltage applications
With an output voltage of 460 volts and an input voltage range of 575 to 850 volts, the REFUsol 023K-460 VAC is the ideal solution for medium-voltage applications on large-scale PV sites. It has an efficiency factor of more than 98%.
Convection cooling
The high efficiency enables convection cooling. This ensures, in addition to noise-free cooling, the maintenance-free inner workings of the inverter.
Plug & play installation
Installation is safe and easy with simple plug connections and low weight, because the devices also remain closed during installation. This means low installation costs.
It is easy to network
The data logger, RS-485 interface and Ethernet connection turn the inverter if required into a data networker. Inverters can, if required, also be integrated into a network with the radio module REFUconnect via W-LAN.
