Technical datasheet REFUsol 023K- 460 VAC String inverters for medium voltage systems 460 VAC for medium voltage applications Highest Easy efficiency (98.3%) installation Outdoor (IP65) Maintenance The transformerless REFUsol 023K string inverter with 460 VAC complements the product range between the 008K– 020K string inverters with 400 VAC and the high-power REFUsol 333K central inverter with 690 VAC. With an output voltage of 460 V and an input voltage range from 575 to 850 V, the REFUsol 023K- 460 VAC is the perfect choice for medium voltage applications in large-scale PV plants. It has an efficiency level of more than 98%. Like the other inverters in the REFUsol product line, the REFUsol 023K- 460 VAC also works with the fast and precise REFUsol MPP tracking system. The data-logger, RS485 interface and Ethernet connection make data communication easy. It can be configured quickly and easily via LAN. These inverters can be integrated into a network using W-LAN if required. free To do this, they just have to be connected to the REFUconnect radio module. All configuration and monitoring functions can then also be used wirelessly. You can analyze the power budget of the systems being operated using the web-based evaluation tool REFUlog. Here you can focus fully on parameters, curves and values as there is no need to worry about maintaining the 023K- 460 VAC. It functions with maintenance-free convection cooling.
