Grid-tie solar inverter Refusol AE3LT23

Transformerless inverter REFUsol 023K with 460VAC completes the range of three-phase inverters Refusol 008K-020K. Since the output voltage 460 V and the input voltage range from 575 to 850, REFUsol 023K-460 VAC is the ideal choice for medium voltage applications in high-power solar system. efficiency levels in this inverter more than 98%. Like other inverters REFUsol, 023K-460VAC is also working with fast and accurate tracking systems REFUsol MPP. Data logger, interface RS485
and easy Ethernet connection to transfer data. It can be quickly and easily configured via the network, and our REFUconnect solution - even wirelessly. Using a web-based tool REFUlog assessment, you can analyze the capacity of the budget and operation of the system. Here you can fully concentrate on the parameters, curves and values, since there is no need to worry about saving
