Performance and reliability are what counts in large PV systems. The second generation of the string inverter REFUsol 40K/46K offers both. With up to 46 kVA output power for medium voltage feed-in and its patented 5 level UltraEta® topology, it generates the best possible energy yield at every irradiation level. The inverter design with passive cooling without external fan eliminates costly maintenance works.

The new DC and AC terminals using latest Phoenix Contact T-LOX technology allow fast connection of aluminum and copper wires up to cross sections of 50 mm². Thanks to the reduction to one single DC input, the inverter offers multiple options on the DC external combiner box.

Each solar inverter can be connected to our cloudbased monitoring portal REFUlog using Ethernet or RS485 connections, offering professional monitoring functionality.
