In large megawatt-class solar parks, performance and reliability count - the new generation of 
 REFUsol 40K / 46K offers both: up to 46 kVA output power for medium-voltage feed - thanks to the patented 5-level UltraEta® topology, the inverter achieves consistently high energy yields with every irradiation. The device concept with passive cooling does not need an external fan and thus avoids costly maintenance work. 
 The new DC and AC connection with Phoenix 
 Contact T-LOX technology enables aluminum and copper lines up to a cross-section of 50 mm² to be connected in a matter of seconds. By reducing to a DC connection on the solar inverter, a large number of external DC connection boxes can be used. 
 Every solar inverter is connected to the cloud-based monitoring portal REFUlog via Ethernet or optionally also RS485 and thus benefits from the professional monitoring functions.
