REFUsol 50K-3T
The power for mid-size PV plants


  • Multi MPP-Tracking
  • Separate connection area
  • New REFUsol Generation


The completely new REFUsol inverter is developed for a maximum of flexibility in commercial and industrial PV systems.

With three MPP trackers, each system design can be realized, including different orientations and tilts. Compact dimensions paired with a high power density per weight gives more installation location flexibility – on the rooftop or on ground mounted systems. With 50 kVA output power, it fits to any project size.

The inverters can be connected on the same RS485 Bus for monitoring and Park Control applications without the need for reconfiguration. Therefore, the devices are also best suited for extending existing PV plants equipped with legacy REFUsol inverters.

Surge protection devices type II are pre-equipped on the DC side for additional protection. Four digital inputs support the feed-in management (i.e. 0 %, 30 %, 60 %, 100%).

The REFUlog monitoring portal comes for free with each inverter during the warranty period of 5 years. The Ethernet Stick for internet connection is supplied as standard, a WiFi Stick can be ordered as accessory.
