Fronius IG TL Inverterfronius IG TLs

Best in class with system monitoring as standard.

The Fronius IG TL combines all the benefits of a transformerless inverter with the high level of innovation and quality expected of Fronius. With power categories ranging from 3 to 5 kW, the Fronius IG TL is perfect for systems of any size from detached houses to agricultural or commercial premises. Standard system monitoring makes it the most future proof transformerless inverter on the market, and the one that will produce the most reliable yield.

  • East/west ready!
  • Improved DCAC board design
  • Night-time display for data access after daylight hours (night-time consumption less than 1w)
  • Wide input voltage range allowing a diverse range of solar array combinations
  • Accurate and efficient Maximum Power Point Tracking with the Module Manager
  • Generic USB stick can be used for easy system/data monitoring as well as inverter updating
  • String malfunction detection with built in signalling relay
