Fronius Galvofronius galvo Inverters

The future-proof inverter for small self-consumption systems.

The Fronius Galvo is a single-phase solar inverter equipped with an integrated energy management function. With power categories ranging from 1.5 to 3.1 kW, the Fronius Galvo is perfect for households – and is especially suitable for self-consumption systems. The integrated energy management relay allows the self-consumption component to be maximised. A host of other smart features make the Fronius Galvo one of the most future-proof inverters in its class: for example, the integrated datalogging, the simple connection to the internet by WLAN, or the plug-in card technology for retrofitting additional functions.

  • Integrated datalogging
  • Simple connection to the internet by WLAN
  • Plug-in card technology for retrofitting additional functions.
  • Suitable for all panel technologies (galvanic isolation)
  • Low weight and compact
  • Suitable for indoor and outdoor mounting
  • Simple mounting system
  • Automatic HF transformer switchover
  • Smart Grid Ready
