What a Fronius inverter costs in October 2026
The one public anchor for a Fronius price is the list price on an Australian electrical supply site, read 27 October 2026: ex GST as published, with GST added in the next column, supply only. Installers buy below list and sell above it, so the inverter line on a quote should sit close to these figures plus margin, with a model number beside it.
