What sets the price of a system with Fronius inverters?
Installers quote Fronius inverters as part of a whole system, so there is no stand-alone price we can source. System size, roof type, switchboard work and the federal STC rebate move the price far more than the brand. Our solar price guide covers installed cost by system size, and the STC rebate guide shows what comes off it in your zone.
Key features
- Free 10-year Fronius Warranty Plus, covering materials, servicing and transport, when the inverter is registered on Solar.web
- Paid extension up to 15 years
- GEN24 Plus hybrids from 3.0 to 10.0 kW single-phase and 3.0 to 12.0 kW three-phase
Things to check before you buy
- The 10-year cover depends on registration: for inverters commissioned from 1 June 2026 it must be on Solar.web within 30 months of delivery, so make sure your installer registers it

5 years standard, 10 years when registered on Solar.web (Fronius Australia, warranty models, checked 10 October 2026). Read the warranty document for the exact model you're quoted: conditions such as registration, cycles or capacity retention vary.

Fronius is headquartered in Austria. Ask your installer where the stock they're quoting was made, as manufacturing locations vary by product line.
