AU Warranty scope

Current text

Fronius International Limited Warranty EN_0326 applies to Fronius inverters purchased on or after 1 June 2026. Australia receives five years Warranty Plus without registration and a total of ten years after eligible Solar.web registration within 30 months of ex-works delivery. Section 2.2 excludes components subject to wear, including DC isolators, fuses, varistors and surge arresters, from the warranty. This string-only Verto 27.0 record does not inherit Verto Plus backup functions.

AU Support Note

Before

Fronius Australia Pty Ltd provides the local warranty and service pathway. This record does not transfer Verto Plus battery or backup functions to the string-only Verto 27.0.

After

Fronius Australia Pty Ltd provides the local warranty and service pathway. This record does not transfer Verto Plus battery or backup functions to the string-only Verto 27.0. Fronius’s 2026 planning specification discloses an IGBT bridge for Verto 27.0 SPD 1+2, article 4,210,402. Its relationship to this record’s retained Type II protection and earlier efficiency-source revision is not established. The semiconductor criterion remains unresolved for the scored configuration; the new document does not change Australian approval, warranty or installation eligibility.

Germany; country group 1. Inverters up to 49 kW receive 10 years (5 years Warranty Plus then 5 years Warranty). Verto 27.0 is inside that band. Solar.web registration within 30 months of factory delivery is required.

AU Warranty conditions

Before

Not previously recorded

After

labour: Warranty Plus covers authorised labour directly associated with removal and replacement; unauthorised costs are excluded.; registration: Five years applies without registration; the free extension to ten years requires eligible Solar.web registration within 30 months of ex-works delivery.; remedy: Fronius may repair, replace with an equivalent or newer product, or issue a current-value credit when repair or replacement is unavailable.; removal reinstallation: Covered only when performed by Fronius or a specialist installer commissioned by Fronius.; transferability: Existing warranty rights transfer with ownership without restarting or expanding the term.; transport: Standard national shipping is covered; express, air or sea transport, customs and export certificates are excluded.
