What’s covered
Manufacturer remedy
Fronius may, at its discretion, repair the product, replace it with an equivalent product of corresponding design and condition or with a newer product, or, if a replacement product is not available and repair is impossible or possible only at disproportionate cost, give a credit towards a new Fronius product calculated as 'Selling price * (100 % - useful life/performance warranty period)' (clause 5.1). Under Fronius Warranty Plus the spare part or replacement device may be new or reconditioned, or its market value may be reimbursed (clauses 6.3.1 and 13.4).
Labour
Labour directly associated with removal and replacement is covered when carried out by Fronius or a specialist installer commissioned by Fronius; costs not authorised in advance in writing by Fronius are not borne (clauses 6.3.1 and 6.3.3).
Freight
Normal domestic shipping is covered.
Removal and reinstallation
Approved removal and replacement are covered; additional travel is excluded.
Exclusions
Removal and reinstallation: Approved removal and replacement are covered; additional travel is excluded.
Transferability
The remaining warranty automatically transfers with the covered product.
How to make a claim
Start with the original installer or the manufacturer's Australian support channel. Revision EN_0326 refers in clause 1.2 to registered products but sets out no registration procedure or deadline; cover requires purchase as a new device from Fronius, an authorised dealer or a professional installer, and commissioning by a professional installer (clause 2.2). The operating manual states that, where a warranty applies, the product should be registered at https://warranty.fronius.com/ to activate or extend the warranty.
