Warranty period
Exact KH family: 120 months
The Australian policy names KH7, KH8, KH9, KH9.9, KH10 and KH10.5 and provides 120 months from installation, capped at 132 months from manufacture.
Inspection condition from year six
The published terms require annual inspection by an authorised party from year six for continued coverage.
What’s covered
Repair or replacement
FoxESS may repair or replace an inverter confirmed defective under the policy. The replacement continues only for the balance of the original term.
Local Australian support
The policy is issued through FoxESS Australia and publishes a local importer, service email and phone contact.
Exclusions
Inspection and registration conditions: Failure to meet the policy's registration, commissioning or later inspection conditions can affect eligibility.
Installation and external causes: Incorrect installation, wiring, unauthorised work, physical damage, environmental events and operation outside the manual are excluded.
Conditional service support: Service and transport rebates depend on approval, return timing and policy conditions; full end-user labour is not guaranteed.
Unapproved replacement: Replacing the product without prior FoxESS approval can invalidate the associated claim.
Transferability
No explicit transfer process for a later property owner is stated. Confirm the registered end user and remaining term with FoxESS Australia before relying on cover.
How to make a claim
The installer contacts FoxESS with model, serial number, fault code, evidence and site details. FoxESS may diagnose remotely before issuing an RMA or replacement approval.
