What’s covered
Manufacturer remedy
PDF5–6 sections 3.1–3.4: BYD chooses repair or replacement; unavailable types may be replaced with similar parts, including used parts equivalent to new in performance/reliability. If not repaired/replaced, performance refunds use BYD-selected remaining-throughput or usable-energy-shortfall formulas. For an inoperable product, refund is maximum claim amount/120 × (120 − months since warranty start). Maximum claim amount is BYD-determined defect-free new market value, not automatically invoice price. PDF8 section 4.5 retains the original warranty period after repair/replacement.
Labour
Unconditional installation or site labour reimbursement is not established. PDF8 section 4.2 permits inspection charges if coverage does not apply or no defect is found. PDF9 out-of-warranty parts/labour/travel costs are separate.
Freight
Ordinary claim freight is not an unconditional entitlement. PDF8 section 4.3 requires replaced items to be available for pickup within four weeks unless agreed otherwise; otherwise BYD may invoice full market price. PDF10 expert-testing and shipping costs fall to the buyer only if the claim is not withdrawn within 14 days of referral notice and the expert decides for BYD; BYD pays in other cases. This dispute rule is not ordinary repair freight cover.
Removal and reinstallation
Unconditional removal and reinstallation reimbursement is not established; no site-work entitlement is inferred from no-charge hardware remedies.
Exclusions
Labour: Unconditional installation or site labour reimbursement is not established. PDF8 section 4.2 permits inspection charges if coverage does not apply or no defect is found. PDF9 out-of-warranty parts/labour/travel costs are separate.
Freight: Ordinary claim freight is not an unconditional entitlement. PDF8 section 4.3 requires replaced items to be available for pickup within four weeks unless agreed otherwise; otherwise BYD may invoice full market price. PDF10 expert-testing and shipping costs fall to the buyer only if the claim is not withdrawn within 14 days of referral notice and the expert decides for BYD; BYD pays in other cases. This dispute rule is not ordinary repair freight cover.
Removal and reinstallation: Unconditional removal and reinstallation reimbursement is not established; no site-work entitlement is inferred from no-charge hardware remedies.
Transferability
PDF1 expressly includes a subsequent owner acquiring the product for their own use with proof of ownership; no separate transfer-registration deadline is stated.
How to make a claim
Start with the original installer or the manufacturer's Australian support channel. Written claim to the BYD partner, or global service if unreachable, with mandatory installation date, invoice, battery configuration/product serial and inverter details (PDF6–7). Notify within 30 days of awareness; installation within one month of warranty start, manual-compliant use and approved operation are conditions (PDF4). Requested performance-data access over the internet applies after a claim (PDF5); this does not establish continuous cloud dependence. No separate initial product-registration requirement is stated.
