| Certifications | The 29 July 2026 regulator export lists LVS 4.0 through LVS 24.0 with current approval through 7 December 2026. | The exact BAT-10.1P datasheet lists IEC 62619, IEC 63056, IEC 62040 and UN 38.3; the SMILE-G3-S5 AU system datasheet lists AS 4777.2 and IEC 62109. |
| Warranty scope | Australian residential LVS 4.0–24.0 installed on or after 1 December 2021; Shenzhen BYD Electronic Co., LTD is the named provider. LVS 12.0: ten-year product cover; 60% usable energy until ten years or 35.64 MWh controller-recorded output, whichever first. Default start is the first day after six months from production; written proof of delivery to the first installation site permits the first day after 30 days from delivery. Additional modules’ performance cover starts at their seller-invoice sale date. The scope requires combined usable energy below 50 kWh; exactly 50 kWh is not resolved by the opening scope and later greater-than-50 exclusion. The scored single 12 kWh tower is within scope. Australian Consumer Law rights are additional. | Australia; the 11 October 2024 warranty names SMILE-G3-S5 and BAT-10.1P with a ten-year term, 70% retained capacity and a 3.12 MWh/kWh throughput condition for eligible installations from 1 November 2024. |
| Warranty 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. | Repair or replacement at AlphaESS's option. |
| Labour and reinstallation | 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. Unconditional removal and reinstallation reimbursement is not established; no site-work entitlement is inferred from no-charge hardware remedies. | Clause 2 excludes travelling and accommodation costs of persons for on-site support and does not name labour as covered or excluded. The warranty requires a qualified installer to be available for exchange and re-commissioning (clause 3) and obliges the original installer to assist with replacement (clause 10); reimbursement of necessary and reasonably incurred costs of a valid claim may be claimed with documentary evidence (clauses 2 and 10). Removal and reinstallation are not promised. |
| 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. | Replacement-parts freight is covered for an accepted claim. |
| Transfer and registration | PDF1 expressly includes a subsequent owner acquiring the product for their own use with proof of ownership; no separate transfer-registration deadline is stated. 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. | The warranty is non-transferable except where the products remain installed in a building, in which case it transfers to a later purchaser of that building. Serial registration before a claim, and installation by an SAA-accredited installer with a valid Alpha Installer ID, are required. |
| Grid/network approval evidence | BYD publishes an Australian LVS inverter-compatibility statement. The stored reciprocal path is limited to the exact reviewed Solis S6-EH1P6K-L-PLUS-AU record; final design and DNSP requirements remain site-specific. | The exact AU system is a 5 kW, 230 V single-phase hybrid under AS 4777.2. Current project approval and installer eligibility remain installation-specific. |

| Review note | LVS is a DC battery with no AC transfer device. The manual says it supports external one- and three-phase inverter applications and that internet access is not compulsory; exact backup scope and switching remain inverter-defined. | AlphaESS's current 2026 Australian brochure lists SMILE-G3-S5/B5 with both BAT-10.1P and BAT-9.3S. The battery options coexist; neither is presented as the formal successor to the other. |
| Register: parts term | stated: Ten-year product warranty for the named residential LVS configurations. | Not in the structured register |
| Register: labour and service | not stated: BYD may repair, replace or partially refund at no charge, but the instrument does not promise general installer labour, travel, removal or reinstallation reimbursement. | Not in the structured register |
| Register: transport and freight | not stated: No general owner freight entitlement is stated. Expert-testing shipping is paid by the claimant if the stated dispute conditions are met and the expert decides for BYD; BYD pays in the other stated cases. | Not in the structured register |
| Register: registration | conditional: No separate pre-registration condition is stated. A claim requires invoice and exact installation, battery, inverter and firmware details, and the owner must grant requested internet access to performance data after reporting a claim. | Not in the structured register |

These checks sit beside the benchmark score. They are site, tariff and contract questions that no product score can settle.
Ask for every model number to appear on the quote and order. The Clean Energy Council product lists are live: STC creation requires listed products at installation, and network requirements may also depend on current approval.
Have the retailer state the supply phase, inverter connection limit, export limit and any export-control cost. The local network connection agreement, not a generic datasheet, determines those settings. See the Australian Government's connection guidance.
Ask which bills or interval data, tariff, feed-in rate, export limit and future loads support the savings and payback claim. Self-consumed electricity and tariff timing usually matter more than a headline feed-in rate. See the system sizing and battery savings guidance.
Define the usable energy, output power, backed-up circuits and outage behaviour. Confirm whether VPP participation, an internet connection, or an additional controller changes the configuration, reserve level, warranty or support path.
Keep the retailer, installer, manufacturer warranty and escalation path in the contract. Australian Consumer Law guarantees apply separately from any manufacturer warranty; where one business supplied both product and installation, it is generally responsible for the remedy. See the ACCC guidance.
