Full scorecardmarks the better value on rows where a higher number is better. Temperature coefficient counts as higher when it is closer to zero. Size measures such as rated power carry no marker, because a larger product is a different choice rather than a better one.

| Certifications | The CER export last modified 10 August 2026 lists exact 7, 7.6, 8 and 10 kW AU-AM2-P codes through 20 July 2029., The exact Australian datasheet names AS/NZS 4777.2 and IEC/EN 62109-1/-2. | The current CER snapshot lists M8, M9 and M10, approved 7 July 2026 and expiring 7 July 2029. |
| Warranty scope | Current AU library V2.17, reviewed 4 October 2026, explicitly names the 7/7.6/8/10 kW SG05LP1-AU-AM2-P pattern for ten years. It states effect from 1 November 2023 and serial 2311XXXXXX and later. Term starts at original purchase from Deye, capped at ten years and six months from factory delivery, subject to a sales-order period/formal contract. Actual unit serial and applicable contract must be checked. Years six to ten exclude LCD, fan, repair labour, taxes/duties and installer costs; CT/meter two years and data logger five years are separate accessory terms. | Australia; the exact SMILE-M-S inverter warranty provides ten years for the named M8, M9 and M10 family. |
| Warranty remedy | Deye selects repair or replacement using new/reconditioned or equivalent-function products/parts. Replacement cover lasts the original remaining term or 90 days from return shipment, whichever is later; it does not restart ten years. Approved disputed third-party testing is initially paid by the buyer and reimbursed if the claim proves valid. The policy preserves Australian Consumer Law rights. | AlphaESS may repair, replace or otherwise settle an accepted claim under the governing terms. |
| Labour and reinstallation | Repair labour applies in years one to five; years six to ten exclude repair labour, LCD and fan. Installer installation and on-site inspection fees, uninstalling and reinstalling are excluded. Excluded. | Reasonable accepted claim costs may be covered, subject to authorization and installer participation. Full removal and reinstallation reimbursement is not promised unconditionally. |
| Freight | The policy covers non-expedited shipment of repaired/replacement product from Deye within Australia and New Zealand without a stated second-five-year exclusion in this clause. Return freight is not established; transport/carrier mishandling damage is excluded. This does not promise all claim logistics costs. | Replacement-part freight is covered within the stated process; broader transport is not unconditional. |
| Transfer and registration | No automatic subsequent-owner transfer right is stated. No initial pre-registration condition is stated. Claim within one month after failure with invoice, exact model/serial, installation/failure dates, system/fault/log evidence and requested root-analysis testing. Actual serial 2311XXXXXX or later and the applicable sales contract govern coverage. | Coverage follows the product at the original installation site when the building changes ownership. Purchase, installation and claim evidence are required. |
| Grid/network approval evidence | Single-phase Australian identity. CER product listing does not establish DNSP, site, export-limit, installation or commissioning approval. | The exact model or family appears in the current Australian approved-inverter export. DNSP settings, export limits and site design remain installation-specific. |

| Review note | SUN-10K-SG05LP1-AU-AM2-P is listed at 10 kW in the current CER export. External switching and battery requirements remain outside this independent inverter record. | This is the inverter layer only. Existing AlphaESS battery records remain separate, and no product-pair recommendation is published. The exact M8/M9/M10 inverter manual specifies Smart Fan Cooling, with noise below 45 dB(A) at 1 m. These models are not documented as fanless; natural cooling in the same manual applies to the separate lower-power M5/M3.6/M5-B models. |

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.
Confirm the proposed inverter phase, PV input design, battery pairing and export-control configuration against the final connection agreement. A suitable product can still require a different site design or control setting.
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.
A score lead is only meaningful inside this shared class or tier. Weigh it against the specification and evidence rows above before deciding.
Both products are scored in the Inverter class, on the same rubric weighting. Scores are not comparable across classes or tiers. Full methodology.
