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 current CER snapshot lists M8, M9 and M10, approved 7 July 2026 and expiring 7 July 2029. | 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. |
| Warranty scope | Australia; the exact SMILE-M-S inverter warranty provides ten years for the named M8, M9 and M10 family. | Deye warranty Version 2.16 covers all SUN-series AU-type hybrid inverters and explicitly includes the 7, 7.6, 8 and 10 kW SG05LP1-AU-AM2-P pattern for ten years, with narrower coverage in years six to ten. |
| Warranty remedy | AlphaESS may repair, replace or otherwise settle an accepted claim under the governing terms. | Deye may repair or replace using new or reconditioned parts or products. |
| Labour and reinstallation | Reasonable accepted claim costs may be covered, subject to authorization and installer participation. Full removal and reinstallation reimbursement is not promised unconditionally. | Repair labour applies in years one to five; uninstalling and reinstalling are excluded. Labour is excluded in years six to ten. Excluded. |
| Freight | Replacement-part freight is covered within the stated process; broader transport is not unconditional. | Non-expedited shipment from Deye within Australia and New Zealand is covered; transport damage and broader freight are excluded or not stated. |
| Transfer and registration | Coverage follows the product at the original installation site when the building changes ownership. Purchase, installation and claim evidence are required. | No automatic subsequent-owner transfer right is stated. No pre-registration condition is stated. Claims require serial, invoice, system and fault evidence and must be made within one month after failure. |
| Grid/network approval evidence | The exact model or family appears in the current Australian approved-inverter export. DNSP settings, export limits and site design remain installation-specific. | Single-phase Australian identity. CER product listing does not establish DNSP, site, export-limit, installation or commissioning approval. |

| Review note | This is the inverter layer only. Existing AlphaESS battery records remain separate, and no product-pair recommendation is published. | 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. |
| Register: parts term | Not in the structured register | stated: Ten years applies. Years six to ten exclude LCD and fan components. |
| Register: labour and service | Not in the structured register | conditional: Repair labour is covered in years one to five, but uninstalling and reinstalling are excluded. Labour is excluded in years six to ten. |

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.
