| Certifications | The CER export last modified 10 August 2026 lists all five exact AU family codes through 11 March 2029., The exact Australian product page publishes an AS/NZS 4777.2 and IEC 62109 certificate. | The current CER snapshot lists M8, M9 and M10, approved 7 July 2026 and expiring 7 July 2029. |
| Warranty scope | Ginlong warranty terms Version Solis-20240802-GL apply to eligible Australian Solis inverters purchased after 1 January 2024. Five years is standard; the additional five years is conditional on registration, maintained SolisCloud connection and accredited installation. | Australia; the exact SMILE-M-S inverter warranty provides ten years for the named M8, M9 and M10 family. |
| Warranty remedy | Repair, replacement, refund or credit is at Ginlong Solis or Solis Australasia's election. | AlphaESS may repair, replace or otherwise settle an accepted claim under the governing terms. |
| Labour and reinstallation | Access, labour, removal and installation are excluded unless separately agreed in writing. Excluded unless separately agreed in writing. | Reasonable accepted claim costs may be covered, subject to authorization and installer participation. Full removal and reinstallation reimbursement is not promised unconditionally. |
| Freight | Transport is excluded unless separately agreed; additional freight applies beyond 50 km from the nearest authorised service agent. | Replacement-part freight is covered within the stated process; broader transport is not unconditional. |
| Transfer and registration | The transfer clauses conflict; written approval and ownership evidence may be required, so automatic transfer is not assumed. The additional five years requires SolisCloud registration, maintained connection and accredited installation. | 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 | Three-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 | S6-EH3P15K02-NV-YD-L-AU is the highest exact current model. 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. |
| Register: parts term | conditional: Five years is standard. A published additional five years applies to eligible inverters up to 110 kW when registration, continuous SolisCloud connection and accredited installation conditions are met. | Not in the structured register |
| Register: labour and service | excluded: Access, labour, removal and installation costs are excluded unless Solis Australasia separately agrees in writing. | Not in the structured register |
| Register: transport and freight | excluded: Transport is excluded unless separately agreed. The customer also bears additional freight beyond 50 km from the nearest authorised service agent. | Not in the structured register |
| Register: registration | conditional: The inverter must be registered on SolisCloud and remain connected for the published additional five years. Accredited installation and maintenance are also conditions. | Not in the structured register |
| Register: transferability | conditional: The document first requires written approval, then states transfer is possible with ownership and proof-of-purchase evidence. Automatic transfer is not assumed. | 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.
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.
