marks 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 | Current CER system rows include 8S, 10S and 12S combinations, approved 13 August 2026 and expiring 31 December 2027. | The current CER snapshot lists M8, M9 and M10, approved 7 July 2026 and expiring 7 July 2029. |
| Warranty scope | Australia; the current warranty names the 8S, 10S and 12S inverter layer for ten years. | Australia; the exact SMILE-M-S inverter warranty provides ten years for the named M8, M9 and M10 family. |
| Warranty remedy | Hoymiles may repair or replace accepted defective product. | AlphaESS may repair, replace or otherwise settle an accepted claim under the governing terms. |
| Labour and reinstallation | Ordinary installer and commissioning labour is excluded unless separately authorized. Removal and reinstallation are not promised. | Reasonable accepted claim costs may be covered, subject to authorization and installer participation. Full removal and reinstallation reimbursement is not promised unconditionally. |
| Freight | Return and replacement logistics are conditional on the approved claim process. | Replacement-part freight is covered within the stated process; broader transport is not unconditional. |
| Transfer and registration | Transfer at the original installation site requires Hoymiles authorization by email. Serial, installation and claim evidence are required. | 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 | The exact model or family appears in the current Australian approved-inverter export.

| Review note | The 5S approval row is not included in the scored family because the current warranty reviewed for this tranche does not name that inverter. The 12S-48B regulator row is an approval fact, not proof of identical warranty scope for the 48B system configuration. | This is the inverter layer only. Existing AlphaESS battery records remain separate, and no product-pair recommendation is published. |

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.
