| Certifications | The CER export last modified 10 August 2026 lists all six exact ESI T1 codes through 28 May 2029., Australian factory warranty Version 2.4 explicitly names ESI 5-12K-T1. | The current CER snapshot lists M8, M9 and M10, approved 7 July 2026 and expiring 7 July 2029. |
| Warranty scope | SOFARSOLAR Australian factory warranty Version 2.4 explicitly covers ESI 5-12K-T1 for 120 months. Necessary product labour and one freight movement are included, while third-party site costs and broader transport remain excluded or discretionary. | Australia; the exact SMILE-M-S inverter warranty provides ten years for the named M8, M9 and M10 family. |
| Warranty remedy | SOFAR may repair on or off site, replace, or pay repair or replacement costs. | AlphaESS may repair, replace or otherwise settle an accepted claim under the governing terms. |
| Labour and reinstallation | Necessary product labour is covered; third-party site labour is excluded unless SOFAR authorises a discretionary rebate. No unconditional full removal and reinstallation entitlement is stated. | Reasonable accepted claim costs may be covered, subject to authorization and installer participation. Full removal and reinstallation reimbursement is not promised unconditionally. |
| Freight | One freight movement to the end user is covered; express, travel and broader transport are excluded. | 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 baseline registration or continuous cloud condition is stated. Claims require serial, invoice, fault and system evidence and must be reported within one month. | 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. |
| Local product pathway | No separate local pathway recorded | No separate local pathway recorded |
| Buyer evidence | Ready (100% direct coverage): Local availability, buyer evidence, and the publication threshold are confirmed. | Ready (100% direct coverage): Local availability, buyer evidence, and the publication threshold are confirmed. |

| Review note | ESI-12K-T1 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 | stated: The exact ESI 5-12K-T1 family receives a 120-month factory warranty. | Not in the structured register |
| Register: labour and service | conditional: Necessary product labour is covered, but third-party personnel, travel and accommodation are excluded. An on-site service rebate is discretionary and requires prior authorisation and a confirmed defect. | Not in the structured register |
| Register: transport and freight | conditional: One freight movement to the end user is covered. Other transport, travel and express delivery are excluded. | Not in the structured register |
| Register: registration | not stated: No baseline product registration or continuous cloud condition is stated. A claim requires model, serial, invoice, fault and system information and reporting within one month. | 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.
