| Certifications | The exact V1.7 Australian datasheet lists IEC 62109-1/-2, IEC 61727, EN 50549, G98, G99, AS 4777.2, VDE-AR-N 4105, CEI 0-21 and VFR., The 4 September 2026 CER inverter export still lists the eight exact AS4777-2 2020 configurations through 25 September 2026. X1-MINI-0.8K-G4 is manufacturer-published and remains absent from the current CER export. | The current CER snapshot lists M8, M9 and M10, approved 7 July 2026 and expiring 7 July 2029. |
| Warranty scope | Australia; the current linked SolaX warranty PDF explicitly names X1-MINI-0.6K/0.7K/1.1K/1.5K/2.0K/2.5K/3K/3.3K-G4 for 12 years. Authorised supply, installation, activation and registration conditions apply. | Australia; the exact SMILE-M-S inverter warranty provides ten years for the named M8, M9 and M10 family. |
| Warranty remedy | Software correction, repair on or off site, or an equivalent repaired, refurbished, upgraded or new substitute at SolaX's option. | AlphaESS may repair, replace or otherwise settle an accepted claim under the governing terms. |
| Labour and reinstallation | Travel, subsistence, on-site installation, modification and normal maintenance are excluded; no uncapped third-party labour entitlement is stated. Full removal and reinstallation costs are not stated as an unconditional entitlement. | Reasonable accepted claim costs may be covered, subject to authorization and installer participation. Full removal and reinstallation reimbursement is not promised unconditionally. |
| Freight | Normal ground transport in specified Australian areas is covered up to AUD 200 per case; excess and alternative transport costs remain with the claimant. | Replacement-part freight is covered within the stated process; broader transport is not unconditional. |
| Transfer and registration | No automatic subsequent-owner transfer right was found in the current linked terms. Authorised supply, installation, activation and SolaXCloud warranty registration are required by the governing terms. | 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 220/230/240 V on-grid string-inverter family. The exact queued Australian approval identities carry the AS4777-2 2020 suffix. DNSP acceptance and export settings remain site-specific. | 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 | The live Australian page still names X1-MINI-3.3K-G4. The current manufacturer family also publishes X1-MINI-0.8K-G4, which remains absent from the current CER export and is deliberately excluded. The listing still expires on 25 September 2026. This is a freshness recheck, not a renewal. | 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.
