| Certifications | The current Australian regulator snapshot lists GW3K, GW3.6K, GW5K, GW6K, GW8K and GW9.999K EHA-G20 under the ESA family through 25 July 2028., GW10K-EHA-G20 appears on the broader manufacturer sheet but is not included in this Australian record because it is absent from the current local approval snapshot. | The current CER snapshot lists M8, M9 and M10, approved 7 July 2026 and expiring 7 July 2029. |
| Warranty scope | Australia and New Zealand; the governing ESA warranty explicitly names GW3K-EHA-G20, GW3.6K-EHA-G20, GW5K-EHA-G20, GW6K-EHA-G20, GW8K-EHA-G20 and GW9.999K-EHA-G20 for ten years. | Australia; the exact SMILE-M-S inverter warranty provides ten years for the named M8, M9 and M10 family. |
| Warranty remedy | GoodWe may change configuration or software, repair with parts, or replace with a new, refurbished or functionally equivalent product. | AlphaESS may repair, replace or otherwise settle an accepted claim under the governing terms. |
| Labour and reinstallation | Any on-site labour rebate is offered only in some areas or business cases at GoodWe's sole discretion. Removal and reinstallation are not promised as an unconditional owner 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| Freight | Normal ground transport may be covered in some areas up to an unpublished limit; excess and alternate transport remain with the claimant. | Replacement-part freight is covered within the stated process; broader transport is not unconditional. |
| Transfer and registration | No general subsequent-owner transfer right was located in the reviewed voluntary warranty. Claims require original-purchase evidence, exact serial identity and notice within one month after the fault appears. | 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 hybrid power-module family with current AS/NZS 4777.2 regulator entries. DNSP settings, export limits and final site design remain installation-specific. | The exact model or family appears in the current Australian approved-inverter export. DNSP settings, export limits and site design remain installation-specific. |

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.
