| Certifications | The current Australian approved-inverter list names SH5T and SH10T as three-phase multiple-mode PV and battery inverters under certificate SGS/230890, approved 14 August 2024 and expiring 14 August 2027., The exact datasheet lists AS/NZS 4777.2:2020, IEC/EN 62109, EN 50549-1, VDE-AR-N 4105 and further national grid standards. | The Australian CEC approved-inverter export dated 22 July 2026 lists exact GW6000-ET-20, GW8000-ET-20, GW9900-ET-20, GW12K-ET-20 and GW15K-ET-20 models to AS/NZS 4777.2:2020 through 29 October 2027., The exact system manual lists IEC 62109-1/-2 and multiple national grid codes. |
| Warranty scope | Sungrow Australia's Version 4.2 standard warranty explicitly names SH5T and SH10T for a 10-year term. The standard remedy includes repair or replacement, standard freight and a published service rebate rather than an unlimited promise to meet every site cost. | Australia and New Zealand; GoodWe's current Rev 5.8 limited warranty explicitly places ET G2 under 10 years of cover for eligible products. |
| Warranty remedy | Repair or replacement at Sungrow's discretion for an approved claim. | Configuration change, repair or replacement at GoodWe's discretion. |
| Labour and reinstallation | The standard service rebate contributes to approved replacement labour but does not promise all site costs. The service rebate contributes to replacement work; full removal and reinstallation cost is not unconditional. | GoodWe may provide authorised on-site service or a conditional service rebate. On-site labour support is conditional and requires prior authorisation. |
| Freight | Standard freight is covered within the governing warranty limits. | Normal ground transport is covered up to GoodWe's stated case limit. |
| Transfer and registration | The remaining warranty transfers when original purchase evidence is available. Optional parts-only or standard-warranty extensions are governed by the separate published extension terms. | No express subsequent-owner transfer right was found in the governing terms. The standard ET G2 term is listed as 10 years; claim and monitoring conditions in the governing terms still apply. |
| Grid compatibility | Three-phase 220/380 V, 230/400 V or 240/415 V hybrid family with exact Australian approved-list entries. DNSP settings, export limits and phase-balance requirements remain installation-specific. | Three-phase 380/400 V hybrid family with exact-model CEC listings. DNSP acceptance, export settings, battery pairing and backup design remain installation-specific. |

| Review note | Only SH5T and SH10T are included. The broader manual also names SH6T, SH8T and SH12T, but those models are excluded because they were not present in the current Australian approved-inverter result checked for this migration. | The 15 kW GW15K-ET-20 is the scored series benchmark. CEC listings are dynamic and should be checked before installation. |

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.
