| Certifications | The Australian approved-inverter export lists all seven exact MIN TL-XH2 models from 2.5 kW to 6.0 kW under Shenzhen Growatt New Energy Co Ltd, with approval dated 10 July 2024 and expiry dated 10 July 2027., Growatt publishes an exact-family AS/NZS 4777 certificate and the exact datasheet lists IEC 62109 and multiple national grid codes. | 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 | The exact datasheet publishes a 10-year warranty. Growatt's Australian warranty card names MIN2500-6000TL-XH2, is non-transferable, leaves the remedy to Growatt, and limits logistics and labour responsibility after year five. | 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, on-site repair or equivalent replacement at Growatt's option. | Configuration change, repair or replacement at GoodWe's discretion. |
| Labour and reinstallation | Growatt does not accept responsibility for labour costs after year five. Removal, installation and reinstallation costs are not an unconditional warranty entitlement. | GoodWe may provide authorised on-site service or a conditional service rebate. On-site labour support is conditional and requires prior authorisation. |
| Freight | Growatt does not accept responsibility for logistics costs after year five. | Normal ground transport is covered up to GoodWe's stated case limit. |
| Transfer and registration | The governing warranty card states that coverage is non-transferable. Paid extensions to 15 or 20 years must be purchased within two years from delivery. | 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 | Single-phase 230 V Australian hybrid family with exact-model approved-inverter entries. DNSP settings, export limits and installation acceptance remain site-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 | The exact datasheet establishes compatibility only with the APX S0 Battery System from 5 kWh to 30 kWh. It does not establish APX S2 compatibility. Backup output requires a separate Backup Box; no backup capability, transfer time, surge or islanding score is claimed in this record. | 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.
