What the documents establish
Published evidence, source-reviewed non-disclosure and unresolved questions remain separate from the product score.
Warranty coverage: 5-year term
Coverage includes
Parts only · term longer than 0 of 95 scored inverters
No inverter in the fleet publishes a year-by-year performance or output guarantee the way panels and batteries do - this shows the covered term against the market-typical term and where every scored inverter’s term lands (grey dots, sized by model count), plus what the warranty actually includes.

Global benchmark. This scorecard is benchmarked globally. A global score does not imply local availability, certification, warranty coverage, or installer compatibility.
Benchmark anchor. The score is anchored to the highest published output in the exact Australian series. Scored model: GW6K-DNS-G40 · checked 2026-07-31. Evidence.

Strong evidence coverage
22 of 22 scored criteria link directly to a published source.
Values marked estimated, derived, or not found remain visible on the audit sheet and do not carry the same evidential weight as a linked source. Coverage measures direct links, not an independent guarantee that a claim is correct.

Rings, outside in: manufacturer claim, certified or regulator-listed, third-party source. The centre is review.solar's own measurement, empty for every product today. Warranty terms and design facts that rest on the maker's own word are counted beside the rings; a reviewed absence, or one that reaches beyond the maker's claim, stays in them.

AU Warranty scope
- Before
- Australia and New Zealand; GoodWe's current terms name DNS G4 under five years of limited inverter cover, with applicable extensions subject to the published conditions.
- After
- GoodWe Technologies Co., Ltd. Rev 5.9, dated 17 September 2026, names DNS G4 for five years of AU/NZ limited cover. The period starts at first installation or 12 months after production, whichever is earlier. The ten-year all-on-grid promotion requires manufacture after 1 July 2020 and installation, registration and SEMS connection after 1 January 2021. The separate five-year spare-parts extension names DNS and DNS G3, not DNS G4. Authorised supply and the supplied unit's governing terms remain controlling.
AU Warranty conditions
- Current text
- labour: GoodWe may arrange a paid on-site engineer or offer a discretionary service rebate. A rebate requires prior site-visit authorisation, the rebate being claimed by the party performing the service, return and confirmation of a workmanship/material defect, and a claim within two months of authorisation. The amount requires confirmation with GoodWe. This is conditional support, not an unconditional owner-selected labour entitlement; promotional-year scope remains unestablished.; registration: For the ten-year promotion, meet the stated manufacture, installation, registration and SEMS-connection dates. Claim within one month of failure through the supplying distributor or installer, escalating to GoodWe's service-ticket channel if needed. Provide model/serial, installation and failure dates, fault and prior-action details, claimant and site information. Confirm the RMA before exchange and submit its report within one month of the determined solution. The terms also warn that failure to provide a remote firmware-upgrade path can affect warranty coverage; no allowed offline interval is specified.; remedy: At GoodWe's choice: configuration or software correction, spare-parts repair, or a new or refurbished replacement that is at least functionally equivalent. Replacement retains the original remaining term, extended to one year if less remains. Obtain RMA confirmation before exchange. Return the defective product within four weeks after receiving its replacement; a late return or no confirmed damage can result in charges for the replacement, delivery and associated service. Excluded claims may incur handling charges. Australian Consumer Law rights remain additional.; removal reinstallation: Removal and reinstallation are not an unconditional entitlement.; transferability: No subsequent-owner transfer right was found in the governing terms.; transport: Normal inbound and outbound ground freight is covered up to GoodWe's per-case rate, which must be confirmed. Excess charges and other transport methods are the claimant's responsibility. Return packaging and the four-week return deadline apply; non-return or no confirmed defect can trigger replacement, delivery and service charges. Promotional-year freight scope remains unestablished.
