| Certifications | TUV Rheinland Australia certificate of suitability AZ 69028757, published by GoodWe Australia, lists GW3K-DNS-G40, GW3.6K-DNS-G40, GW4.2K-DNS-G40, GW5K-DNS-G40 and GW6K-DNS-G40 against AS/NZS 4777.2:2020 + Amd 1:2021 + Amd 2:2024, IEC 62109-1:2010 and IEC 62109-2:2011, issued 27 October 2025 and expiring 27 October 2030. The Clean Energy Regulator approved inverter list shows the same five DNS G4 codes, including GW6K-DNS-G40 (AS4777-2 2020), approved on 27 April 2026 with expiry on 27 April 2029 (list file dated 24 September 2026). | The CER approved inverter list, last modified 2 October 2026 and read on 7 October 2026, lists exact H3-Pro-15.0 (AS4777-2 2020) at 15 kW, approved 21 January 2026 and expiring 21 January 2029., The current Australian datasheet and manual identify H3-Pro-15.0 as a three-phase storage inverter. |
| Warranty scope | 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. | The Australian and New Zealand warranty policy, Version 4.0 dated 1 April 2026, expressly names H3-Pro-15.0. The standard term is 120 months from installation, capped at 132 months after manufacture. Conditional service-rebate and transport provisions do not establish unrestricted labour or freight cover. |
| Warranty 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. | FoxESS may repair onsite or at a service centre, or replace with the closest current product. |
| Labour and reinstallation | 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. Removal and reinstallation are not an unconditional entitlement. | An installer service rebate may be approved, but its amount and eligible work are not stated; travel, onsite installation, modification and maintenance are excluded. Unrestricted removal and reinstallation cover is not stated. |
| Freight | 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. | Eligible road transport to one specified address may be provided; express and onward shipping are excluded. |
| Transfer and registration | No subsequent-owner transfer right was found in the governing terms. 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. | No automatic subsequent-owner transfer right is stated. Version 4.0 prints no separate registration section. The FoxPlus clause applies if the product is registered on the FoxESS website within 36 months of manufacture, and cross-refers to section 8, which in this version is the claim process. No registration condition is stated for the 120-month standard term. |
| Grid/network approval evidence | Single-phase 230 V Australian string-inverter family with AS/NZS 4777.2 compliance. | Three-phase Australian identity. CER product listing does not establish DNSP, site, export-limit, installation or commissioning approval. |

| Register: parts term | conditional: DNS G4 has a five-year base limited warranty. A ten-year promotional term applies to on-grid models manufactured after 1 July 2020 when installed, registered and connected to SEMS after 1 January 2021. DNS G4 is not named in the separate automatic five-year spare-parts extension list for DNS, DNS G3, MS and MS G3. | stated: The exact H3-Pro family receives 120 months from installation, no later than 132 months after manufacture, whichever occurs first. |
| Register: labour and service | conditional: GoodWe may arrange company-paid engineers or offer a discretionary service rebate after prior authorisation and confirmation of a covered defect. No fixed rate is printed. | conditional: FoxESS may repair onsite or at a service centre, replace the product, and approve an installer service rebate. The rebate amount and eligible work are not stated, while travel, onsite installation, modification and maintenance are excluded. |
| Register: transport and freight | conditional: Normal outbound and inbound ground transport is covered up to a per-case amount available from GoodWe. Excess and alternate transport remain with the claimant, and return timing and packaging conditions apply. | conditional: Eligible road transport to one specified address may be provided. Express freight and onward shipping are excluded. |
| Register: registration | conditional: The five-year base term does not state a pre-registration condition. The ten-year on-grid promotion requires eligible manufacture timing plus installation, registration and SEMS connection. GoodWe also warns that warranty may not apply when remote firmware access is withheld. | conditional: Registration is recommended for the standard term and required for FoxPlus. The policy's FoxPlus wording also refers to a 72-month standard period, which conflicts with the exact 120-month H3-Pro table. |
| Register: transferability | not stated: The governing instrument states how remaining cover transfers to a replacement unit but does not state an automatic transfer right to a subsequent owner. | not stated: The policy defines purchaser, installer and end-user roles but does not state an automatic subsequent-owner transfer right. |

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.
