| Certifications | IEC 61000-6-1/-6-3, IEC 62477-1, IEC 62109-1/-2, IEC 62933-5-2, IEC 62619, UL 1973, UL 9540A and AS/NZS 4777.2 on Tesla's Australia/New Zealand Powerwall 3 datasheet. | The 29 July 2026 CER exports list ten exact FlexPhase power and phase identities through 31 December 2027., The exact AU/NZ datasheet lists AS/NZS 4777.2:2020 + A2, AS IEC 62040.1, EN IEC 62109-1/-2, AS IEC 62619, and UN 38.3, and states UL 9540A evaluation. |
| Warranty scope | Australia and New Zealand; Tesla Motors Netherlands B.V. provides ten years and 70% of 13.5 kWh for solar self-consumption, time-based control and backup with unlimited cycles. Other or mixed applications are capped at 37.8 MWh measured at the battery AC output. | Australia and New Zealand; Enphase Energy, Inc. provides the earlier-of 15-year or 6,000-cycle warranty, with 70% capacity at year 10 and 60% at year 15. |
| Warranty remedy | Repair, equivalent replacement or market-price refund at Tesla's option. | Repair, replacement, or depreciated purchase-price refund under the governing terms. |
| Labour and reinstallation | The voluntary warranty does not promise a general labour reimbursement entitlement. Removal and reinstallation costs are not expressly promised; relocation requires Tesla's written consent. | Removal, reinstallation, and electrical troubleshooting labour are not unconditional limited-warranty entitlements. Not included in the limited warranty; a separate capped installer reimbursement program has its own eligibility conditions. |
| Freight | An RMA is required and no unconditional owner freight reimbursement is stated. | Eligible RMA return and repaired or replacement-product shipping are covered under the published process. |
| Transfer and registration | A subsequent owner may claim with proof of ownership; Tesla's Australian registration workflow provides an Initiate Transfer process in the Tesla app. Unapproved relocation from the original site can void cover. Registration and extended internet connectivity are required for the full term; cover may reduce to at least four years if they are not maintained. | Conditional same-site transfer with form and fee within 30 days. Activation, authorised supply, and the governing registration and connectivity conditions apply. |
| Grid/network approval evidence | The exact Australian identity is single-phase 230 V and is listed at 5, 10 and 11.04 kVA with Backup Gateway 2. The installed maximum-output setting must be marked on the product label and, once confirmed, can only be changed through Tesla Support. At a three-phase site the gateway can accept three-phase feed-in, but Powerwall 3 remains a single-phase source and site backup scope is installation-specific. | The exact family supports commissioned single-phase or three-phase operation. Regulator listing does not establish site, network, islanding, or installation approval. |

| Review note | Claims start with the selling Tesla Certified Installer or Tesla's direct service route. Tesla Motors Australia Pty Ltd is active locally, while the voluntary warranty names Tesla Motors Netherlands B.V. as provider. | Enphase Energy Aust. Pty/Ltd. is the named Australian importer. The Australian product page publishes local store and telephone support. |
| Register: parts term | stated: Ten-year product warranty. | stated: Fifteen years from activation or the warranty start defined by the instrument, subject to the earlier cycle limit. |
| Register: labour and service | not stated: The instrument does not state a general entitlement to installer labour, removal or reinstallation costs. | excluded: Removal, installation and troubleshooting of the surrounding electrical system are not included in the limited warranty. |
| Register: transport and freight | not stated: The instrument does not state a general entitlement to transport or freight costs for a claim. | conditional: Enphase supplies a prepaid eligible return label and ships an eligible repaired or replacement product. Unapproved returns and shipping damage are excluded. |
| Register: registration | conditional: Powerwall must be registered with Tesla and connected to the internet for the full warranty term. If internet connectivity is not maintained, Tesla requires at least four years of connection in aggregate, subject to the instrument. | conditional: Activation and authorised supply conditions apply. Continuous internet should be maintained for software updates and remote diagnostics. |
| Register: transferability | stated: A subsequent owner may claim with proof of lawful transfer, but relocation without prior written approval is excluded. | conditional: Transfer is limited to the same original installation location and requires the form and fee within 30 days. |

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.
Define the usable energy, output power, backed-up circuits and outage behaviour. Confirm whether VPP participation, an internet connection, or an additional controller changes the configuration, reserve level, warranty or support path.
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.
