Warranty period

10-year product warranty

The Powerwall 3 (Part Number 1707000-xx-x) is warranted free from defects for ten years from initial installation. Issued by Tesla Motors Netherlands B.V.; applies to units purchased from Tesla or a Tesla certified installer and installed in Australia.

Capacity retention: unlimited-cycle applications

Used for solar self-consumption, time-based control, or backup only (in any combination), the Powerwall 3 is warranted to retain at least 70% of its rated 13.5 kWh usable capacity at ten years: with no limit on charge/discharge cycles.

Capacity retention: all other applications

For any application or combination including a non-listed use, 70% retention at ten years applies subject to a maximum aggregate throughput of 37.8 MWh at the battery AC output: exceeding it before ten years may affect the capacity warranty.

Minimum warranty floor: internet connectivity

Internet connection and Tesla registration are required for remote firmware updates, a condition of the full ten-year warranty. Extended disconnection or non-registration may mean the full period is not honoured, but Tesla always honours a minimum of four years from initial installation, subject to all other exclusions and limitations.

What’s covered

Defects in materials and workmanship

Covers failures from defects in materials or workmanship that stop the unit operating as warranted: battery cells, integrated inverter, power electronics, and associated hardware supplied as part of the unit.

Energy capacity shortfall

Measured usable capacity below 70% of the rated 13.5 kWh before the ten-year period expires (or the 37.8 MWh throughput limit, where applicable) is a warranty event. Rated starting capacity: 13.5 kWh AC at 25°C at beginning of life.

Remedies: repair, replacement, or refund

Remedy at Tesla's sole discretion: repair, replacement with an equivalent product (possibly refurbished, same type), or refund of the market price of an equivalent product at the time of the claim. The remainder of the original period carries over to the repaired or replacement unit, subject to Australian Consumer Law rights.

Gateway and related products

The same ten-year warranty and terms apply to the Backup Gateway 2 (Part Numbers 1118431-xx-x, 1152100-xx-x), Powerwall 3 Expansion units (Part Number 1807000-xx-x), Tesla Remote Energy Meter, and Neurio Energy Meter installed as part of the system.

Australian Consumer Law

Provided in addition to, and without excluding, restricting or limiting: Australian Consumer Law rights. Non-excludable ACL guarantees include replacement or refund for a major failure and compensation for reasonably foreseeable loss or damage.

Exclusions

Labour for removal and reinstallation: Removal from the original installation site or reinstallation elsewhere is not covered, and relocation without Tesla's express written consent voids the warranty entirely.

Non-certified installation, modification, or repair: Storage, installation, commissioning, modification, repair, or opening of the external casing by anyone other than Tesla or a Tesla certified installer voids the warranty: as does any physical or software modification without Tesla's written consent.

Abuse, misuse, negligence, and force majeure: Excludes damage from abuse, misuse, negligence, accidents, or force majeure events: lightning, flood, earthquake, fire.

Failure to operate or maintain per Owner's Manual: Excludes defects or capacity shortfalls from failure to operate or maintain the unit per the Tesla Owner's Manual.

Normal wear, superficial defects, and theft: Excludes normal wear and tear, superficial dents or marks not affecting performance, non-excessive noise or vibration, damage after the period expires or is voided, and theft of the unit or its components.

Extended internet disconnection or failure to register: Extended internet disconnection or failure to register with Tesla may mean the full ten-year warranty is not honoured, a minimum four years remains. Register via the Tesla certified installer at commissioning or directly with Tesla thereafter.

Life-support and medical equipment use: Not warranted, and Tesla disclaims all liability: for primary or backup power to life-support systems, medical equipment, or any application where failure could cause injury, loss of life, or catastrophic property damage.

Transferability

Claimable by the original end user or a subsequent owner who supplies proof of ownership. Claims go through the original Tesla certified installer, or directly to Tesla if that installer is unavailable.

How to make a claim

Contact the supplying Tesla certified installer first; if unavailable, contact Tesla at PowerwallSupportANZ@tesla.com, 1800 294 431 (Australia), or via a Service Request Form at tesla.com/en_au/support/powerwall. Include proof of original purchase and any ownership transfers, a defect description, and the unit's serial number and original installation date. Obtain a Return Merchandise Authorisation (RMA) number from Tesla before returning any product.
