What the documents establish
Published evidence, source-reviewed non-disclosure and unresolved questions remain separate from the product score.
Warranty coverage: 10-year term
Coverage includes
Parts only · term longer than 24 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.

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
- Current text
- The Tesla Powerwall Warranty (Australia and New Zealand), Rev. 1.17 effective 3 September 2026, names Powerwall 3 part number 1707000-xx-x and is given by Tesla Motors Netherlands B.V. The term is 10 years from initial installation, with 70% of the 13.5 kWh rated capacity retained at 10 years: unlimited cycles for solar self-consumption or time-based control, and backup, or 37.8 MWh aggregate throughput for any other application (page 1). The integrated solar inverter is part of the Powerwall 3 system rather than a separately warrantied standalone inverter.

If the Powerwall is not registered or is not connected to the internet for an extended period, Tesla states it may not be able to honour the full ten years, and that it will always honour the warranty for at least four years from first installation, subject to the exclusions and limitations.; remedy: Repair, replacement or market-value refund at Tesla's option.; removal reinstallation: Removal and reinstallation are not expressly covered; unapproved relocation can void cover.; transferability: A subsequent owner may claim for the remaining term with proof of ownership.; transport: Unconditional freight cover is not stated.

Summary
- Before
- Not previously recorded
- After
- Home Assistant documents community support for Powerwall 3, introduced in release 2026.7. Its local polling integration requires compatible gateway access and installed firmware. It exposes aggregate power flow, charge and lifetime energy; backup-reserve control, off-grid switching and per-battery entities are unavailable through that route. The separate Tesla Fleet integration uses the cloud and requires developer application setup, account authorisation and energy-product permissions; not every entity is available. This is community software, not Tesla-maintained native smart-home support or a supported local MQTT interface. Confirm the installed configuration before relying on an automation. No specific heat-pump or EV functionality follows from this integration.

DE Warranty scope
- Before
- Not previously recorded
- After
- Germany; the Europe Powerwall warranty effective 19 March 2026 names Powerwall 3 part 1707000-xx-x. The integrated solar inverter is part of that system rather than a separately warrantied standalone inverter. German cover is ten years and 80 percent retained capacity on the named uses. The Australian 70 percent overlay on this record is not transferred.
DE Support Note
- Before
- Not previously recorded
- After
- This is the same 1707000-xx-y hardware as the battery record, configured for the German 230 V grid. It is not Powerwall 3P 1988000 and not Expansion 1807000. Tesla's German consumer Powerwall URL returned HTTP 403 from this review environment; the German datasheet and Europe warranty are the publication sources. A United States or Australian output figure is not transferred onto the German rating.
DE Certifications
- Before
- Not previously recorded

- The German Powerwall 3 datasheet names the same 1707000-xx-y integrated system and prints IEC 62109-1/-2, VDE-AR-N 4105:2018-11 and VDE 0124:2019 for the inverter section.

US Warranty scope
- Current text
- United States; Tesla Powerwall Limited Warranty (USA) revision 2.6, effective 6 May 2026, names Powerwall 3 part number 1707000-xx-x. The term is 10 years with 70% retained capacity and unlimited cycles for solar self-consumption, time-based control and backup, or 37.8 MWh aggregate throughput for other uses. Unlike the Australian terms on this record, the United States warranty reimburses reasonable labour to a Tesla Certified Installer when Tesla selects repair or replacement. The previous recorded instrument was revision 2.5 effective 13 November 2025. The Australian warranty on this record is not transferred.
