The data
All-in-one energy system
Presents storage and power conversion as one integrated product or product platform.
- Product role
- Battery modules, inverter functions and controls are packaged as one purchasing architecture.
- Published range
- 13.5 kWh

- Backup boundary
- Installation-specific
Capacity guarantee: minimum retained at year 10
No year-by-year capacity schedule is published for this product - the manufacturer guarantees only this end-of-term minimum, not a specific decline curve. Capacity figure based on the sourced usable capacity of the base configuration; modular systems scale with additional modules.

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 uses the named exact German benchmark; larger stacks, paid states and nearby generations do not transfer evidence. Scored model: Powerwall 3P 1988000-xx-y · checked 2026-08-16. Evidence.

Strong evidence coverage
8 of 8 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.

Record correction. Powerwall 3P German datasheet and warranty effective 19 March 2026, checked 2026-08-16. First-market US overlay review 2026-09-01: official United States catalogues recorded; existing Australian and German overlays and scores unchanged. Correction 2026-10-08: operating temperature corrected from the wide, heat-optimised band to the standard band, and warranty throughput corrected to unlimited cycles for standard solar use, from the German warranty and datasheet.

DE Certifications
- Before
- IEC 62933-5-2:2020, IEC 62619:2022 and UN 38.3 are listed for the exact Powerwall 3P.
- After
- IEC 62933-5-2:2020, IEC 62619:2022 and UN 38.3 are listed for the exact Powerwall 3P.; The exact Powerwall 3P datasheet also lists VDE-AR-N 4105:2018-11 with Correction 1:2020-10, VDE V 0124-100:2020-06, IEC 62477-1:2022, IEC 62109-1:2010 and IEC 62109-2:2011, and the Radio Equipment Directive 2014/53/EU, under its certificates (page 3).
DE Grid and installation context
- Current text
- The exact datasheet lists VDE-AR-N 4105:2018-11 with Correction 1:2020-10 and VDE V 0124-100:2020-06 as certificates and states an output power factor of -1 to 1 with grid-connection rules configurable. It does not publish the certificate documents, issuing body, certified power bins or firmware conditions, and a listing does not by itself establish connection at a given site. The exact three-phase configuration and site settings remain subject to installer and network approval.

DE Warranty scope
- Before
- Germany; ten years and 80% retained capacity, subject to registration, internet connectivity and use-profile conditions.
- After
- Germany; Tesla Motors Netherlands B.V. warranty Rev. 1.15, effective 19 March 2026, explicitly covers Powerwall 3P 1988000-xx-x bought from Tesla or a Tesla-certified installer and installed within the listed European warranty region. Ten years from first installation and 80% of 13.5 kWh nominal capacity; self-consumption, time-based control and backup have unlimited cycles. Other uses, or mixed uses including an unlisted use, have a 37.8 MWh cumulative AC-output limit. Listed uses do not establish feature availability for every configuration. Registration and connectivity conditions apply; the German appendix preserves additional statutory rights. The applicable purchaser instrument remains to be confirmed.
DE Warranty conditions
- Current text
- labour: The written warranty does not expressly allocate site labour.; registration: Full ten-year cover requires registration and ongoing internet access for remote firmware updates, which may briefly interrupt operation. Customers who did not buy directly from Tesla or an affiliate should register through commissioning or later contact; prolonged disconnection or non-registration can reduce cover, but the instrument guarantees at least four years from first installation under its stated exclusions. Claims go first to the selling Tesla-certified installer; direct Tesla contact applies for direct purchases or an unreachable seller. Supply original purchase and subsequent ownership evidence, suspected defect, serial number and original installation date; request a Tesla RMA through the service form before returning a product. No fixed claim-notification day count is stated.; remedy: Subject to applicable local law, Tesla chooses repair with new or refurbished parts, equivalent new or refurbished replacement, or the market value of an equivalent product at claim time. Repair or replacement keeps the remainder of the original warranty term, unless local law requires otherwise. The German appendix preserves separate statutory rights. Site cost allocation remains unresolved.; removal reinstallation: Unconditional removal and reinstallation coverage is not stated.; transferability: The original purchasing/commissioning end user and a later owner with ownership evidence can claim; the claim package includes original purchase and subsequent ownership transfers. Relocation from the original installation site requires Tesla written consent. Ownership transfer does not by itself permit relocation or restart the warranty.; transport: The written warranty does not expressly allocate ordinary freight.
