The assessment
How it scores, by category
Market position
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
- Phase
- Three phase
- 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 evidencechange in the site menu
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.
Sources & references · checked 2026-09-01
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 revision. 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.
