What the documents establish
Published evidence, source-reviewed non-disclosure and unresolved questions remain separate from the product score.
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.

Market context
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 and displayed range remain inside the exact source and market boundary recorded by the 13 August 2026 sprint. Scored model: T-BAT H 23 V2 · checked 2026-08-29. Evidence.
Sources & references · checked 2026-09-01
Strong evidence coverage
12 of 12 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.

- Germany; no German battery warranty naming T-BAT H 23 V2 was attached, so six-field terms are not transferred from the Australian SolaX instrument.
DE Support Note
- Before
- Not previously recorded
- After
- de.solaxpower.com lists the four V2 configurations including T-BAT H 23 V2. TSYS-HS51 and T-BAT HS46.8 are different identities and are not merged here. Manufacturer listing is established; distributor inventory is not inferred. The Australian CER expiry of 22 September 2026 stays on the preserved AU overlay and is not restated as a German fact.
