What the documents establish
Published evidence, source-reviewed non-disclosure and unresolved questions remain separate from the product score.
Warranty coverage: 12-year term
Coverage includes
Parts only · term longer than 85 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.

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: X1-MINI-3.3K-G4 · checked 2026-09-04. Evidence.
Sources & references · checked 2026-09-04
Strong evidence coverage
18 of 18 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.

AU Support Note
- Current text
- The live Australian page still names X1-MINI-3.3K-G4. The current manufacturer family also publishes X1-MINI-0.8K-G4, which remains absent from the current CER export and is deliberately excluded. The listing still expires on 25 September 2026. This is a freshness recheck, not a renewal.

US Support Note

- SolaX USA's product catalogue lists A1-HYBRID G2, A1-AC and A1-MICRO. It does not list X1-MINI-3.3K-G4 as a United States SKU. A 2023 global news post on the US hostname is not a United States sale path. A1-Hybrid G2, A1-MICRO, X1-HYBRID G4 and the German 0.6-4.0 kW range are not transferred onto scored Australian 3.3K.
