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.

DE Warranty scope

- Germany; the exact X1-MINI G4 family is current on SolaX's German product surface. Serial-specific coverage and the applicable German warranty instrument remain controlling.
- After
- Germany; the exact X1-MINI G4 family is current on SolaX's German product surface. SolaX's German warranty page lists the German-language document 2026 Garantiebestimmungen und Bedingungen EU DE V1.7 202609 (listed 23 September 2026). For products installed on or after 15 September 2026 in the European Union, Scotland, Norway and Switzerland, its Table 1 names X1-MINI G4 & G4 PLUS with a 5-year standard warranty from the earlier of first installation or 9 months after manufacture, extended free of charge to 10 years when the inverter is connected to SolaX Cloud and generation data is uploaded; the series name includes X1-MINI-3.3K-G4. Earlier sales or installations follow the previous version. Serial-specific coverage and the applicable German warranty instrument remain controlling.
Value
- Before
- All eight exact queued configurations are listed in the reviewed AU CEC inverter event source through 25 September 2026. The prior recorded expiry was 11 August 2026.
- After
- All eight exact queued configurations are listed in the reviewed AU CEC inverter event source through 25 September 2026 as checked on 13 August 2026. The later Clean Energy Regulator inverter export (last modified 24 September 2026, captured 29 September 2026) lists the same eight configurations with expiry 25 October 2026, which supersedes the September expiry. The prior recorded expiry was 11 August 2026.
DE Support Note
- Before
- SolaX's German product page names the X1-MINI G4 family across 0.6 kW to 4.0 kW. This outcome resolves the exact 3.3 kW scored identity and does not carry Australian approval evidence into Germany.
- After
- SolaX's German product page names the X1-MINI G4 family across 0.6 kW to 3.3 kW, nine bins (0.6, 0.7, 0.8, 1.1, 1.5, 2, 2.5, 3 and 3.3 kW). This outcome resolves the exact 3.3 kW scored identity and does not carry Australian approval evidence into Germany.

- The current CER approved-inverter export checked 4 October 2026 lists the eight exact X1-MINI G4 AS4777-2 2020 configurations under SolaX Power Network Technology (Zhe jiang) Co Ltd, approved 13 May 2023 and expiring 25 October 2026. No renewal beyond that date is established.

- The cited Australian page names scored X1-MINI-3.3K-G4. The manufacturer family also publishes a 0.8 kW bin, which is excluded because the current full CER export contains no exact Australian approval row for that code. On 4 October 2026 the eight accepted exact configurations expire 25 October 2026, correcting the earlier September wording. Renewal beyond 25 October remains unverified. This approval-only review does not refresh manufacturer-page, warranty or whole-market verification dates.
