- Official AU product page retrieved 2026-09-26 names X1-FIT G4 and X1-FIT-3.7-W / 4.6-W / 5.0-W / 6.0-W / 7.5-W. The AU sitemap lists loc x1-retro-fit.html. Guessed x1-fit-g4.html and x1-fit.html 404 are not this loc. The 3.7-W through 7.5-W tabs are parameter columns of this family, not extra identities. Meta 3.7kW, 4.6kW, 5kW, 6kW, and 7.5kW matches those tabs and is not an extra identity. Body copy that prints X1-FIT G4 is this identity. Adjacent AU x3-retro-fit.html is X3 FIT G4, not this identity. Adjacent AU x3-hybrid-g4.html is X3-HYBRID G4, not this identity. Adjacent AU x3-hyb-g4-pro.html is scored X3-HYB-G4 Pro, not this identity.
- Guessed datasheet paths solax-x1-fit-g4-datasheet-en-au.pdf, solax-x1-fit-g4-datasheet-en.pdf, and solax-x1-retro-fit-datasheet-en-au.pdf returned 404 and are not invented as a datasheet.
- The manufacturer string is taken from AU warranty PDF V1.6, which names this family as its own 10 year row X1-fit-3.0/3.7/5.0/6.0/7.5 -W G4. That legal name is not copied from a Declaration of Conformity onto a product the Declaration does not name. The separate X1-fit I/E 10 year row is not transferred. The X3-fit E/C and X3-fit -W G4 rows are not transferred. The X3-Hybrid D G4, X3-Hybrid N, X3-HYB-P Pro, and X1-Hybrid-D G4 rows are not transferred. Warranty 3.0-W on the G4 row is not invented as an AU page tab. AU page 4.6-W is not dropped because that warranty row omits it.
- The same X1-fit-3.0/3.7/5.0/6.0/7.5 -W G4 string appears on the live AU warranty table for 10 years. Adjacent I/E, X3-fit, Hybrid D G4 / N, Pro P, and X1-Hybrid-D G4 rows are not transferred.
- Official global product page returns 200, h1 X1-FIT G4, with the same W tabs. Global sitemap lists that loc. The global products path redirects to our-products with the same body hash and is not a second identity. Guessed US products and our-products paths 404 are not overlay rewrites. Official German products and our-products paths 200 titled X1-FIT G4 are not overlay rewrites. German nav that also prints adjacent families is not this identity.
- The AU downloads index HTML retrieved 2026-09-26 contains X1-FIT G4 as a downloads filter label and does not contain a static href to an X1-FIT G4 datasheet PDF. Loc x1-retro-fit is not printed on that downloads index. Adjacent nav card X3 FIT G4 linking to /products/x3-retro-fit.html is X3 FIT G4, not this identity.
- CER inverter pin au-cer-inverter-2026-09-11-dfb0c0c3d4b0 names zero X1-FIT-*-W / X1-Fit -W G4 rows. Named X1-Fit I/E rows on the same pin are not transferred. AU overlay availability is not invented. The CER state file is not rewritten. CER manufacturer spelling is not copied.
- Datasheet was not retrieved. Page does not print TP-HS50E or TBMS-MCS0800E. Those codes stay composition of the host inverter records that print them and are not invented onto this retrofit inverter. Leftover T-BAT HS JSON is not restamped. Parallel support up to 150kW is not a pairing.
