What the documents establish
Published evidence, source-reviewed non-disclosure and unresolved questions remain separate from the product score.
Warranty coverage: 25-year term
Coverage includes
Parts only · term longer than 90 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.

Strong evidence coverage
15 of 15 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. Exact technical and warranty sources plus CER source version dated 20 August 2026, checked 2026-08-27. First-market US and DE overlay review 2026-08-30: official regional catalogues recorded; Australian overlays and scores unchanged. Inverter operating-envelope refresh 2026-08-31: remaining peak, weighted, oversizing or thermal gaps closed as scoped reviewed absences.

AU Warranty scope
- Before
- Australia and New Zealand; the current instrument explicitly includes IQ9N-A-INT for a 25-year product term.
- After
- Australian/New Zealand LGL-00031 v4.0 explicitly names IQ9N-A-INT for 25 years from Activation Date: the earlier of registration or activation at the original location through the Installer Portal, with activation linked to permission to operate. This instrument applies to activation on or after 30 September 2025 unless a newer warranty governs that activation date. Purchase must be from Enphase or an authorised reseller. Enphase Energy, Inc. is the warrantor; the Australian service entity is separate. Australian Consumer Law guarantees remain additional.
AU Warranty conditions
- Current text
- labour: Uninstall, reinstall and ordinary site labour are excluded.; registration: Submit claims during the warranty period and within 30 days of discovering the defect, following the Australian RMA process. Unless Enphase instructs otherwise, return the defective product in original or equally protective packaging within 60 days of the RMA number; otherwise the owner is charged the then-current replacement list price. The RMA process provides a prepaid return label. Clause 6(c)(viii) requires registration and microinverter internet connection through an Envoy within 45 consecutive days following Warranty Start Date, then continuous connection; the IQ9 term separately uses Activation Date and that trigger difference remains unresolved. Clause 3 allows interruptions outside the owner’s reasonable control. No US first-installation trigger or numeric offline allowance is transferred, and a warranty connectivity condition does not establish that ordinary PV conversion requires cloud access.; remedy: Enphase chooses repair or replacement with new or reconditioned parts/products of original or improved design, or purchase-price refund less reasonable depreciation. A refund is selected only when replacement is unavailable and repair impracticable or untimely, or the owner accepts it. Replacement or repair retains the original remaining term or 90 days from receipt, whichever is later; it does not restart 25 years. Refund is processed within two weeks of Enphase receiving the product. Eligible shipping of the repaired or replacement product to the original site is covered; non-covered or unauthorised returns may be rejected or returned at the owner’s cost, or held for 30 days before disposal. Troubleshooting, removal and reinstallation labour are excluded from this limited warranty; statutory consumer guarantees remain additional.; removal reinstallation: Removal and reinstallation are excluded.; transferability: Coverage can pass to a subsequent owner only while the product remains at its original installation site. The new owner must submit the change-of-ownership form and pay the applicable transfer fee within 30 days of transfer; the fee may change. The clause also references registration requirements through inconsistent section numbering, which remains a drafting ambiguity rather than an unconditional transfer promise.; transport: Eligible product freight is conditional on the approved claim process.

AU Support Note
- Before
- The source sheet is marked preliminary. The score uses only values explicitly published for IQ9N-A-INT and does not convert the 560 W recommended module ceiling into a DC:AC oversizing claim.
- After
- Exact source DSH-00859-3.0-EN-2026-07-13 is released, with Australia/New Zealand scope. Grid-compliance row requires IQ Relay; some advanced grid functions require IQ Gateway Metered/CTs and/or IQ Relay. This bounded sheet review does not refresh the regulator listing or market availability. The560W row and STC/clipping footnote do not establish a finite scored DC:AC ceiling.

- labour: Uninstall, reinstall and ordinary site labour are not limited-warranty entitlements.; registration: Covered SKUs must match the German schedule. Continuous internet connectivity is required except for interruptions outside the owner's reasonable control.; remedy: Enphase may repair, replace or provide a depreciated market-value refund.; removal reinstallation: Removal and reinstallation are excluded from the limited warranty.; transferability: Same-site transfer requires the owner-change form and fee within 30 days.; transport: Eligible RMA return freight uses Enphase's prepaid label. Enphase pays shipment of the repaired or replacement product after an accepted claim.

DE Support Note
- Before
- Not previously recorded
- After
- Enphase's German store lists IQ9N-A-INT. IQ9N-A-DOM-US is a different SKU and is not this record. The INT sheet remains the specification source; distributor stock is not inferred.
US Support Note
- Before
- Not previously recorded
- After
- Enphase's United States store page for IQ9N Microinverter names SKU IQ9N-A-DOM-US. The IQ9 series page also names IQ9N-3P-277-A-US. Neither is IQ9N-A-INT. IQ9N-A-INT is not treated as a US counterpart part.

DE Grid and installation context
- Before

- The reviewed IQ9N-A-INT sheet prints grid compliance as AS/NZS 4777.2 and does not print VDE-AR-N 4105. German connection approval remains installation-specific.
