| Certifications | Sungrow's German SH15/20/25T product page names SH15T, SH20T and SH25T. The German SH5.0-25T manual identifies VDE-AR-N 4105 among applicable grid standards for that family. | The German store page names SKU IQ9N-A-INT and 427 VA. The IQ9N-A-INT sheet lists EN IEC 62109-1/-2 safety and CE labelling. |
| Warranty scope | Germany; Sungrow's German service factsheet publishes 10 years for inverters up to 20 kW and 5 years above 20 kW. The scored SH25T is above 20 kW, so the 5-year term applies. That 5-year term is not transferred onto SH15T or SH20T, and the 10-year band is not transferred onto SH25T. The governing German warranty terms remain controlling. | Germany; the 30 September 2025 German microinverter schedule explicitly lists IQ9N-A-INT for a 25-year product term from activation. |
| Warranty remedy | Sungrow may repair or replace an accepted defective product under the governing terms. | Enphase may repair, replace or provide a depreciated market-value refund. |
| Labour and reinstallation | Removal, installation and reinstallation labour are excluded unless a separate written service arrangement applies. Removal and reinstallation are not unconditionally covered. | Uninstall, reinstall and ordinary site labour are not limited-warranty entitlements. Removal and reinstallation are excluded from the limited warranty. |
| Freight | The claimant pays freight to Sungrow; Sungrow pays delivery of the repaired or replacement product under the reviewed terms. | Eligible RMA return freight uses Enphase's prepaid label. Enphase pays shipment of the repaired or replacement product after an accepted claim. |
| Transfer and registration | Transfer at the same installation site requires Sungrow's agreement under the reviewed German terms. Proof of purchase, product identity and performance data requested for diagnosis remain claim conditions. | Same-site transfer requires the owner-change form and fee within 30 days. Covered SKUs must match the German schedule. Continuous internet connectivity is required except for interruptions outside the owner's reasonable control. |
| Grid/network approval evidence | Current German three-phase hybrid SH15T, SH20T and SH25T family. Grid-profile selection, export settings and final connection approval remain installation-specific. | 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. |

| Review note | Sungrow's German residential catalogue names SH15/20/25T. SH5T and SH10T are a different scored family even though they share the SH5.0-25T German manual. The broader manual does not make every family member interchangeable. | 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. |
