| Certifications | 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. | The German H1 G2 datasheet V2.0 names H1-6.0-E-G2 and prints EN 62109-1/-2, EN 50549-1, C10/11, VDE-AR-N 4105, G98, G99 and CEI 0-21. |
| Warranty scope | Germany; the 30 September 2025 German microinverter schedule explicitly lists IQ9N-A-INT for a 25-year product term from activation. | Germany; the 4 December 2025 German inverter instrument names Hybrid-Serie at 60 months. It does not name H1-6.0-E-G2, so six-field terms are not attached from that instrument or from the Australian 120-month table. |
| Warranty remedy | Enphase may repair, replace or provide a depreciated market-value refund. | Not established |

| Grid/network approval evidence | 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. | Single-phase 220/230/240 V hybrid family. The German G2 sheet prints VDE-AR-N 4105. DNSP and site settings remain installation-specific. |

| Review note | 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. | de.fox-ess.com lists H1/AC1 3-6 kW and the German G2 datasheet names H1-6.0-E-G2. KH 7-10.5 kW is a different family. Manufacturer listing is established; distributor inventory is not inferred. |
