| Certifications | The German store page names IQBATTERY-5P-3P-INT. The INT datasheet lists EN IEC 62109-1/-2, AS IEC 62619, UN 38.3 and UL 9540A evaluation. | EcoFlow's exact German OCEAN 2 three-phase datasheet lists IEC/EN 62619, IEC/EN 62040-1, IEC/EN 62477-1, ISO 13849-1, VDE-AR-E 2510-50, EN IEC 61000-6-1/-2/-3/-4 and UN 38.3 for battery module EF BD-5-S2. |
| Warranty scope | Germany; the 25 October 2024 German IQ Battery 5P with FlexPhase instrument names IQBATTERY-5P-3P-INT for the earlier of 15 years or the published capacity schedule, with 70 percent at year 10 and 60 percent at year 15. | EcoFlow's current German product surface publishes a 15-year warranty for the OCEAN 2 three-phase hybrid inverter and 5.02 kWh LFP battery module. The duration headline does not establish every remedy or service entitlement. |
| Warranty remedy | Enphase may repair, replace or provide a depreciated market-value refund. | The exact remedy remains governed by EcoFlow's applicable home-solar warranty instrument. |
| Labour and reinstallation | Uninstall, reinstall and ordinary site labour are not limited-warranty entitlements. Removal and reinstallation are not included in the limited warranty. | No unconditional full-term owner-selected labour entitlement was established from the duration headline. No unconditional removal and reinstallation entitlement was established from the duration headline. |
| Freight | Eligible RMA return and repaired or replacement-product shipping are covered under the published process. | No unconditional full-term freight entitlement was established from the duration headline. |
| Transfer and registration | Same-site transfer requires the owner-change form and fee within 30 days. Activation, registration within 45 days, authorised supply and continuous IQ Gateway connectivity apply. | An automatic later-owner transfer right was not established from the reviewed German product and support surfaces. The applicable warranty instrument and installer commissioning requirements remain controlling. |
| Grid/network approval evidence | AC-coupled storage. The reviewed INT datasheet prints grid compliance as AS/NZS 4777.2. That is not a standalone German grid-interconnection claim. Site inverter and network approval remain installation-specific. No product pairing is asserted. | Current German three-phase OCEAN 2. EcoFlow qualifies the published 0 ms transfer by local grid compliance, open-circuit state, load within rated backup output and stable grid conditions. |

| Review note | Enphase's German store lists IQ Battery 5P with FlexPhase as IQBATTERY-5P-3P-INT. The North American IQBATTERY-5P-1P-NA record is not this identity. | The exact three-phase OCEAN 2 is offered through EcoFlow's German quote route, and EcoFlow publishes a German service hotline and European support address. Battery-passport readiness is not inferred from present product availability. |
