| Certifications | IEC 62933-5-2:2020, IEC 62619:2022 and UN 38.3 are listed for the exact Powerwall 3P. | 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; ten years and 80% retained capacity, subject to registration, internet connectivity and use-profile conditions. | 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 | Tesla may repair with new or refurbished parts, replace with an equivalent product, or refund equivalent market value. | The exact remedy remains governed by EcoFlow's applicable home-solar warranty instrument. |
| Labour and reinstallation | The written warranty does not expressly allocate site labour. Unconditional removal and reinstallation coverage is not stated. | 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 | The written warranty does not expressly allocate ordinary freight. | No unconditional full-term freight entitlement was established from the duration headline. |
| Transfer and registration | A later owner can claim with proof of ownership; relocation requires Tesla's written consent. Registration and reliable internet are required for the full ten-year term; non-registration or extended disconnection can reduce coverage to four years. | 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 | The listed IEC battery and system-safety credentials do not by themselves establish universal connection under VDE-AR-N 4105. The exact three-phase configuration and site settings remain subject to installer and network approval. | 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. |

| Buyer evidence | Ready (100% direct coverage): Local availability, buyer evidence, and the publication threshold are confirmed. | Ready (100% direct coverage): Local availability, buyer evidence, and the publication threshold are confirmed. |

| Review note | Powerwall 3P is a distinct German three-phase identity. It is not the Australian single-phase Powerwall 3 record, and the Expansion is a separate model. | 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. |
