Global benchmark. This scorecard is benchmarked globally. A global score does not imply local availability, certification, warranty coverage, or installer compatibility.

Benchmark anchor. Capacity range describes supported configurations; the score remains anchored to the reviewed reference configuration, not the largest stack. Scored model: EcoFlow Ocean 2 (three-phase hybrid inverter + 5 kWh LFP battery modules, stackable to 60 kWh) · checked 2026-08-23. Evidence.

Strong evidence coverage

18 of 18 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.

    Current text
    EcoFlow does not sell Ocean 2 in the United States: its United States product page returns not found, and EcoFlow's own sitemap carries the Ocean 2 page for Australia, Germany, Spain, Europe, France, Italy, the Netherlands, Poland, Sweden, the United Kingdom and Georgia with no United States entry. No three-phase counterpart exists either. EcoFlow's United States inverter datasheet publishes a 208Y/120 V three-wire connection taken from a three-phase four-wire service, which is a United States commercial service arrangement and not the 400 V three-phase supply this record is scored against, and every EcoFlow entry on the California Energy Commission lists is 208 V or 240 V. The United States equivalent class is served by the later OCEAN Pro platform, EF-PCS-24 with EF-BP-10 batteries. EcoFlow Technology Inc issues the United States warranty and states it is valid only on products purchased and used in the United States, from 2020 Main St, Irvine, CA 92614.

    The exact three-phase AU product page, rendered on 7 October 2026, shows no 'Coming Soon' label and offers a Free Quote enquiry form for houseowners and business partners. An enquiry form does not establish stock, a launch date or a consumer purchase and installation path, which remain unestablished. The governing policy routes claims through an authorised installer first and then EcoFlow support. App, web-portal and PowerInsight management are published. The AU catalogue-linked OCEAN 2 three-phase user manual V1.1 (23 September 2026), page 13, publishes 15 years of software support for EF HD-P3-5K0/6K0/8K0/10K0/12K0-S2 and S2F hybrid inverters. It does not specify the support-period commencement or a calendar end date, guarantee cloud-service lifetime or offline monitoring, or establish a software-support term for the EF BD-5-S2 battery module.

    Current text
    labour: The battery policy does not state an owner entitlement to site labour, removal or reinstallation; no labour cover is inferred.; registration: Clause 1.3: the warranty starts automatically on the earlier of commissioning (activation) or nine months after the production date, and no additional manual registration is required. Clause 1.10: the product must remain connected to the internet; if disconnected for over one year, coverage adjusts to five years from the original activation date.; remedy: EcoFlow may provide online assistance, factory repair, refurbishment or replacement for an accepted claim.; removal reinstallation: No unrestricted removal and reinstallation entitlement is stated.; transferability: Clause 1 of V1.4 allows transfer from the original owner to the next owner only while the product is still installed at its initial location and has not been moved. No new-owner registration step is stated.; transport: Materials, accessories and approved logistics for an accepted claim are borne by EcoFlow, subject to the policy process.

    AU Warranty conditions

    Current text
    labour: The battery policy does not state an owner entitlement to site labour, removal or reinstallation; no labour cover is inferred.; registration: The system must remain connected to the internet. More than one year disconnected reduces the warranty to five years; same-site transfer also requires new-owner registration.; remedy: EcoFlow may provide online assistance, factory repair, refurbishment or replacement for an accepted claim.; removal reinstallation: No unrestricted removal and reinstallation entitlement is stated.; transferability: Transfer to the next owner is conditional on the product remaining at its initial installation address and the new owner registering it with EcoFlow.; transport: Materials, accessories and approved logistics for an accepted claim are borne by EcoFlow, subject to the policy process.
