Market context
Global evidencechange in the site menu
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 Plus (single-phase hybrid inverter + 5.02 kWh nominal LFP modules, expandable to 96 kWh) · checked 2026-08-23. Evidence.
Sources & references · checked 2026-08-23
Strong evidence coverage
17 of 17 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.
Record revision. EcoFlow OCEAN 2 exact Australian product documents, LFP manual and battery warranty V1.4 valid 15 August 2026, rechecked 2026-08-23.

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.
