In Sunbridge’s eyes
Consumer-tech pedigree, now in fixed storage
EcoFlow built its name on portable power stations , founded in 2017 by ex-DJI battery engineers in Shenzhen, and now backed by HongShan (formerly Sequoia China). PowerOcean is its move into fixed home storage, and it has landed in Australia CEC-approved, LFP, and carrying a 15-year warranty that outruns most of the field.
- Modular LFP that scales from 5.1 up to 45 kWh.
- 15-year warranty (70% capacity retained after 6,000 cycles) , beats the standard 10.
- Hybrid inverter and battery in one system, so there’s no separate inverter to spec.
- App and monitoring carry EcoFlow’s consumer-tech polish.

FAQ
Frequently asked questions
It is EcoFlow’s newest single-phase home battery , an all-in-one system pairing a 6–12 kW single-phase hybrid inverter with stackable 5 kWh and 8 kWh OCEAN 2 LFP packs, for up to 96 kWh on a single inverter.
Up to 12 battery packs on a single inverter , using the new 8 kWh packs, that is up to 96 kWh. Cascading up to 5 inverters raises the ceiling to around 480 kWh for large homes.
Both are OCEAN 2 LFP packs at 100% depth of discharge. The 5 kWh pack is 5.02 kWh (2.5 kW charge / 3.4 kW discharge); the new 8 kWh pack is 8.03 kWh (4.1 kW charge and discharge), so it adds more capacity and power per pack.
Yes. It provides integrated whole-home backup with a seamless 0 ms switchover, so it can keep essential circuits , or the whole home , running during an outage. Sunbridge configures the backup to your switchboard.
Through the EcoFlow app, the web portal and the PowerInsight tablet, with real-time visibility of solar generation, storage, consumption and backup status, plus time-of-use automation to trim your bill.
