About EcoFlow
What is the EcoFlow PowerOcean?
An EcoFlow home battery is a modular system. One hybrid inverter connects your solar panels, the grid and a stack of LFP battery packs. You start with a few packs and can add more later, up to the limit of the inverter. EcoFlow sells two pack generations in Australia: the PowerOcean LFP pack (5.1 kWh, 4.8 kWh usable) and the newer OCEAN 2 LFP packs (5.02 kWh and 8.03 kWh).
What we quote depends on your supply. Single-phase homes get the OCEAN 2 Plus Single-Phase inverter (EF HD-P1-8K0-S2A at 8 kW, or EF HD-P1-9K9-S2A at 9.999 kW) with PowerOcean packs (EF BD-5.1-S1). EcoFlow says OCEAN 2 can be combined with earlier PowerOcean packs. Three-phase homes get the 10 kW PowerOcean Three-Phase inverter (EF HD-P3-10K-S1) with PowerOcean packs. The other three-phase option uses OCEAN 2 8 kWh packs (EF BD-8-S2A). These go on the 12 kW OCEAN 2 Three-Phase inverter (EF HD-P3-12K0-S2F) or the 15 kW PowerOcean Plus Three-Phase inverter (EF HD-P3-15K0-S1).
EcoFlow was started in 2017 by a group of battery engineers. Its datasheets list China as the country of manufacture. On 15 October 2026, all five inverter models we quote and the PowerOcean pack were on the Clean Energy Council approved product lists.
High-voltage architecture
Modular high-voltage battery systems are designed to work with a matched hybrid inverter and backup.
Expandable capacity
Battery capacity can be scaled by adding modules as household energy needs grow.
Smart app control
The EcoFlow app supports real-time monitoring of generation, storage and backup status.

In Sunbridge’s eyes
EcoFlow review: an installer’s view
EcoFlow built its name on portable power stations; its About page says it was started in 2017 by a group of battery engineers. PowerOcean and OCEAN 2 are its fixed home storage range. The Clean Energy Council first approved the PowerOcean pack in November 2025, and EcoFlow lists 15 years of warranty on the PowerOcean and OCEAN 2 inverters and on the PowerOcean and OCEAN 2 5 kWh packs (10 years, extendable by 5, on the OCEAN 2 8 kWh pack).
- Modular LFP packs , up to 45.9 kWh on the PowerOcean three-phase inverter and up to 12 modules on OCEAN 2 inverters.
- 15-year PowerOcean pack warranty (70% after 15 years or 6,000 cycles); 10 + 5 years on the OCEAN 2 8 kWh pack.
- Hybrid inverter and battery in one system, so there’s no separate inverter to spec.
- App and monitoring carry EcoFlow’s consumer-tech polish.

What size EcoFlow battery do I need?
Start with the energy your home uses between sunset and sunrise. Your retailer bill, smart meter data or solar app shows it in kWh. Choose a battery whose usable capacity covers that, plus any growth you expect from an EV or electric hot water. The site inspection confirms the size before you commit.
Our EcoFlow packages run from 15.3 to 32 kWh. Single-phase: 3, 4 or 6 PowerOcean packs (15.3, 20.4 or 30.6 kWh) on an 8 kW or 9.999 kW OCEAN 2 Plus inverter. We count 4.8 kWh usable per pack, which gives 14.4, 19.2 or 28.8 kWh usable. That inverter takes up to 12 battery modules. Three-phase: 4 or 5 PowerOcean packs (20.4 or 25.5 kWh, with 19.2 or 24 kWh usable) on the 10 kW PowerOcean inverter, which supports up to 45.9 kWh. The other option is OCEAN 2 8 kWh packs, rated 8.03 kWh usable each. We fit 3 or 4 of them (24 or 32 kWh) on the 12 kW OCEAN 2 inverter, which takes up to 12 modules. We also fit 3 on the 15 kW PowerOcean Plus, which EcoFlow rates to 60 kWh per inverter. A floor stack holds up to 4 PowerOcean packs, and EcoFlow asks installers to check local rules before stacking more than 4 OCEAN 2 packs. Wall mounting is limited to 3 packs. Our 5 and 6 pack PowerOcean systems therefore use two stacks.

Can I add a EcoFlow battery to my existing solar?
Yes, EcoFlow supports both paths. Every inverter we quote is a hybrid, so new panels connect straight to it. Already have a working solar inverter? EcoFlow says its OCEAN 2 inverters can connect a third-party solar inverter on the backup side. That means the old system may not need replacing. We confirm the right set-up at inspection.
- New panels: OCEAN 2 inverters have 3 MPPTs and a 120 V start-up voltage. Rated PV input is up to 16 kW on the 8 kW single-phase model and 20 kW on the 9.999 kW model. The 12 kW three-phase model takes up to 24 kW.
- The 10 kW PowerOcean Three-Phase inverter takes up to 14 kW of PV across 2 MPPTs. The 15 kW PowerOcean Plus takes up to 30 kW across up to 4 strings.
- Keeping your inverter: EcoFlow states that OCEAN 2 inverters accept a third-party solar inverter on the backup side, so a working system can stay in place.
- Match the phase: a single-phase supply needs the single-phase inverter, and a three-phase supply needs a three-phase model. We quote both.
- Old equipment: removing an old inverter or battery is a separate option on our quote, so you see the cost before you book.
What does the EcoFlow price include, and what costs extra?

EcoFlow PowerOcean and OCEAN 2 pros and cons
What we tell customers before they choose EcoFlow.
Pros
- Modular. Start with 3 packs and add more later, up to the limit of your inverter.
- LFP (lithium iron phosphate) cells in every pack, rated IP65 (PowerOcean) or IP66 (OCEAN 2) for indoor or outdoor installation.
- OCEAN 2 8 kWh packs are rated 8.03 kWh usable at 100% depth of discharge (EcoFlow test conditions, start of life), with 4.1 kW nominal charge and discharge.
- OCEAN 2 inverters have 3 MPPTs, which EcoFlow designed for roofs with several orientations.
- Mixed generations. Each PowerOcean pack has its own DC-DC converter, and EcoFlow says OCEAN 2 works with earlier PowerOcean packs, so packs added later can run alongside older ones.
- Monitoring through the EcoFlow app, the EcoFlow web portal or the PowerInsight 2 display.
Cons and things to check
- PowerOcean packs hold back 5%. Each 5.1 kWh pack gives 4.8 kWh usable at 95% depth of discharge, so usable capacity is below the headline size.
- Warranty differs by pack. EcoFlow lists 15 years for the PowerOcean and OCEAN 2 5 kWh packs. The OCEAN 2 8 kWh pack has 10 years standard, with an optional 5-year extension.
- EcoFlow datasheets note that power may be derated above 40 °C, so a shaded, ventilated spot matters.
- The packs are heavy: 55.5 kg for PowerOcean and 67.5 kg for the OCEAN 2 8 kWh pack. A floor stack holds up to 4 PowerOcean packs, so 5 and 6 pack systems need a second stack and more wall space.
- EcoFlow is new to Australian home storage. The Clean Energy Council first approved the PowerOcean pack in November 2025. The OCEAN 2 inverters followed in July and September 2026, so the local track record is short.

FAQ
Frequently asked questions
They are two generations of the same modular design. PowerOcean packs are 5.1 kWh, with 4.8 kWh usable at 95% depth of discharge. OCEAN 2 packs come in 5.02 kWh and 8.03 kWh and are rated fully usable at the start of life. OCEAN 2 inverters also add a third MPPT, and EcoFlow says the two generations can be combined.
It depends on your supply and the size you choose. Single-phase quotes use the OCEAN 2 Plus Single-Phase inverter with PowerOcean packs. Three-phase quotes use the PowerOcean Three-Phase inverter with PowerOcean packs, or OCEAN 2 8 kWh packs on an OCEAN 2 or PowerOcean Plus inverter. Every model number is listed on your quote.
EcoFlow rates PowerOcean cells for at least 6,000 cycles before capacity falls to 70%, and 3,500 cycles to 80%, at 25 °C. It rates OCEAN 2 cells for 10,000 cycles. EcoFlow lists a 15-year warranty for PowerOcean and OCEAN 2 5 kWh packs, and 10 years for the OCEAN 2 8 kWh pack with an optional 5-year extension. Real life depends on temperature and how often the battery cycles.
Yes. PowerOcean and OCEAN 2 packs use lithium iron phosphate (LiFePO4, or LFP) cells, which are a type of lithium-ion. Each pack has its own battery management system. EcoFlow also lists a built-in fire prevention module in both pack types.
