About EcoFlow

Modular home energy storage with intelligent control

EcoFlow brings modular battery storage, whole-home backup and smart app control together for households that want flexible, expandable energy storage.

EcoFlow focuses on modular home energy storage, offering high-voltage battery systems and integrated backup. Its approach is designed to support households that want to expand capacity over time while keeping installation and monitoring simple.

  • 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

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.
Best suited to

homeowners wanting expandable capacity and a long warranty from a fast-moving consumer-tech brand — less proven in Australian installed storage than the established inverter names.

EcoFlow PowerOcean Three-phase · with Sunbridge

The right fit for your home — and fully backed

Why the PowerOcean Three-phase fits your home

Modular, expandable homes

Each pack has a built-in DC-DC converter, so you start from 5.1 kWh and expand to 45.9 kWh whenever you like.

Efficient high-voltage design

800 V high-voltage architecture means lower current for the same power, reducing losses across the system.

Three-phase backup

Up to 12 kW of three-phase backup keeps a large home running through an outage.

Smart app control

The EcoFlow app gives real-time visibility of solar generation, storage, backup status and savings.

ACLAustralian Consumer Law protected
Warranty & compliance
  • The EcoFlow PowerOcean battery (EF BD-5.1-S1 and the matching stacks) is covered by EcoFlow’s PowerOcean Home Solar Battery Solutions Limited Warranty for Australia and New Zealand, issued by EcoFlow Australia Pty Ltd.
  • EcoFlow guarantees a minimum of 70% of the battery’s nominal capacity after 15 years or 6,000 cycles, whichever comes first, from the installation date. The warranty also sets out separate cover periods for the inverter and other components.
  • These are the manufacturer’s terms; your guarantees under the Australian Consumer Law apply in addition. Sunbridge confirms the warranty terms that apply to your configuration and registers the warranty on your behalf as part of the installation.
Rebates & payback guidance
  • Home battery storage can be eligible for government rebates and incentives, which change over time and vary by state and household. A correctly sized PowerOcean system — paired with the right rebate — can meaningfully shorten your payback period.
  • Sunbridge handles rebate guidance as part of the quote process: we check current eligibility, factor available incentives into your system design, and show you the expected payback based on your actual usage. See our battery rebate guidance for more, and we will confirm what applies to your address when you request a quote.
