Next-generation safety
and seamless scalability

The EcoFlow PowerOcean combines a highly efficient hybrid inverter with advanced modular LFP batteries. Featuring internal DC-DC optimisers and active fire protection, it's designed for ultimate peace of mind and effortless expansion.

☀️

High-Efficiency Inverter

Available in 3.68kW, 5kW, or 6kW single-phase options. Features a wide 90V-520V MPPT range to ensure maximum solar energy capture, even in low-light conditions or typical UK weather.

🔋

Built-in DC-DC Converter

Every 5kWh battery module has its own independent DC-DC converter. This means you can start with just one 5kWh battery and add new batteries years later without performance drops or mixing issues.

🛡️

Active Fire Protection

Safety comes first. Each battery pack integrates an active aerosol fire prevention module that detects thermal anomalies and mitigates hazards instantly at the cell level, plus auto-heating pads for sub-zero winters.

🧠

Octopus Energy API Integration

Manage your entire system via the award-winning EcoFlow App. Full API integration allows the system to pair effortlessly with Octopus Agile and Flux tariffs to automatically buy cheap energy and sell high.

Common questions about
the EcoFlow PowerOcean

Want to know if the PowerOcean is right for your home? Call us on 01482 426674 or send us a message.

The EcoFlow PowerOcean stands out through its incredible 15-year warranty, active cell-level fire extinguishing modules built directly into the batteries, and internal DC-DC converters.
