Introducing the PowerOcean Three-Phase Kit: The Future of Home Energy Storage

EcoFlow, a portable power and eco-friendly energy solutions company, proudly introduces the PowerOcean Three-Phase Kit with three 5kWh LFP Battery, 10kW Inverter, Battery Junction Box and Battery Base (15kWh/10kW PowerOcean Kit), a new battery storage system that prioritises safety above all else. Tailored for homeowners in the UK, the Three-Phase comes after the successful launch of the Three-Phase model across European markets last year.

Engineered with cutting-edge technology and a relentless focus on protecting homes and families, the PowerOcean Three-Phase sets a new benchmark for secure and dependable energy storage.

This innovative system ensures homeowners enjoy unmatched efficiency and performance, providing peace of mind and uninterrupted power supply, even during unexpected outages or emergencies.

The price includes a basic set of cables, protection disconnectors, and accessories required to create a fully operational system. User manuals and a connection diagram will be supplied with your order. Mounting not included - if you require a mounting system, select a suitable option here or contact us for advice.

The system must be installed by a licensed electrician or solar installer in compliance with all applicable regulations and guidance. For residential dwellings, guidance here must be followed.

  • Unmatched Battery Safety and Reliability: Each battery unit surpasses industry safety standards, ensuring families receive top-tier protection. Compliance with the new PAS 63100:2024 guidelines is a cornerstone of PowerOcean, meeting essential safety, fire resistance, and mechanical impact criteria for both inverters and batteries.

This achievement is made possible through advanced Lithium Iron Phosphate (LFP) battery technology and the integration of cutting-edge safety features. Among them, a fire prevention module actively addresses fire-related anomalies before they escalate. EcoFlow guarantees every homeowner can rely on the security and dependability of their energy storage solution.

The IP65-certified aluminium casing provides sturdy protection against environmental elements, facilitating safe outdoor installations. Each battery pack includes built-in heating pads that adjust automatically to maintain optimal operating temperatures, ensuring consistent performance in extreme weather conditions.

  • Seamless Integration: The PowerOcean Three-Phase seamlessly integrates with other power system components. Equipped with a built-in DC-DC converter, each 800V high-voltage pack can function independently, maintaining efficiency even with a single 5kWh battery pack. Additionally, PowerOcean's paralleled connection battery technology enables effortless expansion of battery capacity to 15kWh, ensuring adaptability to changing energy requirements without compromising safety.

    In times of crisis, the PowerOcean hybrid inverter delivers up to 10kW of backup power, ensuring critical appliances such as oven or borehole water pump remain operational during unforeseen power outages. Users benefit from real-time monitoring and control via the intuitive EcoFlow app and Web Portal, as well as EcoFlow’s PowerInsight, a 10-inch touchscreen home energy management system providing visibility and control over power usage, solar input, and battery storage.

  • Effortless Installation and After-Sales Support: The PowerOcean Three-Phase offers a hassle-free installation process with a simple three-step commissioning process and a wiring-free stack-up battery design, enabling homeowners and installers to expand and install the system effortlessly.

    With the EcoFlow Pro app dedicated to installers, device status can be monitored effortlessly, and PowerOcean error codes are intelligently categorized by their emergency level, streamlining the troubleshooting process.

    Rest assured, PowerOcean is backed by comprehensive after-sales support, providing prompt service, maintenance, and assistance throughout the product's lifespan.
