EcoFlow is set to introduce its next-generation home battery system, the OCEAN 2 Plus, at Solar and Storage Live London 2026. The event will take place at ExCeL London from 29 to 30 April. The new system is designed to combine performance, scalability, and intelligent energy management, marking a notable advancement in residential energy solutions for the UK. It aims to meet current energy demands while adapting to future needs as the market shifts toward more flexible and decentralised energy models.
Scalable Design for Modern Homes
The EcoFlow OCEAN 2 Plus Single-Phase system is built with long-term flexibility in mind. A single unit can start small and expand over time, supporting up to 300 kWh of storage capacity when multiple units are configured in parallel. This allows the system to go beyond traditional residential use, accommodating larger homes with electric vehicles, heat pumps, and increasing electrification demands. With a battery lifespan of 10,000 cycles, the system is engineered to deliver consistent performance and savings over many years.
Optimised for UK Conditions
Performance has been tailored for real-world UK conditions. The system features three independent Maximum Power Point Trackers (MPPTs), which maximise solar generation across rooftops with multiple orientations or partial shading. This ensures more consistent energy capture throughout the day. Each string supports high input capacity, enabling installers to design more efficient, higher-yield systems without compromise.
Efficiency extends beyond generation. The OCEAN 2 is designed to minimise its own energy consumption, operating at just 50 watts during light-load discharge. Although often overlooked, this reduction in baseline energy use contributes to meaningful long-term savings. Estimated lifetime energy savings can reach up to 6,000 kWh over a 15-year period.
Streamlined Installation and Safety
Installation has been simplified throughout the design. The compact form factor, integrated components, and reduced on-site complexity save time at every stage, from handling and positioning to commissioning. Each battery pack weighs 46 kg and supports both indoor and outdoor installation, providing practical flexibility for installers working across a wide range of property types.
Whole-home backup functionality is built in as standard, with seamless switching designed to maintain power continuity across essential systems. This is complemented by a multi-layered safety architecture that combines passive and active protection mechanisms. A 15-year warranty further supports long-term peace of mind.
Integration with EcoFlow Ecosystem
At the system level, the OCEAN 2 integrates into EcoFlow's wider Home Energy Ecosystem, connecting solar generation, storage, and smart home technologies into a single intelligent platform. Through its Home Energy Management System, the system can automatically optimise when to store and use energy based on demand and dynamic electricity tariffs. This helps households reduce reliance on the grid while improving overall energy efficiency.
Craig Bilboe, head of residential UK, Australia and New Zealand for EcoFlow, said: “UK homes are changing quickly. We're seeing more electric vehicles, more heat pumps, and more people wanting to use their own solar more effectively. OCEAN 2 Plus Single-Phase has been built for that reality. It gives installers a system that's quicker to work with, and gives households the ability to store more, use more, and expand over time without replacing what they already have. Alongside that, technologies like STREAM are opening the door for people who want to start smaller, making solar more accessible in a way we haven't really seen in the UK before.”
Visitors to the EcoFlow stand at the exhibition will be able to experience live demonstrations of the OCEAN 2 Plus Single-Phase, explore upcoming product developments, and speak directly with EcoFlow's technical and commercial teams.
