SOLAR BATTERY STORAGE

True all-in-one design. The ESA Series integrates the hybrid inverter, LFP battery stack, backup switching and battery enclosure into a single pre-wired unit. This reduces installation time, minimises wiring and delivers a cleaner, more compact setup compared to traditional multi-box systems. Installation can be completed in as little as 10 minutes.

Flexible capacity and power options. Available in six inverter sizes from 3 kW to 10 kW, the ESA pairs with 5 kWh and 8 kWh battery modules that can be freely mixed within a single stack. Systems scale from 5 kWh up to 48 kWh, with up to six modules per stack and multiple stacks connectable in parallel, making it easy to start small and expand as your energy needs grow.

UPS-level backup without a gateway. In the event of a power cut, the ESA switches to backup mode in under 4 milliseconds, fast enough to keep lights, Wi-Fi routers and sensitive electronics running without interruption. Full house backup up to 63A is built in with no additional gateway required.

Safe, long-life LFP battery chemistry. The ESA uses Lithium Iron Phosphate (LiFePO₄) cells, which offer superior thermal stability and a longer cycle life compared to conventional lithium-ion alternatives. A six-layer safety system, including aerosol fire suppression and AI-driven AFCI 3.0 arc fault detection, provides comprehensive protection.

Silent, maintenance-free operation With fanless convection cooling and a noise level below 30 dB, the ESA is quieter than a whisper. There are no moving parts to wear out, making it virtually maintenance-free throughout its lifespan.

Built for UK conditions. Rated IP66 for full weather protection, the ESA can be installed indoors or outdoors. Optional integrated heating elements allow the system to operate reliably in temperatures as low as -18°C, ensuring consistent performance through British winters.

Smart monitoring via the SEMS app GoodWe’s Smart Energy Management System (SEMS) gives homeowners and installers real-time visibility of energy flows, battery status and system performance, all from a smartphone. Remote diagnostics and firmware updates keep the system running at its best.

The Duracell energy storage solar battery works seamlessly with solar panels, or as a standalone battery storage system. During the day, it stores excess energy generated by your solar panels for use at night or during cloudy periods. Alternatively, it can be used without solar to drawing low-cost electricity from the grid during off-peak hours and store it for later use during peak periods. You can also integrate other renewable sources like wind and hydro power to further enhance your home’s energy independence.

The Dura5 Solar Battery – A Smart, Sustainable Choice

The Dura5 enables homeowners to reduce energy bills significantly by storing energy for use when the system isn’t producing any solar power. The Duracell Energy App uses a smart algorithm which has been developed by Duracell Energy in the UK. It considers weather forecasts and predicts when solar capability is at its lowest, it then uses this information to ensure your battery is fully charged ready for when you need it, cutting your energy costs by an average of 90% and reducing reliance upon the grid.

The Dura5 Solar Battery offers a sustainable, affordable home battery storage solution backed by Duracell’s trusted brand. Whether you’re pairing it with solar panels, using it independently, or integrating it with wind or hydro energy sources, the Dura5 provides you with the flexibility, reliability, and savings you need to achieve energy independence.

With the ability to charge and discharge in just one hour, the Dura5 provides market-leading charge and discharge speed allowing rapid access to stored energy during high-demand periods, making it a crucial part of your energy management system.

Longer lasting & flexible installation choices: Market leading life of 8000 cycles to maximise your investment. Install wall mounted or stacked to suit your needs.

Faster charging solution for all conditions: The Dura5 keeps your home powered with market leading charge & discharge times (twice as fast as leading solar battery brands). The Dura5 operates at temperatures of up to -10C (without internal heaters reducing battery lifecycle), meaning your house won’t get snapped by the cold.

Exceptional safety by design

PowerOcean uses lithium iron phosphate (LFP) battery chemistry, which is inherently more stable and significantly safer than conventional lithium-ion battery types. Each battery module is monitored in real time by a multi-layer battery management system (BMS) that continuously tracks voltage, current, temperature and state of charge, helping to prevent over-charging, over-discharging and abnormal operating conditions.

The system includes advanced thermal protection and fault detection, allowing abnormal temperatures and operating conditions to be detected at an early stage and the system to respond automatically to protect both the batteries and the home.

PowerOcean also features electrical protection at both battery and inverter level, including protection against short circuit, over-current, over-voltage and reverse polarity. These layered protections significantly reduce the risk of electrical faults and help ensure long-term operational safety.

For installation flexibility and external mounting, the system is housed in a robust enclosure with a high ingress protection rating, providing protection against dust and water and supporting safe outdoor installation where required.

15 Year Long-term reliability backed by extended warranties

EcoFlow PowerOcean is designed for long service life and comes with strong manufacturer warranty of 15 years.
The battery modules are supplied with a long-term performance warranty, and the PowerOcean inverter is covered by a separate product warranty, giving homeowners confidence that their investment is protected for the long term.

Scalable capacity to grow with your home

The modular design of PowerOcean allows battery capacity to be expanded easily as household energy usage increases or as electric vehicles and heat pumps are added in the future. Additional battery modules can be stacked into the system without replacing existing hardware, making the system both future-proof and cost-effective.
