Why Choose Fox ESS?
Fox ESS batteries are a smart, affordable way to bring energy storage to both small and large UK homes. With modular sizing, you can start small and add more capacity later, keeping costs manageable as your energy needs grow. Their compact design saves space, while lightweight units make installation quick and simple.
Each system includes a high-performance inverter, battery pack and energy management technology in one setup. Depending on configuration, Fox ESS delivers up to 12 kW of power and can store more than 30 kWh per stack — enough for most households to run comfortably on solar.
The Little Green Energy Company now installs Fox ESS systems across Kent, Surrey and Sussex, helping homeowners unlock the benefits of clean energy without the premium price tag. With 5 kWh to 10 kWh modules, durable weatherproofing, a 10-year warranty and easy app control through FoxCloud, it’s a reliable, cost-effective choice for long-term savings.
What Is Fox ESS and How Does It Work?
Fox ESS is a complete home energy storage system, giving you control over your solar power, battery storage and daily electricity use. For households with EVs, it can also integrate with charging to maximise savings.
Your solar panels generate electricity during the day, and any unused power is stored in the Fox ESS battery for later. The system then supplies your home when you need it — cutting reliance on the grid and lowering bills.
With its smart energy management software, Fox ESS automatically chooses the most efficient way to use your energy. You don’t need to manage anything yourself — though the FoxCloud app makes it easy to monitor and adjust settings from your phone.
How Does Fox ESS Combine Solar and Battery Storage?
Fox ESS works seamlessly with your solar panels and home battery in one simple system. During the day, your home runs on solar power first, with any surplus energy stored in the battery for later use.
The system carefully manages energy flow to ensure you store as much clean electricity as possible, reducing your reliance on the grid. This not only cuts bills but also protects you from rising energy prices.
Thanks to its efficient charging and discharging design, Fox ESS minimises energy loss, so you get the most value out of every unit of solar your panels produce.

Smart Energy Management and Simple App Control
The Fox ESS system uses intelligent energy management to learn how your household consumes power. It looks at your usage patterns, solar forecasts, and grid prices to decide when to store, use, or draw electricity — always aiming to save you money.
With the FoxCloud app, you can easily check battery levels, track solar production, and even schedule charging times. Everything is displayed in clear, simple terms, so you’re always in control without needing technical know-how.
Fox ESS makes smart energy simple, giving you peace of mind and more value from every unit of electricity.
Modular Design, Safety and Flexible Growth
Storage Options
Fox ESS batteries are built to grow with your home. Start with a single module and add more as your needs change. Each unit typically stores between 5 kWh and 10 kWh, giving you the flexibility to size your system for today and expand it tomorrow.
You can link multiple modules together for up to 30–60 kWh of storage, depending on your setup. The system can be installed indoors or outdoors, with robust weatherproofing to keep it safe year-round.
Safety First
Fox ESS systems come with multiple built-in safety protections. These include advanced temperature monitoring, short-circuit protection, and overcharge prevention to keep your battery secure in all conditions. Homeowners can trust that their system is designed for long-term reliability and safe operation.
Mixing Old and New Batteries
One of the benefits of Fox ESS is its ability to work with both new and existing battery modules. This means you can expand or upgrade your system without replacing the whole setup — making it a cost-effective and future-proof choice for UK households.
Fast Installation, Warranty and Long-Term Value
Easy Installation
Fox ESS systems are designed for quick, hassle-free installation. The modular units connect neatly without complex wiring, and the system is up and running fast — with most installations completed in less than a day.
Warranty
Every Fox ESS battery comes with a 10-year warranty, guaranteeing at least 70% capacity after a decade of use. For extra peace of mind, extended cover options are also available, ensuring your investment is protected long into the future.
Flexible Options to Match Your Home
Whether you want to start with a smaller system for everyday savings or build towards greater energy independence, Fox ESS offers the flexibility to match your household. Its modular design makes it simple to expand your storage capacity over time, giving you long-term value without unnecessary upfront costs.
