Fox ESS: Flexible, Modular & Future-Proof Storage

At Nebula Renewable Ltd, we know that no two UK homes are the same. That is why we specialise in Fox ESS modular energy storage. Unlike rigid "all-in-one" systems, Fox ESS gives you the ultimate flexibility by separating the high-performance hybrid inverter from the high-voltage battery units (such as the EP, ECS, or EQ ranges).

This modular approach means we can tailor the installation to your specific property layout, ensuring you get the most efficient performance possible while leaving the door wide open for future upgrades.

The Fox ESS Advantage: Designed to Adapt

1. Bespoke Installation Flexibility

Because the inverter and batteries are separate units, they don’t have to be bolted together in one bulky stack. This allows Nebula Renewable Ltd to optimise your home layout—for example, placing the inverter in a utility room while the batteries are tucked away in a garage or cupboard. It is the perfect solution for homes where space is at a premium.

2. Intelligent Real-Time Communication

Although the units are separate, they act as one "brain." Using Fox’s proprietary high-speed communication, the inverter and battery constantly exchange data. This ensures the system responds instantly to your home’s energy demands, solar generation, and smart tariff schedules, delivering maximum efficiency and protection at all times.

3. Scalable "Energy Cube" Technology

Your energy needs today might not be the same in three years. With Fox ESS, scaling up is simple. You can start with a smaller battery capacity and easily add more high-voltage modules later. It’s a truly future-proof investment that grows alongside your family or business.

4. Engineered for the UK Grid

Fox ESS systems are designed to work seamlessly with the UK’s evolving energy market. They integrate perfectly with smart energy tariffs, allowing you to automate your charging and discharging to ensure you are always using the cheapest electricity available.
