CES 261 kWh modular battery storage system

The CES 125 kW / 261 kWh is a high-performance battery storage system for businesses that wish to actively manage their energy consumption and make the most of their own energy from renewable sources. This battery storage system combines high performance, modularity, a compact design and intelligent energy flow management. It helps to reduce electricity costs, increase energy independence and prepare operations for future market demands.

Why choose a FENIX battery storage system?

You’ll gain full control over your company’s energy management
The battery offers high performance in a minimal space
The modular storage system can be easily expanded to up to six units
Development, manufacturing and operational data management all take place in the Czech Republic
It features liquid cooling for stable performance
The battery’s long service life ensures a long-term return on investment
The storage system is designed for safe, continuous operation

Full control over the company’s energy management

The CES battery storage system, with a capacity of 261 kWh and an output of 125 kW, allows you to store energy from your own sources and use it when it suits you best.

Thanks to intelligent charging and discharging management, the battery manages energy based on forecasts of consumption, generation and electricity prices. Energy thus becomes an actively managed part of the company’s finances, rather than merely an operating cost.

High performance in a compact space

Measuring just 1,050 × 1,360 × 2,400 mm, the CES occupies approximately 1.5 m² of floor space. Thanks to its high energy density, it is also ideally suited to facilities where space is at a premium. Its compact design simplifies the installation of battery storage systems in industrial sites, logistics centres and office buildings.

The modular system allows up to six Battery units to be connected

A business’s energy requirements evolve over time. The CES battery therefore allows for easy expansion by up to five additional battery units, bringing the total to six interconnected storage units. Both the output and capacity of the storage system can be increased gradually in line with the businesses’ actual needs, without having to change the basic design of the energy system.

Development, production and the management of operational data all take place in the Czech Republic

The CES battery is part of a solution that we, as part of the FENIX Group, develop and manufacture directly in the Czech Republic. This means you gain not only battery storage, but also a system designed for the conditions of the Czech energy sector, direct technical support and readily available servicing. Another key component of the solution is control over operational data and energy information, which remains under the management of a trusted partner. The result is greater security, transparency and long-term independence from foreign platforms and suppliers.

Liquid cooling for consistent performance

Active liquid cooling ensures uniform temperature conditions for all battery cells and reliable battery operation within a temperature range of -25 °C to +55 °C. Cooling contributes to higher system efficiency, reduces cell degradation and helps maintain stable performance even under prolonged load.

Long service life for a long-term return on investment

The battery storage system uses modern LFP 314 Ah cells, which allow for a depth of discharge of up to 100 per cent and have a stated service life of at least 8,000 cycles. The battery therefore utilises the stored energy to the full and offers predictable long-term operating costs.

What sort of site preparation is required for a battery storage system?

The system is usually installed on pre-prepared concrete footings or strip foundations, rising to a height of approximately 30 cm above the surrounding ground level. Earthing strips are also laid as standard during the preparation of the foundations. Depending on the orientation of the equipment, protective conduits containing the appropriate cabling are also routed to the connection point.

The detailed design of the site preparation must always be discussed in advance; where applicable, the design is specified in the project documentation. When selecting the location for the battery storage facility, we assess not only the specified clearance distances but also the accessibility for transport and handling equipment.
