Configuration options
The AC cabin combines the transformer, PCS and high-voltage switchgear in a pre-assembled 30 ft unit. It enables fast, grid-compliant installation and forms the complete AC interface between the BESS and the medium-voltage grid.
The PCS container houses the complete power electronics for bidirectional energy conversion. With 2 × 1,290 kW PCS, it ensures reliable, grid-compliant AC/DC conversion and maximum operational stability in multi-MWh applications.
Our compact stations for BESS systems safely connect energy storage systems to the medium-voltage grid. We take care of the planning and construction, service and maintenance of medium-voltage systems, testing and commissioning of grid protection technology - all from a single source.
for the secure grid connection of industrial battery storage systems.
Investment in energy savings and independence
EPC services for industry BESS
As an EPC partner, Faber E-Tec BESS offers comprehensive solutions for industrial battery storage projects - from planning and procurement to turnkey commissioning. Our strength lies in the combination of technical expertise, project experience and reliable execution. Learn more about EPC BESS
With the AC cabin or PCS container plus transformer station, Faber E-Tec supplies a complete, VDE-compliant interface to the low and medium-voltage grid.
Thanks to its standard dimensions, the storage unit can be easily transported worldwide by lorry, container trailer or ship. The BESS is supplied pre-configured.
Faster installation
Preconfigured containers and factory-tested systems enable extremely short project runtimes, often significantly faster than conventional BESS projects.
Cost advantage through standardised EPC modules
Modular 20-ft and 30-ft containers reduce planning, assembly and engineering costs and minimise risks in the construction process.
Remote monitoring
Remote monitoring allows real-time monitoring of all system conditions including performance, temperature and battery health, at any time and from anywhere.
Modular & scalable
Our battery storage products grow with your requirements, from compact commercial solutions to large-scale megawatt systems.
Commercial
Reduce emissions
Battery storage systems enable the efficient use of renewable energies and reduce CO₂ emissions in commercial applications.
Equalise load peaks
BESS systems reduce peak loads, lower grid charges and optimise energy consumption in industry and commerce.
Energy for critical applications
Optimising the use of solar power
BESS systems store surplus PV electricity and increase the self-consumption rate for maximum economic efficiency.
Battery storage systems support fast-charging stations by providing powerful buffering and a stable energy supply during high-load operation.

Our BESS product range
Faber E-Tec offers battery storage systems for every application. From compact systems for commercial applications to large containers for industry and energy parks. Our solutions can be used flexibly and can be supplemented with suitable transformer stations if required. This provides you with complete energy infrastructures from a single source.
In addition to our battery storage solutions, we also develop and manufacture customised Compact transformer stations, which are perfectly matched to BESS systems. We therefore offer complete energy infrastructures from a single source, from the transformer station to the storage container.
What is the 5,015 kWh BESS container from Faber E-Tec suitable for?
The 5,015 kWh BESS container is ideal for industrial energy applications such as peak load management, grid stabilisation, reactive power control, energy storage from PV and wind systems and charging infrastructure. Thanks to its output of 2.5 MW, it can also be integrated into demanding supply grids.
What is the difference between the variant with AC cabin and the variant with PCS container + transformer?
The AC cabin solution combines PCS, transformer and switchgear in a single 30 ft cabin - ideal for compact installations. The PCS/transformer variant separates the modules into BESS container, PCS container and medium-voltage transformer, which is particularly suitable for large energy parks, utilities and modular multi-MWh projects.
Which cell technology is used in the 5,015 kWh container?
All 12 battery clusters are based on LFP cells (lithium iron phosphate 3.2 V / 314 Ah). LFP offers a high level of safety, a long service life, thermal stability and is ideal for continuous industrial use.
How is the system protected during operation?
The container has comprehensive protection mechanisms, including
- Aerosol fire extinguishing system,
- Explosion-proof flue gas routing,
- Emergency water sprinkler,
- Liquid cooling & dehumidification,
- BMS monitoring (cell/cluster/system),
- Temperature & humidity sensors,
- Protection class IP54.
This makes the system suitable for the toughest outdoor conditions.
How is cooling carried out in the 5,015 kWh BESS container?
The system utilises an intelligent liquid cooling system that precisely regulates the temperature of all 12 clusters. This prevents cell ageing, extends the service life and enables reliable 24/7 operation - even in warm climates.
Which mains connections and voltages are possible?
Depending on the variant, the following mains connections are possible:
- 690 V AC (low voltage, PCS output),
- 10-35 kV via transformer (variant with AC cabin),
- 10 / 20 / 30 kV via external transformer station (PCS/transformer variant).
All systems comply with VDE-AR-N 4110/4120, IEC 62619 and other international grid standards.
Can the 5,015 kWh container be scaled?
Yes, thanks to the string architecture and AC-side parallel connection, several containers can be modularly coupled to expand projects to multi-MWh level.
What performance does the system actually deliver?
The container delivers up to 2.5 MW discharge power at 0.5 C rate.
In combination with the AC cabin, 2 × 1,290 kW PCS (= 2.58 MVA) are available.
What are the advantages of the string topology in the 5,015 kWh BESS?
- Fault isolation (clusters work independently),
- no circular flows,
- balanced ageing of all batteries,
- High efficiency even with partial output,
- Fast maintenance thanks to modular components.
Is integration into existing energy systems possible?
Yes, the system can be integrated into PV systems, wind farms, charging infrastructure, microgrids or classic industrial networks - thanks to versatile EMS/SCADA interfaces such as RS485, Modbus TCP/RTU, IEC104 and IEC61850.
