- Safety and reliability: Incorporates LFP battery technology with multi-layer BMS protection, thermal management systems, and integrated fire safety at module level.
- Advanced PCS energy management: The bidirectional PCS coordinates energy flow between multiple generation sources and site loads to maintain system stability.
- Hybrid and microgrid integration: Suitable for integration into large hybrid systems combining diesel generation, solar PV, and grid supply.
- Modular and scalable architecture: Supports deployment as part of larger energy systems, with flexibility for expansion and system configuration.
- Remote monitoring and performance visibility: Enables real-time system monitoring, diagnostics, and operational control.
- 40FT containerised deployment: Designed for efficient transport and installation on large-scale or remote sites.
- Durable design: IP54-rated enclosure supports operation in harsh environmental conditions.
The ESU1250-2400 stores large volumes of energy and dispatches it to maintain system stability across high-demand operations. Its bidirectional Power Conversion System (PCS) manages energy exchange between battery storage, diesel gensets, solar PV, and site loads in real time.
During periods of low demand or excess generation, energy is stored within the system. When demand increases, the stored energy is discharged to support peak loads and reduce strain on primary generation assets.
Within complex hybrid or microgrid environments, the system plays a central role in balancing supply and demand, maintaining voltage and frequency stability, and improving overall system performance. This enables more efficient operation of large-scale energy systems operating in remote or infrastructure-constrained locations.
Typical Applications of Containerised BESS
- Large remote mine sites and major infrastructure & construction projects
- Industrial and utility-scale power systems
- Hybrid microgrids and off-grid energy systems
- High-demand temporary or permanent power installations
Fuelfix BESS in Action
Real-World Operations
EuropeIn a commercial deployment in Europe, SCU implemented a containerised energy storage system to increase solar PV utilisation within an existing power setup. The system stored excess solar generation during low demand periods and discharged it when required, reducing reliance on external energy sources and improving overall system efficiency.
This type of configuration reflects how containerised BESS can be applied in hybrid environments, including Australian mining and infrastructure sites, where integrating solar PV with diesel gensets requires stable, responsive energy management.Frequently Asked Questions
