Optimal Costs & Footprint Optimization
Designed to significantly reduce total cost of ownership (TCO) for large-scale energy infrastructure, the Aqua C2.5S series implements an innovative back-to-back and side-by-side layout configuration. This engineering breakthrough minimizes physical land requirements, offering massive footprint optimization for constrained project sites. To accelerate project deployment timelines, the system integrates a factory-installed AC/DC bi-directional inverter, reducing on-site wiring, engineering complexities, and overall commissioning time.

Ultimate Security & Global Grid Compliance
Safety is paramount for commercial and industrial energy storage installations. The Aqua C2.5S incorporates multi-level electrical isolation, advanced arc flash analysis, and a comprehensive, collaborative protection matrix. The integrated fire suppression system is fully engineered for strict permitting environments, featuring an industrial fire alarm control panel, highly sensitive smoke, heat, and gas detectors, alarm bells, and horn strobes.
The container includes an NFPA 69-compliant ventilation system, a standard fire hose connection to dry pipes with internal sprinkler heads, and offers optional aerosol and deflagration vent panels. Furthermore, the enclosure is qualified to withstand seismic disruptions, conforming to IEEE 693 moderate seismic level standards as a default, with high seismic level certification available as an option.
FAQ
Q: Is the container shipped fully assembled with cells installed, or do they require on-site integration?
A: The system is shipped fully integrated with battery modules factory-installed in the 20ft container to ensure strict quality control. On-site work is strictly limited to positioning, external wiring, and final commissioning.
Q: What is the maximum cell-to-cell temperature variance maintained by your liquid cooling system?
A: Our intelligent liquid-cooled thermal management system actively maintains cell-to-cell temperature variance under 3°C, drastically mitigating localized degradation and optimizing system round-trip efficiency (RTE).
Q: Can you provide the full UL 9540A test report for local authority (AHJ) permitting?
A: Yes. We provide the complete third-party UL 9540A cell, module, and unit-level thermal runaway test report to accelerate your local zoning and Authority Having Jurisdiction (AHJ) approvals.
Q: How does the fire suppression system handle gas accumulation prior to thermal runaway?
A: The system includes sensitive gas detectors integrated with an NFPA 69-compliant ventilation system to exhaust combustible gases before ignition. If an event occurs, it triggers multi-level containment, including dry pipe sprinklers and optional aerosol suppression.
Q: What specific metrics are captured by your rapid fault recording?
A: The BMS records millisecond-level pre- and post-fault data, including cell voltages, string currents, module temperatures, coolant pressures, and digital I/O states. This data allows our technical team to perform rapid remote root-cause analysis.
