FAQ
- What is the actual usable capacity and round-trip efficiency of the CubeArk 5MWh BESS container?
- The CubeArk-5000kWh delivers 5015.961kWh nominal energy with >=93.5% system cycle efficiency (FAT standard). Thanks to string architecture eliminating DC circulating currents, usable capacity increases by 15% compared to conventional parallel-cluster designs. Actual usable energy reaches approximately 4700kWh per cycle under standard operating conditions.
- What battery cells and cooling technology does this containerized energy storage system use?
- The system uses 314Ah LiFePO4 (LFP) prismatic cells configured in 1P1248S * 4 strings, with forced liquid cooling using a 50% ethylene glycol-water mixture. Liquid cooling maintains optimal cell temperature uniformity (+-2 elsius across all cells), extending cycle life and enabling reliable 0.5P continuous charge/discharge at 25 Celsius ambient temperature.
- Is this BESS container rated for outdoor installation in harsh or coastal environments?
- Yes. The CubeArk 5MWh container features IP55 ingress protection (dust-tight and water-jet resistant), C4 corrosion-proof grade (suitable for high-salinity coastal and industrial areas), and operates reliably at altitudes up to 2000m. The 42.5-ton steel container structure withstands extreme weather including heavy rain, sandstorms, and high humidity.
- What fire protection and safety features are built into the CubeArk 5MWh system?
- The system is equipped with an aerosol fire suppression system and module-level partitioned safety isolation------each battery module is physically separated by fire-resistant barriers. Combined with multi-layer BMS protection (over-voltage, under-voltage, over-temperature, short-circuit, and ground fault detection), this design prevents single-module thermal events from propagating to adjacent modules.
- Can multiple CubeArk 5MWh containers be connected in parallel for larger energy storage projects?
- Absolutely. The CubeArk Series is designed for flexible deployment and scalable expansion. Multiple 5MWh units can be paralleled on the AC side to build systems from 5MWh up to 50MWh or more. Communication protocols (Modbus-TCP, IEC61850, IEC104) support centralized EMS coordination across all paralleled containers for unified dispatch and monitoring.
- What are the primary applications for this commercial and industrial battery energy storage system?
- The CubeArk 5MWh BESS is engineered for: (1) Commercial & industrial peak shaving and demand charge reduction; (2) Utility-scale solar PV + storage integration and curtailment reduction; (3) Industrial microgrid and off-grid power supply for mining, oil & gas; (4) Grid frequency regulation and ancillary services; (5) Backup power for data centers, hospitals, and critical infrastructure.
- What warranty and expected cycle life does the LiFePO4 battery system offer?
- The 314Ah LiFePO4 cells are rated for 8000+ cycles at 0.5P and 80% DOD, with a design life exceeding 15 years under normal operating conditions. SUNARK provides a standard 10-year product warranty with optional extended service agreements. The liquid cooling system and intelligent thermal management significantly reduce cell degradation, ensuring long-term ROI for BESS investors.
- What communication protocols does the BESS support for grid integration and remote monitoring?
- The CubeArk 5MWh supports industry-standard protocols including Modbus-TCP, IEC61850, and IEC104, enabling direct integration with utility SCADA systems, third-party EMS platforms, and virtual power plant (VPP) aggregators. Remote firmware updates, real-time performance monitoring, and predictive maintenance alerts are accessible via SUNARK's cloud-based energy management platform.
