Frequently asked questions (FAQ)

  • 1. What is the system composition of Wenergy's containerized BESS?

    Wenergy’s BESS containers integrate battery clusters (with Li-ion cells), a high-voltage PDU, DC combiner cabinet, liquid cooling thermal management system, and multi-level fire suppression (pack & container-level aerosol). The modular design supports 3.44MWh,3.85MWh to 5.016MWh configurations per unit, compliant with IEC/UL/GB standards.

  • 2. What are the key safety features of Wenergy's BESS containers?

    Our systems feature:

    Three-tier protection:

    Cell/pack/cluster-level BMS with overcharge/overcurrent/temperature monitoring.

    Fire safety:

    Dual aerosol suppression (≤12s response) + five-in-one detection (smoke/temperature/H₂/CO).

    IP54/IP65 enclosures and fault-tolerant grounding per UL/IEC 62477-1.

  • What certifications do Wenergy's BESS products hold?

    Space: 6.06m(L)×2.44m(W)×2.9m(H); 20% land savings vs. 3.85MWh.

  • 7. What is the expected lifespan and warranty?

    Design life: 10+ years (6,000 cycles at 80% DoD).

    Warranty: 5 years (or 3,000 cycles) for batteries; 2 years for PCS/auxiliaries.

    Case-by-case variations may apply based on specific project requirements or conditions. Please contact us for more details on customized warranty options.

  • 8. What communication protocols are supported?

    Standard: CAN/RS485/Ethernet for PCS/SCADA integration.

    Optional: Modbus TCP, IEC 61850 for grid compliance.

  • 9. How does the 5.016MWh model improve project economics?

    CAPEX: ~15% lower $/kWh vs. 3.85MWh (fewer units).

    OPEX: 20% land reduction + lower balance-of-system costs.

    Note: Optimal for projects >200MWh (offsetting transport/permitting costs).

  • 10. What after-sales support is provided?

    Remote monitoring: 24/7 performance tracking via Wenergy EMS.

    On-site: Certified technicians for commissioning/maintenance.

    Spares: Global stock of critical parts (PDUs, cooling units).
