Key global certifications ensuring safety, grid compliance, and performance, including IEC, UL, CE, TÜV, and DNV.1. What are the key product lines in Wenergy’s C&I ESS portfolio?
96kWh/144kWh/192kWh/258kWh/289kWh AC-coupled cabinets: Integrated with PCS for grid-tied applications (e.g., peak shaving, PV self-consumption).
385kWh DC-coupled systems: Designed for large-scale DC integration (e.g., solar-plus-storage plants).
*Note: 258kWh uses 280Ah cells; 289kWh/385kWh use 314Ah cells for higher energy density.*
2. What is the system composition of Wenergy’s C&I ESS?
Battery clusters (LiFePO₄ cells, liquid-cooled packs).
Power conversion: PCS (AC-coupled) or high-voltage PDU (DC-coupled).
Safety systems: Aerosol fire suppression (Pack/Container-level), IP54-rated enclosures.
Smart controls: Tiered BMS (BMU/BCU/BAU), EMS for energy scheduling.
3. What certifications do Wenergy’s cabinets comply with?
All products meet:
Safety: IEC 62619, UL 1973 (battery), UL 9540A (fire).
Grid compliance: CE, UKCA, IEEE 1547 for grid interconnection.
Transport: UN38.3 for lithium batteries.
4. How does the thermal management system ensure safety?
Liquid cooling (50% glycol solution) maintains cell ΔT <3°C.
Operating range: -30°C to +55°C (discharge), 0°C to +60°C (charge).
Redundancy: Dual pumps + fail-safe controls.
What fire protection measures are implemented?
Dual-layer aerosol suppression:
Pack-level: 144g units (185°C thermal trigger, ≤12s response).
Container-level: 300g electric-start units (smoke/temperature detection).
Five-in-one sensors: H₂/CO/temperature/smoke/flame detection.
6. What are typical applications for these systems?
AC-coupled systems:
192 series (96/144/192kWh configurations):
✅With optional add-ons:
✅Standard functions: Peak shaving, demand charge reduction.
258/289kWh cabinets:
• Standard grid-tied functions only (no MPPT/STS/ATS by default):
Peak shaving
Frequency regulation
DC-coupled systems (385kWh):
• Solar farm ramp rate control (high-voltage DC direct coupling)
• Large-scale microgrids
7. What is the system efficiency and lifespan?
Round-trip efficiency: >89% (AC-coupled), >93% (DC-coupled).
Cycle life: 6,000 cycles at 80% DoD (10-year design life).
Warranty: 5 years (or 3,000 cycles) for batteries; 2 years for PCS/PDU.
8. How are the cabinets installed and maintained?
Foundation: 300mm elevated concrete base (±5mm flatness).
Grid connection: Plug-and-play with pre-configured PCS/PDU.
Maintenance: Remote BMS monitoring + annual on-site inspections (cell balancing, coolant checks).
9. What communication protocols are supported?
Standard: CAN2.0B, Modbus RTU over RS485.
Optional: IEC 61850, DNP3 for utility-scale integration.
Cloud EMS: Supports dynamic tariff optimization and peak load shifting.
10. How does Wenergy ensure cost-effectiveness?
CAPEX: 15-20% lower $/kWh vs. competitors (passive cell balancing, modular design).
OPEX: 30% less land use (vs. containerized systems) + smart EMS for ROI optimization.
Scalability: Parallel up to 16 units (AC) or 10 clusters (DC).
