MRACK-706 | 705.54 kWh Rack-Mounted BESS

Additional information

Rack-Scale Energy Storage. Enterprise-Grade Protection.

The MRACK-706 sets the standard for rack-mounted BESS platforms, delivering 705.54 kWh in a single cabinet with an IP66-rated battery compartment — a protection level typically associated with outdoor containerized systems, now available in a rack form factor. Designed for data centers, mission-critical facilities, and C&I applications where space efficiency and protection integrity are equally important, the TenerL combines CATL’s world-leading cell technology with the most comprehensive certification portfolio of any rack-mounted BESS product in its class.

Performance Specifications

  • IP66 Battery Compartment: - The highest IP rating in its class — providing dust-tight, high-pressure jet protection for battery cells even in demanding environments
  • 705 kWh in a Rack Form Factor: - Eliminates the need for containerized BESS infrastructure for facilities needing sub-MWh storage — saving civil engineering costs and deployment time
  • Most Complete Certification in Class: - IEC, UL, CE, UK CA, UN38.3, and NFPA compliance — accepted by every major utility, insurer, and AHJ globally
  • 1,500V High-Voltage System: -Maximizes inverter efficiency and minimizes balance-of-system losses for optimal system LCOE
  • Operating Range from -35°C to +55°C: - Full performance from arctic deployments to desert environments — no derating at altitudes up to 4,000m
  • Liquid Cooling: - Active thermal management maintains cell temperatures for maximum cycle life and consistent power delivery
  • 0.5P / 2-Hour Configuration: Optimized for peak shaving, demand charge reduction, and capacity market participation with 2-hour full discharge capability
  • UN38.3 Certified:Transport-certified for international shipping and deployment — removes logistics barriers for global project developers
  • IEC 60730 Compliance: Automatic electrical controls standard compliance for integration with building management and industrial control systems

Applications Built on Proven Performance

  • Data Center BESS: High-density backup, demand management, and grid services in a rack format compatible with existing data center infrastructure
  • Telecom & Network Infrastructure: High-reliability backup and energy storage in space-constrained technical rooms
  • Mission-Critical Facilities: Hospitals, emergency operations centers, and government facilities requiring superior protection ratings
  • C&I Energy Management: Commercial buildings and industrial facilities targeting demand charge reduction without containerized BESS
  • Global Project Deployment: UN38.3 transport certification enables international shipping for distributed project portfolios
