Sodium-Ion Utility-Scale BESS

Utility-Scale BESS (Na-ion, 1.25MW / 2.5MWh)

Model: ZT-BEES-Na-2.5M

Sodium-Ion Utility Platform with Modular Capacity

ZTTEK Quantum N2.5 provides a utility-scale sodium-ion solution for projects prioritizing cost stability and modular deployment.

  • Installed energy capacity: 2.5 MWh per container
  • Rated power output: 1.25 MW
  • Sodium-ion cell voltage: 3.0 V
  • Cell capacity options: 185 Ah / 210 Ah
  • Charge / discharge rate: 0.5C

The modular 2.5 MWh container format supports phased investment and flexible system expansion.

Factory-Prefabricated Container Design

All core components are integrated and tested at the factory, minimizing on-site construction work.

  • Batteries, PCS, thermal management, and fire protection integrated in one container
  • Delivered as a standard 20-foot container (6058 × 2438 × 2896 mm)
  • On-site work limited to hoisting and electrical/communication connections
This approach significantly shortens project delivery time and reduces on-site labor and installation risks.

Multi-Layer Safety & Environmental Adaptability

Quantum N2.5 integrates comprehensive safety and environmental protection measures for outdoor utility deployment.

  • High-strength steel container with protection level IP54 or higher, resistant to high/low temperatures, high humidity, and dusty conditions
  • Pack-level fire detection and independent perfluorohexanone fire suppression system
  • Explosion-proof ventilation design and backup water firefighting interface
  • Integrated thermal management system ensures safe operation under extreme conditions
Compared with distributed energy storage systems, this layered design enhances early fault detection, improves risk controllability, and provides superior operational reliability in complex environments.

Outdoor-Ready Containerized Design

The system is designed for outdoor utility deployment.

  • Protection level: IP54
  • Operating temperature range: -30°C to +55°C
  • Relative humidity: 0–95% (non-condensing)
  • Altitude capability: ≤3000 m
  • Standard 20-foot container
Designed for deployment in a wide range of geographic and climatic conditions, ensuring reliable performance under real-world utility environments.

Flexible System Voltage Configuration

All core components are integrated and tested at the factory, minimizing on-site construction work.

  • Batteries, PCS, thermal management, and fire protection integrated in one container
  • Delivered as a standard 20-foot container (6058 × 2438 × 2896 mm)
  • On-site work limited to hoisting and electrical/communication connections
This approach significantly shortens project delivery time and reduces on-site labor and installation risks.

Simplified Operation & Maintenance

Lower Lifecycle Cost

  • Modular design enables easy fault localization and component replacement without full system shutdown
  • Supports remote monitoring and intelligent O&M, reducing on-site maintenance frequency
  • Optimized for long-term operational efficiency, lowering total cost of ownership
