Quantum N2.5 Utility-Scale Energy Storage System Utility Sodium-Ion BESS | 1.25MW | 2.5MWh The ZTTEK Quantum N2.5 is a factory-prefabricated, fully integrated utility-scale battery energy storage system built on sodium-ion chemistry. Delivered as a standard 20-foot container, the Quantum N2.5 ESS provides a cost-stable, cold-climate-capable alternative to lithium-based storage for large-scale grid projects where modular deployment, resource-independent chemistry, and wide operating temperature range are priorities.

Sodium-Ion Utility Platform with Modular Capacity

A utility-grade sodium-ion BESS designed for cost-sensitive and climate-demanding applications.
- Installed energy: 2.5 MWh per container; rated power: 1.25 MW
- Battery chemistry: Sodium-ion (Na-ion); cell nominal voltage: 3.0 V
- Cell capacity options: 185 Ah / 210 Ah; charge/discharge rate: 0.5C
- Modular 2.5 MWh container format supports phased investment and incremental expansion
Sodium-ion chemistry avoids dependence on lithium, cobalt, and nickel, offering a structurally cost-stable supply chain for large-volume procurement.



Factory-Prefabricated, Fully Integrated Container

All core components — batteries, PCS, thermal management, and fire protection — are integrated and factory-tested before delivery.
- Delivered as a complete, ready-to-connect 20-foot container (6058 × 2438 × 2896 mm)
- On-site work limited to hoisting, electrical, and communication connections
- No on-site system assembly or component-level integration required
This approach shortens project delivery time and reduces on-site labor, commissioning risk, and schedule uncertainty.



Simplified O&M, Lower Lifecycle Cost

Designed to minimize maintenance burden and total cost of ownership over the project lifetime.
- Modular design for fast fault localization and component replacement without full system shutdown
- Remote monitoring and intelligent O&M support, reducing on-site visits
- Standardized container format simplifies spare-part management and capacity scaling



Multi-Level Safety Architecture

A layered safety system designed for unattended outdoor utility environments.
- Pack-level fire detection with independent perfluorohexanone suppression system
- Explosion-proof ventilation and backup water firefighting interface
- Integrated thermal management for safe operation under extreme conditions
- IP54 protection; high-strength steel container structure
The multi-level design improves early fault detection, risk containment, and operational reliability in complex outdoor environments.



Wide-Range Environmental Adaptability

Sodium-ion chemistry offers inherently superior low-temperature performance compared to LFP, making the Quantum N2.5 particularly suited to cold-region deployments.
- Operating temperature: -30°C to +55°C
- Relative humidity: 0–95% (non-condensing)
- Altitude capability: ≤3000 m
- Protection rating: IP54
Suitable for high-latitude, high-altitude, and extreme-climate utility projects where lithium-based ESS performance is constrained.
