Quantum L5 Utility-Scale Energy Storage System Utility LFP BESS | 2.5MW | 5MWh The ZTTEK Quantum L5 is a factory-prefabricated, fully integrated utility-scale battery energy storage system built on LFP chemistry. Delivered as a standard 20-foot container, the Quantum L5 ESS is designed for grid-side and power-station projects requiring high single-container energy capacity, proven long-cycle performance, and minimal on-site construction.

High-Voltage, High-Capacity Utility Configuration

Optimized for MW-scale grid operation with a high-voltage architecture that simplifies parallel deployment.
- Installed energy: 5 MWh per container; rated power: 2.5 MW
- System rated voltage: 1331.2 V (1500 V DC class)
- Battery configuration: 12P416S; cell nominal voltage: 3.2 V / 314 Ah
- Rated battery pack capacity: 104.4992 kWh
- Charge / discharge rate: 0.5C
The 1331.2 V high-voltage design supports efficient MW-level operation and simplifies parallel connection in large energy storage stations.



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 system expansion



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

Built for real-world outdoor deployment across diverse geographic and climatic conditions.
- Operating temperature: -30°C to +55°C
- Relative humidity: 0–95% (non-condensing)
- Altitude capability: ≤3000 m
- Protection rating: IP54
