The Huawei Smart String ESS features a modular design, comprising the Battery Cabin, Smart Rack Controller Cabin, and Control Unit Cabin. It integrates lithium iron phosphate (LFP) batteries and racks with advanced functionalities, including a Battery Management System (BMS), heating, ventilation, and air conditioning (HVAC) system, lighting, fire detection and automatic fire extinguishing system, security and emergency systems. Additionally, it incorporates surge protection devices (SPDs), grounding protection mechanisms, and grounding fault detection to ensure safety, reliability, and efficient operation.
Huawei offers four standard models of Smart String ESSs, all housed in 20-foot containers: LUNA2000-2.0MWH-1H1 (1-hour power backup, C-rating of 1), LUNA2000-2.0MWH-2H1 (2-hour power backup, C-rating of 0.5), LUNA2000-2.0MWH-4H1 (4-hour power backup, C-rating of 0.25), and LUNA2000-1.0MWH-1H1 (1-hour power backup, C-rating of 1, providing up to 1MW for 1MWh).
Key Benefits
More Energy, Higher Efficiency
- 15% More Discharge Energy: An optimizer is configured for each battery pack to prevent capacity loss caused by mismatch of packs connected in series in a battery rack. A smart controller is configured for each battery rack to prevent capacity loss caused by cross current. As a result, the lifetime discharge throughput is increased by 15%.
- Efficient Cooling: The smart air cooling in the container ensures that the temperature difference inside the container is less than 3°C@0.5C. This prolongs the service life of batteries for the same environment conditions.
Safe & Reliable
- Modular Design: The cooling system, battery system, and PCS are designed with modularity in mind, featuring a 200kVA PCS. This design enhances system availability to 99.9%, ensuring reliable performance.
- Quadruple Safety Protection: The internal short circuit prediction system accurately detects and prevents unexpected short circuits, significantly enhancing the safety of the energy storage system.
- Standard 20″ Container: Designed for easy transport and deployment, the standard 20″ container ensures convenience and flexibility in installation.
Simple O&M
- Automatic SOC Calibration: During battery replacement, the State of Charge (SOC) is automatically calibrated, eliminating the need for manual adjustments or periodic calibration. Onsite O&M personnel can directly replace battery packs, reducing O&M costs by over 90%.
- No Periodic Balancing: The system is maintenance-free, offering significant cost savings by eliminating the need for periodic balancing.
- Remote Management: With remote management, there is no need for on-site expert visits, resulting in savings of approximately €235k per 100 MWh annually.
Flexible and Scalable
- Adaptable Design: Easily scales to meet varying energy demands with modular PCS and storage containers.
