Product Description

Energy Storage System Overview System Component System Feature System Monitoring System Installation
Energy Storage Module 1 Energy Storage Module 2 Energy Storage Module 3
Our Advantages
1. All-in-One Design Pre-installed containerized systems (battery + PV input) reduce installation/commissioning time and costs. Plug-and-play deployment for rapid setup.
2. High Efficiency & Reliability AI-optimized air-cooling maintains full power at 45°C (IP54 rated). Round-trip efficiency (RTE) 3% higher than competitors. LFP (LiFePO4) batteries ensure safety and long cycle life.
3. Scalability & Flexibility Modular cabinets/containers allow flexible capacity customization (e.g., 100kWh–5MWh). Supports on/off-grid operation and parallel deployment.
4. Cost Savings Reduces energy costs by 30%–70% through peak shaving, solar integration, and grid independence. Lower maintenance costs via cloud monitoring.
5. Safety Multi-layer protection: automatic fire extinguishers, PACK-level immersion fire tech, and active thermal management. Cell-level temperature control (<5°C variation).
6. Smart Management Cloud-based remote monitoring, AI energy optimization, and 24/7 fault detection. Adaptive charging/discharging strategies maximize ROI.
7. Manufacturing Strength Fully automated production lines (air/liquid-cooled PACKs). ODM capabilities and GWh-scale project experience.

Product Iterations & Optimization
Eight product iterations have been completed. Our energy storage modules are continuously developed and optimized:
  • Curved design and air duct turbine design for superior heat dissipation.
  • Single cell air duct design, temperature range control < 5°C.
  • Enhanced insulation performance and thermal simulation for consistency.
  • CTP (Cell-to-Pack) no-module design, reducing costs by 30% and increasing efficiency by 100%.
  • External quick-plug design for simple BMS and fan maintenance.
