  1. Ultra-Safe Operation: A+ grade LiFePO4 cells, multi-level fuses, aerosol fire suppression, and triple-stage hazard detection (active exhaust + passive explosion-proof).
  2. Military-Grade Resilience: IP54 rating + C3/C5 corrosion resistance for harsh environments (high humidity, salt spray).
  3. Plug-and-Play Deployment: Modular design, side-outlet cabling, and integrated liquid cooling simplify installation and maintenance.
  4. Future-Proof Scalability: Flexible parallel expansion to 250kW, 500kW, or 1MW clusters without capacity degradation.
  5. High Efficiency: 98.2% PCS efficiency, 8,000+ cycles @25°C, and 15-year design lifespan.

High-Density 261kWh Liquid-Cooled All-in-One BESS for Commercial & Industrial Applications1

Product Introduction:
The Lithium Valley ACE Series is a cutting-edge, liquid-cooled Battery Energy Storage System (BESS) designed for demanding commercial and industrial environments. With a compact footprint and industry density (261kWh per cabinet), it integrates advanced safety mechanisms, robust environmental resilience, and flexible scalability. Its modular architecture supports seamless AC/DC expansion and multi-cluster management up to 1MW, enabling peak shaving, microgrid operation, and emergency backup with zero parallel capacity loss.

Key Advantages:

  1. Ultra-Safe Operation: A+ grade LiFePO4 cells, multi-level fuses, aerosol fire suppression, and triple-stage hazard detection (active exhaust + passive explosion-proof).

  2. Military-Grade Resilience: IP54 rating + C3/C5 corrosion resistance for harsh environments (high humidity, salt spray).

  3. Plug-and-Play Deployment: Modular design, side-outlet cabling, and integrated liquid cooling simplify installation and maintenance.

  4. Future-Proof Scalability: Flexible parallel expansion to 250kW, 500kW, or 1MW clusters without capacity degradation.

  5. High Efficiency: 98.2% PCS efficiency, 8,000+ cycles @25°C, and 15-year design lifespan.

FAQ:
Q1: How much space does a 261kWh unit require?
A: The cabinet occupies just 1.3m × 1.55m footprint, ideal for space-constrained sites.

Q2: Is maintenance complex?
A: No. Modular design and side-access outlets enable tool-free component swaps and rapid servicing.

Q3: Can it operate in coastal areas?
A: Yes. C5 corrosion resistance and IP54 rating protect against salt spray and high humidity.

Q4: What is the expected lifespan?
A: 15-year design life with ≥8,000 cycles at 25°C, ensuring long-term ROI.

Q5: Does expansion require downtime?
A: No. Hot-swappable modules allow capacity additions without system shutdown.
