Liquid-Cooling C&I Energy Storage System
The Max-Pro 262kWh Battery Cabinet represents the next generation of Commercial & Industrial ESS (C&I ESS) technology. Designed for high-performance energy management, this all-in-one Liquid Cooling BESS offers a robust 125kW power output, making it the ideal solution for enterprises seeking to optimize energy costs through peak shaving and demand charge management.
By integrating high-capacity 315Ah LFP cells with advanced thermal management, the Max-Pro cabinet ensures long-term reliability and a superior return on investment for microgrid and PV-plus-storage integration projects.
Core Advantages for Project Developers
Advanced Liquid-Cooled Thermal Management:
Unlike traditional air-cooled systems, our liquid-cooling technology maintains a uniform temperature gradient across all cells (typically within 3℃), significantly extending the battery cycle life and enhancing system efficiency in high-ambient environments.
Four-Tier Fire Safety Architecture:
Safety is our cornerstone. To meet the most stringent global standards, including UL9540A, the Max-Pro is equipped with an integrated safety suite: Aerosol suppression, combustible gas detection, active ventilation, and a water-based fire extinguishing backup.
High Energy Density & Compact Footprint:
Utilizing a 1P260S configuration with 315Ah LFP chemistry, we deliver 262kWh of usable energy within a compact $950 \times 1400 \times 2330\text{ mm}$ footprint, minimizing land use and installation costs.
Ruggedized for Harsh Environments:
With an IP55 ingress protection rating and C4-M anti-corrosion grading, this cabinet is engineered for durability in coastal regions and high-altitude sites (up to 4000m).

Multi-Tiered Fire Suppression & UL9540A Compliance
Advanced Detection and Active Protection
The cabinet is equipped with high-sensitivity sensors that monitor for both heat and combustible gas accumulation. At the earliest sign of an anomaly, the system triggers active ventilation to prevent the buildup of hazardous gases. If a thermal event is detected, our Aerosol suppression system is deployed instantly to chemically interrupted the fire cycle at the molecular level, ensuring rapid suppression without damaging the surrounding electrical components.
Redundancy for Total Peace of Mind
Beyond chemical suppression, the Max-Pro includes a secondary water-based extinguishing system as a final safeguard. This dual-action approach ensures that the system remains protected under all circumstances. By rigorously adhering to the UL9540A large-scale fire testing standards, we provide our clients with the necessary documentation to streamline insurance approvals and local grid permitting. Choosing the Max-Pro means investing in a system where high energy density and uncompromising safety coexist.
FAQ
Q: Is the 262kWh capacity the "nominal" or "usable" energy?
A: The 262kWh refers to the Rated Energy at the DC side. Depending on your Depth of Discharge (DoD) settings-typically 90% to 95%-the usable AC energy will be slightly lower due to conversion efficiencies, ensuring the longevity of the 315Ah LFP cells.
Q: Does this cabinet have a UL9540A test report available for local permitting?
A: Yes. We understand that UL9540A is a mandatory requirement for many jurisdictions. We provide the full test report, which documents the system's behavior during a forced thermal runaway event, proving our multi-tier fire suppression is effective for indoor and outdoor installations.
Q: Can we parallel multiple 262kWh units for a larger (e.g., 1MWh+) project?
A: Yes. The system is modular by design. You can parallel multiple cabinets on the AC side via a centralized transformer or switchgear. The Modbus TCP protocol allows a master controller to manage the entire cluster as a single power plant.
Q: Is the system "plug-and-play" or does it require on-site integration?
A: It is a pre-integrated, all-in-one cabinet. The batteries, BMS, PCS, and fire suppression are pre-installed and tested at our factory. On-site, you only need to connect the AC power cables and communication lines.
Q: What is the standard warranty and what does it cover?
A: We offer a standard 5-year comprehensive warranty, with options to extend to 10 years. It covers the battery throughput (MWh) or calendar years, whichever comes first, ensuring the system maintains at least 70-80% of its capacity.
