High-Efficiency Liquid-Cooled BESS
Maximize your energy independence and operational stability with the Max-Classic 262kWh Energy Storage Solution. Engineered specifically for commercial and industrial (C&I) applications, this all-in-one liquid-cooled cabinet represents the next generation of Industrial Battery Energy Storage (BESS). By integrating high-capacity 315Ah LFP cells with advanced thermal management, we deliver a system that prioritizes safety, longevity, and a lower Levelized Cost of Storage (LCOS).
Core Advantages for Professional Buyers
Next-Gen 315Ah LFP Technology: Moving beyond standard 280Ah cells, our system utilizes 315Ah LFP battery cells in a 1P260S configuration. This provides higher energy density and superior cycle life, ensuring your investment delivers consistent performance over a decade of heavy-duty cycling.
Rugged Reliability for Harsh Environments: With an IP55 ingress protection rating and C4-M anti-corrosion grade, this unit is built for coastal areas, high-humidity sites, and industrial zones. It operates reliably in extreme temperatures ranging from -20 °C to 55 °C and at altitudes up to 4000 meters.
Certifications & Compliance
As a specialized BESS manufacturer, we understand that global deployment requires strict adherence to international standards. The Max-Classic is fully certified and tested according to:
- Safety: UL 9540A (Thermal Runaway Fire Test), UL 1973, IEC 62619, IEC 63056.
- Grid & Electrical: IEC 62477, EN 61000.

A Zero-Compromise Approach to System Protection
For project developers and safety officers, the primary concern with large-scale LFP installations is thermal runaway mitigation. The Max-Classic 262kWh addresses this with a sophisticated, integrated fire suppression architecture that goes far beyond simple extinguishers.
- Early-Stage Detection: The system is equipped with high-sensitivity combustible gas detection and smoke sensors. By identifying the "off-gassing" phase before a fire even starts, the system can trigger emergency venting and isolate the affected battery string, potentially preventing an incident before it escalates.
- Dual-Medium Suppression: We utilize a primary Aerosol suppression system designed to chemically interrupt fire at the molecular level without damaging sensitive electronics. For extreme scenarios, the cabinet is pre-plumbed with a water extinguishing system, providing a final, high-capacity cooling barrier to prevent thermal propagation to adjacent units.
- Active Emergency Ventilation: In the event of gas buildup, the integrated ventilation system automatically activates to exhaust hazardous vapors, maintaining a safe internal atmosphere and reducing the risk of pressure-related cabinet failure.
- Certified Peace of Mind: All safety protocols are validated by the UL 9540A thermal runaway fire test report. This certification is essential for modern grid-tie projects, as it provides the empirical data required by insurance providers and local fire authorities to approve installations in high-density or critical infrastructure zones.
FAQ
Q: How does the liquid-cooling system handle extreme ambient temperatures of 50°C+?
A: Our active liquid-cooling system is designed with a high-capacity heat exchanger. Unlike air-cooled units that lose efficiency as ambient temperatures rise, the liquid medium maintains a cell temperature variance of <3°C, ensuring the system operates at full power even in desert-like conditions without thermal derating.
Q: Can this unit be paralleled for multi-megawatt projects?
A: Absolutely. The system is designed for modular scalability. Multiple 262kWh cabinets can be paralleled on the DC or AC side (depending on your PCS configuration) to meet MWh-level requirements, managed by a centralized Master BMS.
Q: How does the C4-M anti-corrosion rating benefit coastal installations?
A: C4-M is a high-durability industrial rating. It means the cabinet exterior and intake systems are treated to withstand high-salinity and high-humidity environments, preventing rust and structural degradation for at least 15 years in coastal zones.
Q: What communication protocols are supported for EMS integration?
A: The system natively supports Modbus TCP and CAN communication via a standard LAN interface. This ensures seamless "plug-and-play" integration with most Tier-1 Energy Management Systems (EMS) and SCADA platforms.
Q: What is the Auxiliary Power consumption of the cooling and safety systems?
A: Our auxiliary power consumption is highly optimized, typically staying below 2% of the rated power. The system uses intelligent variable-frequency pumps that only ramp up when thermal thresholds are reached.
