Sunrange 261KWH liquied cooling BESS

Key Advantages

  • Superior Liquid Cooling Performance
     
    Liquid circulation heat dissipation eliminates hot spots inside the battery cluster, maintains consistent temperature across all cells, reduces auxiliary power consumption by 20% vs air cooling, and lifts battery cycle life by over 20%. Stable performance under high-temperature summer outdoor environments.

 

  • Fully Integrated All-in-One Plug & Play
     
    All core subsystems pre-installed in factory; deliver to site, connect grid and PV to operate instantly. Greatly cuts construction period and civil engineering cost.

 

  • Multi-Layer Safety Protection
     
    LiFePO4 intrinsic safety + PACK-level fire isolation + cabinet automatic fire suppression + temperature leakage real-time monitoring + overcharge/over-discharge/short-circuit multi-protection logic to prevent thermal runaway risks.

 

  • Intelligent Cloud Monitoring
     
    Ethernet communication supports remote real-time data tracking, fault early warning, peak-valley automatic switching, PV self-consumption optimization and unattended operation.

 

  • Flexible Application Scenarios
  • Factory peak shaving & valley filling, commercial building backup power, rooftop solar storage, charging station energy buffer, remote microgrid, demand response revenue optimization.

 

 

FAQ

Q1: What capacity range does the Sunrange liquid cooled outdoor BESS cover, and what core advantages does liquid cooling bring?
 
A: This product line offers adjustable energy capacity from 193kWh to 261kWh for outdoor commercial & industrial deployment. Its closed-loop liquid cooling system keeps cell temperature difference within ±2°C, supporting higher continuous charge/discharge power, extending battery cycle life by around 20%, and delivering stable performance in extreme hot or cold outdoor environments compared to air-cooled models.
 
Q2: Can this Sunrange BESS be directly installed outdoors without an extra equipment room? What is its enclosure protection rating?
 
A: Yes, it is fully designed for direct outdoor placement with no dedicated shelter required. The cabinet adopts IP55 dust and waterproof protection grade, paired with integrated liquid heating & cooling modules to support stable operation under ambient temperatures of -30°C to 55°C, adapting to all climate zones.

 

Q3: What main application scenarios is the 193–261kWh Sunrange liquid cooled outdoor BESS suitable for?
 
A: It serves multiple commercial & industrial use cases: peak shaving & demand charge reduction, solar PV energy storage & load shifting, critical facility backup power, microgrid stabilization, virtual power plant (VPP) access, and factory power quality optimization.

 

Q4: Is the Sunrange 193–261kWh liquid cooled BESS modular and expandable for larger energy storage projects?
 
A: Absolutely. The all-in-one cabinet supports AC parallel connection of multiple units. You can combine several 193kWh/261kWh modules to scale up total capacity to multi-MWh, controlled by a unified central EMS platform for coordinated charge and discharge scheduling.

 

Q5: What safety protection systems are integrated into this outdoor liquid cooled BESS?
 
A: It adopts multi-layer full safety design: real-time BMS cell temperature & voltage monitoring, liquid coolant leak detection, thermal runaway early warning, pack-level aerosol fire suppression, explosion relief valves, and emergency E-Stop button. It complies with IEC 62619, UN38.3 and other global energy storage safety standards.

 

Q6: Does the Sunrange liquid cooled BESS come with built-in PCS and EMS? What communication protocols does it support?
 
A: Each cabinet integrates a high-efficiency bidirectional PCS and intelligent EMS out of the box, no separate inverter purchase needed. It supports mainstream communication protocols including Modbus RTU/TCP, CANbus, MQTT and IEC 104, enabling seamless connection with solar inverters, generators, cloud monitoring platforms and grid dispatching systems.
