Outdoor Liquid-Cooled Grid-Connected Integrated Cabinet
OD125261L2
Safe and Reliable
■ High-performance Lithium Iron Phosphate (LFP) batteries adopted, with 314Ah cell capacity and 1P260S series-parallel connection for
cell-level safety;
■ Four-fold safety protection: flammable gas detection, water immersion detection, temperature-sensitive aerosol fire extinguishing device,
and second-level cell health detection plus early warning;
■ Two-layer BMS architecture (1BCU + 5BMUs) enables real-time battery status monitoring, with multiple protections against overvoltage,
overcurrent and overheating, as well as precise control and balanced management.

Stable and Efficient
■ Adapted to peak-valley price difference mode and operating in the high-efficiency inversion range; the PCS maximum efficiency reaches 98.5%, and the system energy cycle efficiency is ≥90%;
■ String-type design enables independent operation of battery clusters without circulating current, with a cycle life of 8000 times (0.5P, 5%~95%DOD, 70%SOH) for high battery utilization;
■ Intelligent liquid cooling temperature control (modules) + air cooling temperature control (PCS) ensures low cell temperature difference, low
system power consumption, and ultra-wide temperature operation (-30℃~55℃);
■ Rated AC power 125kW, maximum power 138kW, total current harmonic distortion <3%, providing high power quality and complying with grid
connection standards.
Convenient Operation & Maintenance
■ Cloud real-time monitoring + local control; the EMS supports data collection, alarm protection, and power prediction, enabling unattended operation and OTA upgrade;
■ Fully factory pre-assembled with an All-in-One highly integrated and front-rear maintenance design, ensuring convenient transportation, installation, operation and maintenance throughout the process;
■ Modular design supports AC-side parallel operation of multiple cabinets for rapid capacity expansion to meet customized demands of large-capacity energy storage projects;
■ IP54 protection grade, default C3 corrosion protection grade (C4/C5 optional), resistant to high/low temperature and high humidity, suitable for various outdoor environments.
