125kW 261kWh Liquid Cooling All-in-One C&I Energy Storage Cabinet with CAN RS485

The GYC-ESS-125LC is a next-generation all-in-one commercial and industrial energy storage cabinet engineered for demanding applications. Delivering 125kW rated AC power output with 261.2kWh usable energy capacity, this fully integrated system combines precision liquid cooling technology, intelligent multi-protocol communication, and a pre-assembled plug-and-play design to dramatically reduce on-site commissioning time and total project cost. Built with automotive-grade LiFePO4 battery cells and a comprehensive multi-layer safety architecture, the cabinet ensures reliable, long-duration operation for factories, warehouses, solar PV stations, EV charging hubs, and microgrid projects.

Unlike traditional air-cooled container solutions that struggle with uneven cell temperatures and excessive auxiliary power consumption, the GYC-ESS-125LC features an active liquid circulation cooling loop with a variable frequency pump. This precision thermal management system maintains cell-to-cell temperature deviation within 2°C across the entire battery array, effectively eliminating hot spots, slowing cell aging, and extending operational lifespan well beyond 6,000 cycles. The liquid cooling approach also reduces auxiliary power draw by up to 35% compared to equivalent air-cooled systems, directly improving round-trip energy efficiency and lowering the levelized cost of storage over the system lifetime.

Communication flexibility is built into the core of this cabinet. The integrated energy management controller supports CAN 2.0B, RS485, Modbus TCP/IP, Ethernet, and 4G/WiFi cloud connectivity simultaneously, enabling seamless integration with existing SCADA platforms, third-party EMS software, and remote operation centers. Operators can monitor real-time SOC, SOH, cell voltages, temperatures, charge/discharge power, and cumulative throughput from any device with an internet connection. Automated alarm push notifications via SMS and email ensure rapid response to any anomaly, minimizing downtime risk in mission-critical installations.

• Precision Liquid Cooling Technology: Active variable frequency liquid circulation loop maintains cell temperature uniformity within ±2°C, eliminating thermal hot spots and extending battery cycle life beyond 6,000 cycles at 80% DOD. Reduces auxiliary power consumption by 35% versus forced-air designs while enabling higher pack density.
• All-in-One Pre-Assembled Cabinet: Factory-integrated PCS, battery modules, liquid cooling unit, fire suppression system, and EMS controller in a single outdoor-rated enclosure. Arrives on-site fully tested, requiring only AC grid connection and communication cable termination, reducing commissioning from weeks to hours.
• CAN RS485 Multi-Protocol Communication: Simultaneous CAN 2.0B, RS485, Modbus TCP/IP, Ethernet, and 4G/WiFi cloud interfaces provide maximum integration flexibility. Compatible with leading SCADA and EMS platforms. Remote firmware updates and cloud-based monitoring portal included as standard.
• Integrated Fire Suppression System: Multi-layer fire safety architecture featuring per-pack aerosol automatic fire suppression units, optical smoke detection sensors, and thermal runaway gas early-warning modules. The system triggers autonomous suppression within milliseconds of detection, well before thermal propagation can occur across adjacent battery modules.
• Dual Grid Mode Operation: Supports both grid-tied and off-grid island operation with seamless sub-20ms transfer switching. Enables peak shaving, valley filling, demand charge reduction, PV self-consumption optimization, and emergency backup power from a single integrated controller.
• Dual IP Protection Rating: Outdoor-rated IP55 cabinet enclosure withstands rain, dust, and direct sunlight exposure without additional shelter. Internal battery packs are individually sealed to IP67 for enhanced moisture and particulate protection, enabling deployment in coastal, desert, and high-humidity environments.
• Intelligent EMS Energy Scheduling: Built-in energy management system with configurable time-of-use schedules, dynamic load following, anti-backflow control, and demand response interface. Supports up to 5 cabinets in parallel for scalable multi-MWh installations within a single site network.

The GYC-ESS-125LC is purpose-built for commercial and industrial energy storage applications where reliability, rapid deployment, and low total cost of ownership are critical decision factors. Typical deployment scenarios include factory peak shaving and demand charge management, where the system shifts grid electricity consumption from high-tariff daytime periods to low-tariff nighttime hours, generating measurable electricity cost savings from the first month of operation. For solar PV self-consumption optimization, the cabinet captures surplus daytime generation that would otherwise be exported at low feed-in tariff rates and releases it during evening peak demand, significantly improving project ROI. In microgrid and off-grid island applications, the dual-mode inverter combined with the integrated EMS enables fully autonomous operation without grid reference, making the system suitable for remote mining sites, island communities, and telecom base stations where grid reliability is poor or non-existent. The cabinet also serves as a resilient backup power source for critical loads such as data center cooling, pharmaceutical cold storage, and semiconductor manufacturing clean rooms, providing sub-20ms transfer switching that prevents costly production interruptions.

Each GYC-ESS-125LC cabinet is shipped in a reinforced fumigation-free export wooden case with multi-layer EPE foam interior cushioning, ensuring structural integrity throughout ocean and land transportation. All battery modules undergo individual charge-discharge cycle testing with automated data logging before assembly. The complete system passes a 72-hour continuous full-load burn-in test at the factory, with test reports included in the shipment documentation package. We provide a 5-year standard product warranty covering manufacturing defects, with optional extended warranty plans up to 10 years available. Remote technical support via video call is included for the commissioning phase, and on-site commissioning engineer dispatch can be arranged for large-scale projects. Spare parts inventory is maintained in regional warehouses across Europe, Southeast Asia, and the Middle East for rapid response to any service requirements.
