Description
Key Features
-
Intelligent Liquid Cooling: Advanced liquid-cooling thermal management ensures the temperature difference between cells remains minimal. This extreme temperature consistency prevents premature degradation, extends the battery to over 8,000 cycles, and drastically reduces parasitic energy consumption compared to standard HVAC cooling.
-
All-in-One Extreme Integration: A fully integrated powerhouse. Housed within the cabinet are the Batteries (BAT), PCS, BMS, EMS, Fire Protection, Liquid Cooling, and Power Distribution. It even supports optional in-cabinet PV DC modules (up to 4 MPPTs), STS on/off-grid switches, and Isolation Transformers, providing a complete microgrid solution in a box.
-
Massive Output & Capacity: Powered by next-generation 314Ah cells. The ESG-M241 offers 120kW / 241kWh, while the ESG-M261 provides 125kW / 261kWh. Designed for heavy 0.5C charge/discharge rates.
-
Triple Fire Protection System: Safety is uncompromising. It features a three-tier defense mechanism: Gas Detection + Aerosol Fire Suppression + Water-Based Firefighting, effectively neutralizing thermal runaway risks before they escalate.
-
IP55 Outdoor Durability: Built to withstand the elements, the heavy-duty enclosure operates flawlessly in harsh outdoor environments from -25°C to 60°C, eliminating the need for expensive climate-controlled indoor battery rooms.
-
C&I Scalability (Up to 2.6MWh): Modular and highly scalable. Up to 10 cabinets can be paralleled, allowing businesses to scale their energy storage from 241kWh to over 2.6MWh seamlessly as their operational needs grow.
-
Cloud-Based EMS & AI Analytics: Equipped with advanced local control and cloud platforms. Features self-learning AI algorithms for Remaining Useful Life (RUL) prediction, automatic fault localization, and intelligent balancing.
Applications
-
Commercial Peak Shaving: Perfect for factories and large facilities to avoid crippling peak-demand utility charges.
-
Microgrid & Off-Grid Mining: Integrates seamlessly with diesel generators and massive solar arrays to power remote industrial operations.
-
EV Charging Hubs: Provides the massive surge power needed for multi-bay DC fast-charging stations without crashing the local grid.
