261kWh Liquid-Cooled All-in-One ESS Cabinet
In today's volatile energy market, a reliable industrial battery backup is no longer a luxury-it's a strategic necessity. D.T. Multi Tech introduces the next generation of Commercial & Industrial (C&I) energy storage solutions: an All-in-one Liquid-cooled ESS Cabinet designed to provide seamless power resilience, peak shaving, and optimized self-consumption for high-demand environments.
Why Choose Liquid Cooling for Your Industrial Backup?
Unlike traditional air-cooled systems, our liquid-cooled ESS utilizes advanced thermal management to maintain a uniform temperature across the 314Ah LFP cells. This technology limits the temperature difference between cells to within 3°C, significantly extending the system's cycle life to > 8,000 cycles. For industrial users, this translates to a much lower Levelized Cost of Storage (LCOS) and enhanced safety under continuous 0.5P charge/discharge rates.

Core Powerhouse
As the energy hub of the entire system, the DT-E261LP-2A represents the cutting edge of Commercial & Industrial (C&I) energy storage evolution. Its core competitive advantage lies in "extreme thermal management," which ensures a superior long-term Return on Investment (ROI):
Pack-Level Liquid Cooling: Moving beyond traditional cabinet-style air cooling, this model features an advanced liquid-cooling manifold design that maintains cell-to-cell temperature differentials within 3°C. This uniform thermal environment effectively prevents premature capacity degradation, boosting the cycle life to over 8,000 cycles. For plant operators, this directly extends the project's operational lifespan and significantly lowers the Levelized Cost of Storage (LCOS).
High-Density Integrated Design: The 125kW/261kWh configuration strikes a precise balance between energy density and power output. This compact footprint allows small-to-medium factories and commercial centers to deploy robust peak shaving and backup power capabilities even where space is at a premium.
FAQ
Q: Why should I choose liquid cooling over traditional air cooling for a 261kWh cabinet?
A: Liquid cooling provides superior thermal uniformity. By maintaining a cell-to-cell temperature difference of ≤ 3°C, we prevent "hot spots" that lead to premature battery degradation. This technology extends the cycle life by approximately 20% compared to air-cooled systems, ensuring a higher ROI over the system's 10-15 year lifespan.
Q: Can the 125kW PCS handle inductive loads like large industrial motors?
A: Yes. The integrated PCS is designed for industrial environments and can handle brief surge currents. For specific high-torque motor starting requirements, we can assist in calculating the starting kVA to ensure the 125kW rating is sufficient for your peak startup demand.
Q: Can I parallel multiple 261kWh units for a MW-scale project?
A: Absolutely. The system supports multi-unit parallel expansion on both the DC and AC sides. Our STS and EMS (Energy Management System) are designed to coordinate multiple cabinets as a single unified power plant.
Q: What maintenance does the liquid cooling system require?
A: The liquid cooling system is a closed-loop design. It requires a simple coolant level check and a visual inspection of hoses once a year. The coolant typically only needs replacement every 5 years depending on the environment.
Q: Do you provide on-site commissioning support for international projects?
A: We provide comprehensive remote commissioning support via video and real-time data monitoring. For large-scale projects, we can deploy a technical team to your site for final commissioning and staff training.
