High-Efficiency 241kWh/125kW Energy Storage Solution
In the rapidly evolving energy landscape, businesses are seeking more than just a battery; they need a reliable, high-return investment that secures their power supply while slashing operational costs. Our All-in-one Commercial ESS Cabinet (DT-E241WP-2A) is engineered to meet these demands, combining cutting-edge 314Ah LFP cell technology with a sophisticated air-cooled system in a single, compact footprint.
Designed specifically for Commercial and Industrial (C&I) environments, this integrated system serves as a powerhouse for peak shaving and load shifting. By discharging during peak tariff hours and charging when rates are low, the ECO-E241WP-2A provides a tangible Peak Shaving Energy Storage Solution that significantly reduces monthly electricity bills and optimizes your facility's energy profile.
Beyond cost savings, it functions as a robust Backup Power for Factories and data centers, ensuring seamless continuity during grid outages. Its agile deployment capabilities also make it the ideal candidate for Industrial Microgrid Battery Systems and remote off-grid projects.

Core Features & Technical Superiority
High-Density Energy Storage with 314Ah LFP Cells
At the heart of our cabinet is the next-generation 314Ah LFP Battery System. This high-capacity cell choice allows for a massive 241kWh energy capacity within a minimal $1.8m^2$ footprint. Unlike standard solutions, our system guarantees a Long Cycle Life of $\ge$ 8,000 cycles, ensuring your investment remains productive for over a decade.
Advanced Air-Cooled Thermal Management
Maintaining optimal cell temperature is critical for safety and longevity. Our Air-cooled Battery Storage System features an optimized ventilation design that limits cell temperature differences to $\le 6^\circ\text{C}$. This precision cooling ensures a stable 87% Round Trip Efficiency (RTE), even under heavy 0.5P charge/discharge cycles.
Engineered for Extreme Environments
Safety is non-negotiable. The cabinet is built to an IP55 protection level with a C4 anti-corrosion rating (C5 optional), making it resilient against dust, rain, and salt mist. With a wide operating temperature range of $-25^\circ\text{C}$ to $55^\circ\text{C}$ and full performance up to 3000m altitude, it is truly a "place anywhere" solution for global EPC contractors.
FAQ
Q: How does the 0.5P C-rate benefit a commercial user compared to a 0.25P system?
A: A 0.5P rate means the system can fully charge or discharge in 2 hours. For **Peak Shaving** applications, this allows the battery to cover the entire peak tariff window effectively, maximizing your electricity savings and ROI.
Q: What fire suppression protocols are integrated into the cabinet?
A: Safety is multi-layered. We use a combination of smoke and temperature sensors linked to an automatic **Aerosol fire suppression system**. Additionally, the BMS provides active protection by isolating strings at the first sign of abnormal thermal behavior.
Q: What exactly is included in the "All-in-one" configuration?
A: It is a "Plug & Play" solution. The cabinet integrates the battery modules, BMS, **125kW PCS**, smart power distribution, HVAC, and fire suppression. It arrives pre-configured and factory-tested, requiring only AC cabling on-site.
Q: The footprint is only 1.8$m^2$. Are there specific foundation requirements?
A: Due to the weight (2,670 kg) and high energy density, a level reinforced concrete pad is required. However, because of its **IP55 rating**, it does not require a dedicated building and can be installed outdoors to save indoor floor space.
Q: Does the system meet European or North American grid-entry standards?
A: Yes. The system is compliant with **IEC 62619, IEC 63056, and EN 50549-1/2**. These certifications ensure the system is recognized by global utilities for safe grid connection and power quality.
