Product Summary
Engineered for high-throughput commercial and industrial (C&I) applications, the ST5015kWh-2500kW-MV-2h is a utility-grade, liquid-cooled Battery Energy Storage System (BESS). This integrated solution combines a massive 5 MWh energy capacity with a powerful 2.5 MW power rating, ensuring a reliable 2-hour discharge duration. As a direct wholesale supplier, we offer this turnkey solution with Tier-1 LFP cells, global shipping, and a comprehensive 10-year performance warranty, drastically lowering your Levelized Cost of Storage (LCOS).
Why C&I Sourcing Chooses ST5015kWh-2500kW-MV-2h (High ROI)
Procurement for large-scale commercial projects demands more than just hardware; it requires a bankable asset. The ST5015kWh-2500kW-MV-2h is designed to maximize demand charge reduction and energy arbitrage ROI. Its high 2-hour cycle rate is perfect for peak shaving in industrial parks, while the advanced liquid cooling ensures minimal degradation (first-year calendar aging < 0.5%). By sourcing directly from our manufacturing hub, you eliminate intermediary costs, securing a superior LCOE and faster project payback.
Product Overview & Safety Architecture
This system is built around an active safety architecture. At its core, Tier-1 prismatic LFP cells provide inherent thermal stability. The multi-layer Battery Management System (BMS) offers cell-level voltage and temperature monitoring, coupled with a NFPA 855-compliant aerosol fire suppression system. The IP55-rated outdoor cabinet houses the liquid cooling loop, power conversion system (PCS), and EMS controller in a single, compact footprint, simplifying installation and local maintenance (O&M) support.

Application Scenarios
EV Supercharging Stations & Solar PV Integration
The ST5015kWh-2500kW-MV-2h is the ideal backbone for high-speed EV charging hubs. It buffers low-cost off-peak energy or on-site solar PV, delivering 2500kW of burst power to support multiple 350kW ultra-fast chargers simultaneously, without straining the local grid. This turnkey PV-storage-charging solution guarantees predictable operational costs and unlocks new revenue streams for fleet operators and commercial landlords.
Supply Assurance & Global O&M
We back every unit with a digital supply chain protocol. Global delivery is supported via sea-freight compliant packaging (20ft/40ft HC containers) with real-time tracking. Our local O&M partner network provides 24/7 remote EMS dispatch and on-site service level agreements (SLAs), ensuring maximum uptime and performance guarantee fulfillment over the entire asset lifecycle.
Frequently Asked Questions
- What is the actual usable depth of discharge (DoD) for this system?
- The ST5015kWh-2500kW-MV-2h supports a 95% DoD, providing approximately 4764 kWh of usable energy per cycle, backed by our 10-year or 6,000-cycle performance warranty (whichever comes first).
- How does the liquid cooling system improve total cost of ownership?
- Liquid cooling maintains optimal cell temperature (25-35°C), reducing auxiliary power consumption by up to 30% compared to air-cooled systems. It directly extends cycle life and prevents thermal runaway, lowering long-term O&M costs.
- Can this BESS be paralleled for larger MW-scale projects?
- Yes, up to 10 units can be AC-parallel via the integrated EMS, scaling from 5MWh to 50MWh+ without complex re-engineering. The system supports standard Modbus TCP/IP for micro-grid controller integration.
- What certifications does the ST5015kWh-2500kW-MV-2h hold for international shipping?
- All units comply with UN38.3 for transport, and the assembled cabinet meets UL 9540, IEC 62619, and CE standards for grid interconnection in North America, Europe, and Asia-Pacific.
- What is the lead time for a wholesale order?
- For firm purchase orders (POs), our current lead time is 4-6 weeks FOB Shanghai/Tianjin. Expedited shipping options are available for projects under critical timelines. Contact our wholesale desk for a custom delivery schedule.
