Engineered for heavy-duty commercial, industrial, and remote off-grid applications, our 2.5MW / 6.25MWh Microgrid Energy Storage System integrates a high-performance 2.5MW / 690V Power Conversion System (PCS) with a state-of-the-art 6.25MWh liquid-cooled battery cabinet. Designed with supreme flexibility, the system natively supports additional photovoltaic (PV) ATS and diesel generator interfaces, delivering seamless multi-source coordination, superior efficiency, and uninterrupted power supply (UPS) capabilities in any environment.
Key Application Scenarios
- Remote Mines & Quarries: Provides robust, reliable 24/7 off-grid power to heavy machinery and camp facilities where grid connection is unavailable or prohibitively expensive.
- Ports & Marine Terminals: Powers high-demand logistical equipment, electric cranes, and shore-power facilities with rapid load response and grid-forming stability.
- Industrial Parks & Manufacturing Plants: Acts as a peak-shaving, load-shifting, and backup power unit to lower electricity bills and prevent costly production downtime.
- Island & Isolated Microgrids: Combines PV, diesel generators, and energy storage into a unified green microgrid to maximize renewable penetration and energy independence.
- Commercial Complexes & Data Centers: Ensures ultra-reliable emergency backup and power quality improvement against sudden grid outages.
Core Product Features (Extracted & Translated from Design Specs)
1. 8%+ Efficiency Boost (Higher Energy Yield)
- Direct DC PV Storage: Enables localized PV direct current storage, skipping two-stage AC/DC conversions and eliminating double-transformer losses. Charging efficiency is enhanced by over 8% compared to traditional AC-coupled systems.
2. Lower System Cost (CAPEX Reduction)
- Streamlined Architecture: Eliminates the need for traditional PV inverters and independent step-up transformers, reducing transformer and ring main unit (RMU) costs by approximately 50%.
3. 24/7 Uninterrupted Power Supply (All-Weather Reliability)
- Lightning-Fast Switching: Supports off-grid/on-grid switching in under 20 milliseconds (<20ms), ensuring seamless 24/7 uninterrupted power for critical industrial sites, mines, and ports.
4. Multi-Mode Intelligent Control (Strong Grid-Forming Capability)
- Four-Quadrant Operation: Offers flexible inverter operating modes including VSG (Virtual Synchronous Generator), PQ, and VF control, delivering exceptional grid-forming capabilities and high system stability under weak-grid or isolated conditions.
