A 2.5MW / 12.5MWh microgrid energy storage solution featuring a 690V power conversion system and two 6.25MWh liquid-cooled battery units. Designed for industrial microgrids, renewable energy integration, backup power and off-grid applications, with optional PV, ATS and diesel generator integration

2.5MW 12.5MWh Microgrid Energy Storage System

The 2.5MW 12.5MWh Microgrid Energy Storage System is designed for industrial facilities, remote power networks and renewable energy microgrids requiring reliable, flexible and efficient energy management. Featuring a 690V power conversion system (PCS) and two 6.25MWh liquid-cooled battery units, this solution combines large-scale energy storage with flexible microgrid integration.

With a configurable system architecture, the solution can support solar PV generation, battery storage, diesel generators and automatic transfer switching (ATS), subject to project-specific engineering. It is suitable for off-grid power supply, weak-grid support, renewable energy integration and backup power applications.

Key Benefits

  • Higher System Efficiency: DC-coupled PV integration can reduce conversion losses and improve overall system efficiency by 8% or more in suitable configurations.
  • Lower System Cost: An integrated architecture can reduce the need for separate PV inverters and step-up transformers, potentially lowering system costs by up to 50% in applicable project configurations.
  • Seamless Power Transition: Supports transfer times below 20ms where the selected PCS, controller and switching architecture meet the required specifications.
  • Flexible Operating Modes: Supports configurable grid-forming VSG, PQ and VF operating modes, with four-quadrant power control subject to system configuration.
  • Renewable Energy Integration: Enables coordinated operation of solar PV, battery storage and diesel generation for improved energy utilization.
  • Scalable Microgrid Design: Provides a flexible platform for industrial microgrids, remote power systems and critical-load power supply.

Typical Applications

  • Industrial parks and manufacturing facilities
  • Remote mines and off-grid industrial sites
  • Solar-plus-storage-diesel hybrid microgrids
  • Weak-grid areas with unstable electricity supply
  • Commercial and industrial backup power
  • Renewable energy integration and energy management
  • Island and remote community electrification

The system can be configured according to project requirements, including PV capacity, diesel generator ratings, ATS arrangements, load characteristics and microgrid control strategies. Final performance, switching time and system efficiency depend on the selected equipment and site conditions.
