1MW / 4MWh Microgrid Energy Storage System

1MW 4MWh Microgrid Energy Storage System

The 1MW 4MWh Microgrid Energy Storage System is designed for industrial facilities, remote power networks and hybrid energy projects that require reliable power conversion and flexible energy storage. The system combines a 1MW integrated power conversion and battery storage cabinet with an additional 2.058MWh air-cooled battery cabinet, providing a total nominal battery capacity of 4.116MWh.

Featuring lithium iron phosphate (LFP) batteries, a 400V AC power interface and an air-cooled enclosure design, this solution provides a flexible platform for industrial microgrids, renewable energy integration and backup power applications. Optional PV MPPT controllers, automatic transfer switching (ATS) and diesel generator interfaces can be configured according to project requirements.

Key Features

1. High-Efficiency Energy Management

Supports coordinated energy storage and renewable energy integration. Optional DC-coupled PV architecture can reduce conversion stages and improve overall system efficiency, subject to the final electrical design.

2. Integrated System Architecture

Combines power conversion and battery storage in an integrated cabinet, with an additional battery cabinet to increase total energy capacity. The modular configuration helps simplify project planning and equipment deployment.

3. Fast Power Transition

The specified system supports a grid/off-grid transition time of less than 20ms, subject to the complete system configuration and verified operating conditions. This feature can help support critical loads during changes in the power supply.

4. Flexible Microgrid Operation

Can be configured for grid-connected and off-grid applications, with optional solar PV, diesel generator and ATS integration. Operating modes and grid-forming functions depend on the selected PCS and microgrid controller.

5. Air-Cooled Battery Design

Uses an air-cooled battery enclosure with an IP54 system protection rating. The design supports simplified thermal management and is suitable for industrial energy storage projects where air cooling meets the site requirements.

6. Configurable Solar Integration

Optional external 120kW MPPT controllers provide a combined PV input capacity of up to 960kW based on the specified configuration. The final PV arrangement depends on DC voltage compatibility, string design and site conditions.

Typical Applications

  • Industrial microgrids and manufacturing facilities
  • Commercial and industrial energy storage
  • Solar PV and battery hybrid systems
  • Solar-storage-diesel microgrids
  • Remote mines and off-grid industrial sites
  • Weak-grid regions with unstable electricity supply
  • Backup power for critical industrial loads
  • Remote communities and island power systems
  • Renewable energy integration and power smoothing
  • Peak demand management and energy cost optimization, subject to local tariffs and operating strategy

System Configuration

The standard configuration consists of one integrated 1MW PCS and battery storage cabinet, together with one additional 2.058MWh battery cabinet. The combined nominal battery energy is 4.116MWh, while the rated PCS output remains 1MW.

Optional PV MPPT controllers, ATS equipment, diesel generator interfaces and an energy management system can be specified for individual projects. Before deployment, battery DC voltage compatibility, battery current limits, PCS operating modes, protection coordination and microgrid transition performance should be verified.
