FGI 125kW/261kWh Liquid-Cooled Commercial & Industrial Energy Storage System: Unlock Peak Power Quality, Maximize Generation & Expand Grid Capabilities




  • Peak Shaving and Valley Filling (Load Leveling):

​Achieve reduced electricity costs and balanced grid load by charging energy storage systems during periods of low grid demand (valleys) and discharging during peak demand periods (peaks).​

  • Emergency Power to Prevent Significant Economic Losses from Sudden Power Outages:

​Serve as a reliable backup power source during main power interruptions, preventing substantial economic losses such as critical equipment downtime, data loss, and production halts caused by sudden power failures.





Overview


  • Integrated Design: This 125kW/261kWh liquid-cooled industrial and commercial energy storage system adopts an "All In One" design, integrating battery PACK, BMS, PCS, EMS, thermal management, and fire suppression into a standardized cabinet.
  • Modular and Scalable: The system is modular and standardized, allowing for easy expansion through parallel connection of multiple cabinets.
  • High Performance Attributes: It incorporates advanced technologies emphasizing high efficiency, high safety, long lifespan, and ease of expansion.
  • Plug-and-Play Functionality: A single cabinet forms a complete and independent system that is easy to install and operate.
  • Flexible Deployment: The system is suitable for various user-side applications, including industrial and commercial parks, low-voltage distribution stations, highway service areas, gas stations, and airports.
  • Versatile Application Scenarios: It supports expanded applications such as integrated photovoltaic storage and charging, and microgrids.
  • Multiple Operating Modes: The cabinet supports various operating conditions, including peak-valley arbitrage, anti-backflow, demand control, load tracking, and backup power supply.
  • Intelligent Cloud Management: The system features intelligent cloud maintenance, enabling multi-level authority management, custom data reports, and tailored fault alerts.

Main Functions

  • Real-time Data Monitoring: Tracks energy generation, storage, consumption, and collects detailed data from components like the battery (charge/discharge, temperature, voltage, current).
  • Intelligent Energy Control: Optimizes charging and discharging based on real-time demand, grid conditions (price, load), and planned schedules.
  • Proactive Fault Management: Detects and alerts on potential issues (over-charge/discharge, temperature anomalies) to ensure safe operation. Enables remote control and protection via grid integration.
  • Cloud-Based Remote O&M: Uploads operational and fault data to the cloud for remote fault prediction and diagnosis, simplifying maintenance.
  • Benefit Visualization: Displays energy storage benefits and power information.
