1500V Centralized Energy Storage System Solution

1. Independent/shared energy storage power station: 50MW/100MWh, 100MW/200MWh and GW energy storage power stations, etc.
2. Supporting energy storage for Wind-PV power stations: supporting energy storage projects for PV power plants/wind farms, such as 5MW/10MWh, 10MW/20MWh and above
3. Energy storage system for industrial and commercial parks: 2.5 MWh and above 10kV/35kV grid-connected energy storage system for industrial and commercial parks

Overview

At present, the scale of a single energy storage power plant is gradually expanding. For example, 100 MW and GW-level power plants have become the dominant trend, while the traditional 1000V energy storage system has pain points such as high cost, large floor area and low combined efficiency; CYG ET adapts to the market trend and delivers the 1500V centralized energy storage system solution, which can reduce the system power consumption cost by about 10%. 

  CYG ET provides integrated project services, including: 

  • For the 1500V liquid cooling integrated solution, the scale of a single energy storage unit is 3MW/6MWh (3.35 MW/6.7MWh), which consists of two 3MWh (3.35MWh) liquid-cooling battery tanks and one 3MW (3.35MW) integrated boost inverter 

  • For the 1500V air cooling integrated solution, the scale of a single energy storage unit is 2.5MW/5MWh, which consists of one 5MWh air-cooling battery tanks and one 2.5MW  integrated boost inverter 

  • 1500V integrated boost inverter, such as 2.5MW, 3MW, 3.15MW, 3.35MW integrated boost inverters (power can be customized) 

  • 1500V energy storage converters, including 1250kW, 1500kW, 1575kW, 1675kW and 1725kW energy storage converters 

  • Monitoring and control equipment such as energy management system 

  • EPC and power plant operation and maintenance services
