BCS-A Series 50~500kVA

Three-phase

Energy Storage Converter


BCS50K-A/BCS100K-A/BCS250K-A/BCS500K-A

  • Key Features
  • Technical Data
  • Related Solutions

Battery Management:

With bidirectional converter to charge or discharge batteries
Optional modes for charging, including  pre-charging, constant current charging, equalized charging and floating charging
Discharging can be realized in modes of either constant power discharging or constant current discharging


Power Grid Adaptability:

Meeting the smart grid design specification and allowing power grid dispatching
Advanced islanding detection technology
Reactive power compensation and other functions
Off-Grid independent operation 



System Characteristics:

• Completely isolation of batteries from the power grid
Smart interface and communications
Charging and discharging time setting for 16 segments, better for customer's on-site applications
On/off grid switching time: general conditions <200ms; zero transition can be achieved under specific conditions (external connection of SCR)
Four periods of time (peak, flat, valley and sharp) price setting, flexible calculation of user profitability
