BCS Solution


A complete battery control solution that is scalable for commercial and industrial applications

The BCS Solution

  • Real-time signal processing
  • CAN interface
  • MODBUS TCP signal interface


A single BCS unit can manage and control up to 100 batteries. Typical setups uses 2, 4, 16 or 24 batteries.

Connection Topologies

400V (1sXp) and 800V (2sXp) connection modes are possible.

Ease of Operation

Ease of Operation

With the BCS HMI view your connected batteries, run diagnostics, set system controls.
