Power Control Cabinets (PCC)

Every SelectCell battery system requires a Power Control Cabinet between the battery and the inverter.

Single PCC

The simplest configuration is a single PCC between the battery and the inverter. The PCC makes for a simple and neat installation.

  • 500A rated
  • 5x Battery Inputs with string fuses
  • 200kWh capacity as standard
  • 3x Inverter outputs fused
  • Disconnection Contactor
  • Precharge resistance circuit
  • Voltage & Current Sensor
  • Communications hub
  • Central Energy Management Unit
  • Dimensions (H x W x D): 1000 x 800 x 300 mm

 

Manager PCC plus Worker PCC

By attaching a manager cabinet with worker cabinet(s), the size of a system can be increased dramatically, while adding redundancy.

Manager features:

  • 1000A or 1500A rated
  • Up to 4 or 6 Worker PCC inputs
  • Up to 6 or 9 Inverter outputs, fused
  • Disconnection Contactors
  • Precharge resistance circuit
  • Voltage & Current Sensor
  • Communications hub
  • Central Energy Management Unit
  • Dimensions for 1000A (H x W x D): 1200 x 800 x 300 mm
  • Dimensions for 1500A (H x W x D): 1400 x 800 x 300 mm

Worker features:

  • 500A rated
  • 4x Battery Inputs with string fuses
  • 160kWh capacity as standard
  • 1x PCC Manager output fused
  • Disconnection Contactor
  • Precharge resistance circuit
  • Voltage & Current Sensor
  • Communications hub
  • Central Energy Management Unit
  • Dimensions (H x W x D): 800 x 800 x 300 mm

Advantages of adding Workers to Managers:

  • Larger systems, up to 960 kWh
  • More options for battery room layout
  • Dynamic Redundancy: Operating set points are automatically adjusted if parts of the battery bank needs to be disconnected, Worker PCC disconnects automatically and PCC Manager continues operating.
  • Each worker provides additional redundancy
  • Opportunity for future system expansion
