The Victron Energy ASS030066301 RJ12 UTP Cable is a genuine Victron communication cable designed to connect the shunt of a compatible BMV battery monitor to its BMV head unit. It provides a factory-terminated replacement cable for installations where the standard BMV connection does not suit the required equipment layout. 

Using UTP (Unshielded Twisted Pair) construction with RJ12 connectors at both ends, the cable provides a ready-to-use connection without requiring field termination. It is particularly useful when the battery bank and measurement shunt are installed well away from the preferred location of the BMV display. 

Key Technology

• BMV Shunt-to-Head Unit Connection
  Designed specifically for the communication connection between a compatible Victron BMV battery-monitor shunt and its display/head unit.

• RJ12-to-RJ12 Connectivity
  Factory-installed RJ12 connectors at both ends provide a direct plug-in connection for supported Victron BMV monitoring equipment.

• UTP Construction
  Uses unshielded twisted-pair construction for the BMV communication connection.

• Factory-Terminated Design
  Pre-installed modular connectors eliminate the need for field crimping or custom cable termination.

• Flexible Monitor Placement
  Allows the BMV shunt to remain near the battery bank while the corresponding head unit can be installed at a more convenient monitoring location.

• Genuine Victron Replacement
  Victron offers RJ12 UTP cables in multiple lengths so the standard cable supplied with a BMV battery monitor can be replaced when a different routing distance is required. 

Best Uses

• Victron BMV Battery Monitors
  Ideal for connecting the shunt and head unit in compatible Victron BMV battery-monitoring systems.

• Remote BMV Display Placement
  Useful when the battery bank and shunt are located away from the preferred viewing position of the battery-monitor display.

• Replacement Communication Wiring
  Suitable for replacing a damaged, incorrectly sized, or unsuitable BMV RJ12 communication cable.

• Battery Energy Storage Systems
  Provides the dedicated BMV communication connection in compatible battery-based solar and energy-storage installations.

• System Reconfiguration
  A practical option when relocating a compatible BMV head unit while retaining the shunt near the battery bank.
