Battery Monitoring Option


HB5 battery monitoring module adds battery monitoring and low battery voltage disconnect capabilities. It protects the battery by disconnecting the load from the battery when the battery voltage is below a critical setpoint value (voltage settpoint fully adjustable). The following monitoring and alarming features are included in this option, in addition to the standard monitoring and alarming features standard in HB5.

Additional Monitoring


  • Load voltage
  • Battery voltage
  • Midpoint 1 voltage
  • Midpoint 2 voltage
  • Current
  • Battery charge/discharge

Additional Alarming


  • Low battery voltage
  • Midpoint 1 battery voltage imbalance
  • Midpoint 2 battery voltage imbalance
  • Battery fuse open
