A Nuvation Energy BMS Fault indicates the state of the battery system has been detected
outside of its safe operational range. The cause of the fault must be identified and a
corrective action must be performed. For instance, if the fault is a cell voltage
measurement has become too low, the cell maintenance manual must be reviewed to
identify what remedial actions are required.
A Nuvation Energy BMS Fault is more severe than a Nuvation Energy BMS Warning and
the source of the fault must be discovered and resolved before attempting to clear
Nuvation Energy BMS Fault to continue operating the battery system.
An ALL OK indicates that there are no faults or warning. This is the normal state for
Nuvation Energy BMS.
7.1.3. Stack Voltage
The stack voltage radial meter shows the total battery stack voltage.
Refer to the Stack Voltage Thresholds section in the
Software Reference Manual
to tune this gauge
7.1.4. Stack Current
The stack current radial gauge shows the battery stack current as well as the maximum charge
current limit and the maximum discharge current limit. The acceptable current range is visualized on
the gauge by the blue arc. An absence of the blue arc indicates the battery stack cannot be charged
or discharged in its present condition.
A negative current value indicates the battery stack is charging. A positive current value indicates the
battery stack is discharging.
