Batteries

Table 13 Batteries Status

Installed Capacity

Total installed battery capacity based upon the number of strings in the system
and the Amp-Hour (AH) rating of the strings installed. This data is automatically
entered for specific battery models included in the standard controller
configuration. These values can be modified in the field. AH rates are 8-hour
rates.

Number Of Strings

The total number of battery strings installed in the system.

Current

Measured value of the current flowing into or out of the batteries.

Highest Temp

Highest battery temperature being measured by the QS871 thermal probes
attached in the system.

Num Temp Probes

Total number of installed QS873A thermal probes. Up to sixteen QS873A probes
can be monitored by the controller.

Num Mid-String V

Total number of installed ES771 Mid-String voltage measurement modules. Up
to six ES771 modules can be monitored

Mid-String V
Monitor

Measured values of ES771 Mid-string voltages attached in the system. Up to
three mid-string voltage readings per module.

Battery Test Result

Shows whether the most recent battery test was completed, and the last
calculated reserve time.

Next Test

The date of the next automatic battery discharge test. The automatic discharge
test feature must be enabled for this to work.

Shunt Currents

Table 14 Shunt Currents Status

Plant Shunt

Displays the value of current measured by the shunt monitor on-board the
controller. The plant shunt type must be set to Load or Battery and its current
rating must be configured. Shunts are assumed to have a 50mV rating. Note:
The Plant Shunt is generally used for a centralized architecture where there is
one shunt for load or battery in which all the current passes.

ID1-8

Displays the individual shunt monitor currents measured by attached and
properly configured Distribution Control and Monitoring modules. Values may
be specific load or battery currents. Distribution Control and Monitoring
modules include the NE872 and QS871. Up to eight values can be displayed.

Disconnect States

Table 15 Disconnect States Status

LVBD(1)

Provides LVBD (Low Voltage Battery Disconnect) status. “None” is displayed for
each non-configured contactor. “Closed” is shown for normal contactor state.
“Open” shown for contactors that have opened and disconnected the battery.

LVLD(1-3)

Provides status of the three LVLDs (Low Voltage Load Disconnects 1-3). “None”
is displayed for each non- configured contactor. “Closed” is shown for normal
contactor state. “Open” will be shown for contactors that have opened or
disconnected each respective load.
