Batteries
The battery section of the page shows various status characteristics of the battery reserve
system configured for the system. The following items are provided:
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 calculated. Specific battery models included in the
standard or custom controller configurations have default AH values.
AH rates are 8-hour rates. These values can be modified in the field as
needed. Values are used for battery capacity calculations when
discharge data is not available.
Online Capacity Capacity sum of all batteries installed in the system and are able to
provide power in the event of an AC failure. Batteries taking removed
from the system using a contactor are considered not to be online.
State Of Charge The relative state of charge in % of rated battery capacity
approximation of the battery string. Calculation is based upon coulomb
counting techniques.
Total Current Measured value of the current flowing into or out of all system battery
shunts.
On Discharge The direction of current flow in and out of the batteries. “Yes” when
being discharged and “No” in normal state.
Model The specific battery model or Generic class of battery configured to be
installed in the system.
Number Of Strings The total number of battery strings installed in the system. This value
needs to be configured unless provided in custom default configuration.
Reserve Time Provides the controller calculated reserve time for the batteries installed
in the system based upon discharge data or coulomb counting
techniques (hh:mm). Note: may also display “LOW CURRENT” or
“HIGH CURRENT” if the values of current are not consistent with the
system capacity.
Highest Highest battery temperature being measured by the QS871 thermal
