battery will power the system load until either the Max Discharge
Time limit or the minimum Discharge Voltage Limit is hit. A
Discharge Test Complete notification (on the front display and with
an e-mail if messaging is configured via the Network GUI) will
indicate a Test Failure if the minimum Discharge Voltage Limit is hit
before the Max Time limit, as the battery was not able to power the
load for the desired duration. You should generally limit the depth of
discharge to no more than 50% of the nominal battery capacity to
avoid stressing the battery due to a deep discharge.
NOTE:
This test must only be done when AC power will be present during the
test and for adequate time after the test to allow for a full re-charging
of the battery. Otherwise the battery may not have sufficient remaining
capacity to power the load during an AC power outage.
Set Discharge Time: Set the maximum time duration (in
•
minutes) for the Discharge Test.
Set Discharge Voltage Limit: Set the minimum Discharge
•
Voltage Limit. If this Voltage Limit is hit before the Max
Discharge Time limit, the test will fail, as the battery was not
able to power the load for the desired duration.
Discharge Test Interval: Set the Discharge Test Interval
•
(days) to have the system automatically initiate a discharge
test every interval, once the battery reaches 100% SOC. Set
this interval to 0 days to disable the automatic Discharge
Test (default setting). NTP Time Synchronization must be
enabled on the Communications Basic Setup page to enable
automatic Discharge Tests.
Start Time: Set the time of day for automatic Discharge
•
Tests to start. The time of time must be entered using 24-
hour time format. NTP Time Synchronization must be
enabled on the Communications Basic Setup page to enable
automatic Discharge Tests.
You may alternatively manually initiate a Battery Discharge
Test of a fully charged battery by clicking on the Manual
Discharge Test button. (The status box will show that the
discharge test is Not Ready if the battery SOC is less than
100%)
