Battery Discharge Test (only available on lead-acid batteries)
Configure the Battery Discharge Test settings in this section to either
manually or automatically perform a partial discharge test to gauge the
relative capacity of the external lead-acid battery. 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. This setting is only available
if the system is configured for use with a lead-acid type battery.
When the test is run, the output voltage from the power modules will be
reduced so that the external battery will power the system load until either
the "Set Discharge Time" limit or the "Set Discharge Voltage Limit" is
reached.
A
"Discharge Test Complete" notification indicates the battery can power
the connected load for the set test duration while maintaining its voltage
above the Discharge Voltage Limit. This notification is displayed on the front
display panel and is delivered via e-mail if messaging is configured via the
GUI (see Section 4.7.3).
The unit’s log (see Section 4.7.1) will record the completion of the discharge
test.
A "Discharge Test Failure" notification indicates the battery is unable to
power to load for the set duration.
The connected load devices should continue to run normally while the
discharge test is running.
NOTICE
This test must only be done when AC power is present during the
test and for adequate time after the test to allow for a full
recharging 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 for the test in minutes (10–
240 minutes) that the test will run. The default setting is 60 minutes.
Set Discharge Voltage Limit:
Minimum battery voltage which will
terminate the test. The default setting varies based on the power
modules installed.
