WARNING
Use the Equalize Charge setting for flooded lead-acid batteries in a well-
ventilated location only.
Do not use Equalize Charge on sealed batteries!
Configure the
Battery Discharge Test
to check on the battery’s ability to power
the system for a set duration. Set Max Discharge Time, minimum Stop Voltage,
and the automatic repeat Interval if desired. Each time 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 Max Discharge Time limit or the Stop
Voltage 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 Stop Voltage is hit before the Max Time limit, as the battery
was not able to power the load for the desired duration.
A Battery Discharge Test of a fully charged battery can be manually initiated by
changing the discharge test Status parameter to
Enabled
.
