setting should be set to the value recommended by the battery
manufacturer.
LVD Settings
Disconnect Voltage:
Enter the battery low voltage disconnect voltage
threshold to a level that will protect the battery from excessive discharge
(default is 10.5/21/42V). The LVD contactor will open when the battery
discharges to this level for at least 3s.
Reconnect Voltage:
Enter the reconnect voltage to a level at least 1.5V more
than the disconnect voltage to prevent the LVD contactor from repeatedly
cycling on and off. This setting will be used when charging the battery from
an external DC source (such as a solar system), otherwise once AC power
returns the LVD contactor will automatically close so that the power modules
can charge the battery directly.
Battery Over-Current Alarm
Over-Current Threshold:
Enter the system output over-current threshold to
receive an alarm notification when the battery discharge or charge current
exceeds a set over-current level. Set the threshold to 0A to disable this alarm
(default setting).
Alarm Reporting
Activate Alarm Form C Contact:
Check this box (default) to have the back
panel alarm contacts change state for an alarm condition.
Send E-mail:
Check this box to have an alarm e-mail sent to the e-mail
address(es) set up in the
Communications E-MAIL SETUP
page.
For Battery Management Modules with dual battery breakers (BMMD
version), select the
Ignore Circuit Breaker 2 Status
check box if the system is
used with a single battery string and the BAT 2 terminal is unused. This will
mask the open circuit detection for battery breaker 2, to prevent false alarms
if the breaker is left open on the unused channel.
Battery Backup (with optional BMM - Lead Acid Batteries only)
The following additional settings are only available if the system is configured
for use with a lead-acid type battery:
Output Voltage Control
Temperature Coefficient / cell:
Select the temperature coefficient per cell
that matches the battery manufacturer
’
s recommended compensation value
in order to keep the battery in good state of health by optimizing the
automatic control of the battery charging voltage. This value will typically be
-4mV/°C (-24mV/°C for a 6 cell 12V battery) for a flooded lead-acid battery
