If Lithium-Ion type battery is selected, it must utilize an integrated battery
management system (BMS) to protect the battery cells from inappropriate
voltage or current levels.
Configure the
Battery Type
of the battery used in the system (Lead-Acid or
Lithium-Ion). If Lithium-Ion type battery is selected, the following battery
parameters and settings will be unavailable: Battery State of Charge, Run-time
Remaining, Voltage Temperature Coefficient / cell, Equalize Charge, and Battery
Discharge Test.
Adjust the
LVD
contactor
Disconnect
and
Reconnect
Voltage
according to the
battery manufacturer’s recommendations
.
Set the
Battery Charge Current Limit
to limit the maximum battery charge
current provided, while still allowing the full rated current to be drawn from the
main output.
Set the
Battery Overcurrent
Alarm level (Amps) to trigger an Alarm for excessive
discharge current or charge current (set to 0A to disable this alarm).
Configure the combined
Battery Capacity
(Ahr) so the system can estimate the
total battery SOC%. Also set the
Battery Rate
(hrs) used in the battery
specification to determine the battery capacity. (Usually will be 20hr or 10hr rate)
Series connected batteries have the Ahr capacity of a single battery, while
connecting batteries in parallel increases the total Ahr capacity.
BMM Settings (Lead-Acid Batteries only):
The following additional settings
are only available if the system is configured for use with a lead-acid type
battery:
Set the
Low SOC Alarm
(%) if desired, to raise an alarm when the battery is
nearly discharged.
Ensure the Battery temperature sensor (ICT-TMP) is installed and connected to
the battery case (see
Make sensor and Alarm Connections
in the Installation
section) for optimal Lead-Acid battery charging and best battery life. Set the
Temperature Compensation/°C
level per battery cell to match the
recommendation of the battery manufacturer (-4mV/°C per cell typical).
Configure the
Battery Equalize Charge
voltage, duration, and automatic repeat
interval if desired when using flooded lead-acid type batteries only. The system
will step up the output voltage to the Equalize Voltage for the Equalize Duration
time whenever the Equalize Status is set to Enable.
