Configuring the Freedom SW using the SCP
Using the Low Battery Cut Out and
LBCO Delay Settings
The Low Batt Cut Out setting is the lowest battery voltage level
acceptable for use by the inverter. When the batteries discharge to the Low
Batt Cut Out setting, and are held at or below this level for the LBCO
Delay time, the inverter output shuts down and transfers any available AC
source (generator or grid) to the charger to bring the battery level back
above the Low Batt Cut Out setting. After shutdown, the inverter does
not support any AC loads, and AC loads must be powered by either a
generator or utility power.
• If using an automatic generator starting system, it is recommended to
set the Xanbus AGS voltage trigger setting higher than the Freedom
SW Low Batt Cut Out voltage.
• Although not recommended, if using an automatic generator starting
system with the start trigger set to the same voltage as the LBCO
voltage, do not set the LBCO Delay to less than the amount of time it
takes the generator to start and connect.
Otherwise – in both of the scenarios above – inverter output turns off before
the generator automatically starts, causing the battery voltage to recover
slightly. This may then stop the Xanbus AGS from starting the generator or
result in the Freedom SW cycling on and off multiple times before the
generator automatically starts.
Search Delay Search Delay sets the time between search pulses. When searching for
loads, the Freedom SW sends out search pulses to determine if a load
is present. If the Freedom SW finds a load above the Search Watts
setting, the inverter turns on. Freedom SW power draw while in search
mode decreases when Search Delay is increased, but the Freedom
SW’s response time to active loads is slower.
