50 Freedom SW Owner’s Guide
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.
