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.
Hi Batt Cut
Out
Hi Batt Cut Out sets the maximum battery
voltage at which the inverter will operate. If the
battery voltage exceeds this limit for more than
one minute, the Freedom SW displays a fault
message and shuts down. The inverter will not
support AC loads when in this condition. If a
qualified AC source is present, the unit passes
AC through to the loads. The inverter
automatically restarts when the voltage drops to
1.5 volts (12 volt system) or 3 volts (24 volt
system) below the
Hi Batt Cut Out
setting. If
battery voltage continues to rise after shutdown,
an external charger may still be charging the
batteries. The Freedom SW cannot control how
external chargers operate.
Search
Watts
Search Watts sets the Freedom SW’s search
sensitivity when search mode is enabled. When a
load larger than this setting is present, the inverter
starts producing AC output. Enabling search
mode from the
Setup
menu (see page 57) can
minimize power draw from the battery during
periods of low demand from loads. Also see
“Using Search Mode” on page 45.

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.
