Configuring the Freedom SW using the SCP
Inverter Settings Menu
The Inverter Settings menu contains settings that control when
the Freedom SW starts and stops producing AC output.

Table 9 Inverter Settings Description
Item Description
Low Batt Cut Out Low Battery Cut Out (LBCO) controls when the inverter stops
producing AC output due to a low battery voltage condition. The
inverter will stop producing AC output only after this level has been
reached for the period of time set by the LBCO Delay. This setting is
not temperature compensated.
LBCO Delay LBCO Delay controls how long the inverter is allowed to operate at or
below the Low Batt Cut Out level before turning off due to a low
battery voltage condition. The inverter will stop producing AC output
only after the Low Batt Cut Out level has been reached for this
uninterrupted period of time.
Once the inverter has shut off, the battery voltage must rise 2 volts
above the Low Batt Cut Out setting (4 volts for 24-volt systems) for
inverter operation to resume.
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 39.
