Configuring the Freedom SW using the SCP
Follow procedures on “To select and change a configurable setting:” on
page 33 to change the settings.
Using Search Mode
Why use Search mode? Search mode allows the inverter to selectively
power only items that draw more than a certain amount of power, which can
result in power savings. The Freedom SW has a no-load power draw of
about 28 watts. Enabling search mode reduces this power draw to less than
8 watts. Search mode operates differently in single-unit and multi-unit
installations.
Single units When a single Freedom SW has search mode enabled, the
inverter sends electrical search pulses through its AC output. These search
pulses look for connected AC loads. The delay between search pulses is set
using the Search Delay setting. After a load larger than the Search
Watts setting is detected, the inverter starts producing AC output.
Multiple units When configured for 120/240-volt series stacking, each
inverter/charger operates independently in search mode and attempts to
detect loads connected to its terminals only.
To use search mode in parallel stacking, the Master unit must have Search
Mode disabled. The Slave unit must have Search Mode enabled.

Configurable Settings
Item Description
Inverter Enables or disables the inverter function of the Freedom SW. When
enabled, the unit will invert power from the batteries assuming there
is enough charge in the batteries.
Default value is Enabled.
Search Mode Enables or disables the Search Mode function of the Freedom SW.
See “Using Search Mode” on page 34 for more information.
Default value is Disabled.
Charger Enables or disables the charger function of the Freedom SW. When
enabled, the unit will charge the batteries when AC is available. For
more information on configuring the charger settings go to “Charger
Settings Menu” on page 48.
Default value is Enabled.
Auto Chg Enable Forces the Freedom SW to charge the batteries when qualified input
AC is detected even when the charger function is disabled.
Equalize Initiates the battery equalization process. See “Equalization
Procedure” on page 36 to enable the procedure.
Default value is Disabled.
Desired Mode Switches between Operating and Standby modes.
Default value is Operating.
Clear Faults
Warning
Clears any active faults and warnings.
Basic Settings See “Changing Freedom SW Basic Settings” on page 37 for more
information.
Advanced Settings See “Charger settings in a Dual Freedom SW configuration ” on
page 40 for more information.
IMPORTANT:
The Slave unit continuously monitors the output of the
Master unit. If the Master unit has more than 60% of the rated load (e.g.,
1800 watts on Freedom SW 3012), the Slave unit will assist the Master and
the two will share the load equally. Should the load on the Master drop
below 20% of rated load (600 watts for Freedom SW 3012), the Slave unit
disengages and returns to a waiting state.
