Xantrex Freedom SW 3,000 Watt True Sine Wave
Inverter Operation (Model: FSW3012)
This article provides basic operation instructions for a Xantrex Freedom SW 3,000 Watt True Sine Wave Inverter (Model:
FSW3012).
The Freedom SW Inverter/Charger is a true sine wave
inverter/charger that can be used for mobile, marine
and commercial applications. The Freedom SW Inverter/
Chargers are designed to operate with a wide variety of
generators and are capable of operating in parallel with a
generator for short durations to assist with starting large
loads. The Freedom SW is a convenient combination of
an inverter, multistage battery charger, and transfer switch
in one electronic device.
Inverter Operation Using The
Front Panel
Once the inverter/charger is installed, you can operate it
in invert mode. To operate in invert mode from the front
panel:
1. Press the INVERTER ENABLE button on the Freedom
SW on the front panel. The INVERTER ENABLED LED
turns on and connected loads will be energized.
2. Note that if AC is present and being passed through,
the INVERTER ENABLED LED will still turn on to
indicate inverter mode has been enabled. However,
AC will continue to be passed through to the loads
until conditions exist that cause AC to be disqualified,
in which case the unit will transition to invert mode
and power up critical loads.
3. Connect AC input power. The charger automatically
starts up when qualified AC power is connected.
4. Disconnect AC power from inverter input by opening
the breaker or disconnect.
5. Place a load on the inverter. For example, plug a
100-watt light bulb into an outlet that the inverter is
powering. Press the INVERTER ENABLE button on the
Freedom SW. The INVERTER ENABLED LED turns on.
The inverter should run the load using battery power.
6. To test the charger, reconnect the AC input power to
allow AC to the AC input. The AC In/Charging LED
should start flashing after a brief delay. Any AC loads
previously powered by the inverter will also work at
this time.
•
NOTE: On dual input models, only AC Input L1
needs to be powered for the unit to operate.
Freedom SW AC and DC Side
Panels
If AC output or passthrough voltage issues exist, check
the circuit breakers located on the side panel and reset if
necessary.
The DC side of the Freedom SW has the equipment
ground plug, the positive (+) battery terminal, and the
negative (-) battery terminal plus the remote network com
port and battery temperature sensor com port.

the AC IN LED turns on.
You can run your appliances
from an AC source like the
utility grid or a generator.
Charging
Flashing
Green
Freedom SW is connected
to a qualified AC source,
is charging and passing
power to AC loads.
Your battery bank is being
replenished and AC loads
are receiving power.
Fault
Steady
Red
A fault condition
was detected on the
network.
Investigate and clear the
fault condition.
Warning

Red
A warning is detected.
Investigate by examining
warning logs on SCP.
1. Remote (REM) jack provides connection for the
Freedom Sine Wave remote panel.
2. Battery temperature sensor (BTS) jack provides
connection for the battery temperature sensor
(supplied).
7. Remove the AC input power. The inverter/charger
should transfer to invert mode immediately. (The
transfer relay will make a clicking sound and the
INVERTER ENABLED LED will turn on.) Loads should
continue to operate uninterrupted. If any part of this
test fails, determine the cause before using the unit.
8. Monitor the Freedom SW Front Panel. The indicator
LEDs on the front panel show you the operating
status of the Freedom SW. A description of the LEDs
is provided. If none of the front panel LEDs are on,
refer to the “Troubleshooting” section in Xantrex’s
Owner’s Manual.
