Troubleshooting
PROBLEM
CAUSE
SOLUTION
Battery and LCD
Display are turned
off
Battery is low (reserve
shutdown).
Follow the steps in
and charge the
battery immediately.
Battery is critically low
(low voltage shutdown).
Follow the steps in
and charge the
battery immediately.
The system is turned off.
Press the POWER/RESET button to turn the system on.
BMS will not turn
on.
Battery temperature is
outside normal range.
Apply proper ventilation and make sure ambient
temperature is not too hot or too cold.
Battery is critically low.
Follow the steps in
and charge the
battery immediately.
Battery fuse is blown due
to overcurrent or short-
circuit.
Call for service. Do not replace fuses in the system by
yourself.
Battery
information on
LCD Display is
inaccurate.
Battery is consistently left
in a partially discharged
state causing SoC
reading to gradually drift.
Perform a full charge cycle to bring battery the SoC to
100% and the voltage to at least 14.2V to allow readings to
recalibrate. Perform weekly to maintain accuracy. Check
that the battery capacity is set correctly.
Charging from the
auxiliary alternator
is slow.
Alternator temperature
is too high.
Allow the alternator to cool down by providing sufficient
ventilation. When idle-charging, park the vehicle in a cool
spot.
No charging from
the auxiliary
alternator
Fuse blown or the
alternator or regulator is
damaged
Call for service
NOTE
: Refer to the Troubleshooting chapter in the Freedom SW Owner's Guide for troubleshooting tips for your inverter/charger. Contact
customer service if a problem persists.

System and Battery Maintenance
1. Have a qualified service person first check the wiring and connections for wear
and tear during routine vehicle (RV) maintenance.
2. Then, check the second alternator and belt for wear and tear and appropriate belt
tension. Refer to this guide and all applicable guides for safety warning
information.
If the Freedom e-GEN System is in regular use, then it is recommended that the
Xantrex Battery be fully charged a minimum of once per two weeks in order for the
Xantrex BMS to recalibrate its State of Charge (SoC) setting. This process also
ensures that the SoC meter maintains its accuracy.

BMS Configuration
Xantrex ships every BMS unit pre-configured for the specific lithium-ion battery. However,
in some cases a customer may need to make changes to those parameters suited to their
system requirements.
The BMS configuration can be done using the two buttons on the SoC LCD Display (sold
separately).
Configuring BMS using the SoC LCD Display
Unit
To enter the BMS Configuration Menu:
1. Long press for six seconds both buttons on the LCD Display. The BMS will enter
Setup mode and will display the first configuration parameter and its current value.
2. Press the left button to scroll through the range of values.
3. Press the right button to lock the value and move to the next parameter screen.
NOTE
: If no buttons are pressed within five minutes, the LCD will exit Setup Mode and
switch to Display mode automatically.
The following list describes the setup screens and their variable descriptions.
Pack Size
Battery pack Amp
Hour capacity
Settings are from 1 Ah to 3000 Ah. 0 – 50 Ah are in 1 Ah increments. 50
– 3000 Ah are in 10 Ah increments.

Low Battery Alarm (Orange Light)
0 A
REMOTE
PANEL
The orange light on the system remote panel is
illuminated when battery voltage is low (12% battery
capacity left). When this occurs, remove load and
charge the battery either by turning on the vehicle
engine or connecting to shore power.
If you ignore the orange light and continue to drain the
battery, the Freedom SW will stop inverter operation
and cut power to your AC appliances. The BMS also
monitors battery capacity and will trigger shutdown
events to protect the battery.
At 10% battery capacity, a reserve shutdown event occurs. A single press on the
POWER/RESET button will re-engage the battery and allow access to the reserved
capacity. Follow the steps in the “System Charging” section to begin charging the battery.
At 3% battery capacity, the battery is depleted and a low voltage shutdown event occurs.
Follow the steps in the “Low Battery Recovery” section and charge the battery
immediately.
NOTICE
RISK OF BATTERY DAMAGE
Do not allow the battery to be depleted. Charge the battery immediately when the low battery alarm
orange light illuminates.
Failure to followthese instructions can result in damage to the battery and may void the warranty.
6
System Charging
When the battery’s SoC is greater than 10% and while battery power is still engaged, you
may charge the battery by engaging power from the charging source.
When SoC is less than 10% but greater than 3%, and the reserve shutdown event has
occurred, press the Power button on the BMS. While battery power is engaged, start
charging the battery from the charging source.
NOTE
: When charging, avoid using heavy loads to prevent prolonged charging time. Also,
avoid using heavy DC loads during charging to prevent the system from transitioning to
thermal protection mode.
To stop charging, disengage the power from any and all charging sources. Do not turn off
the BMS to disconnect the battery while the system is charging.
NOTICE
RISK OF EQUIPMENT DAMAGE
Do not disconnect battery while the system is charging.
Failure to followthese instructions can result in damage to equipment and may void the warranty.
NOTICE
RISK OF BATTERY DAMAGE
• Fully charge the battery and turn off the BMS when the system is not in use for less than a month.
Observe proper storage instructions from the battery manufacturer for long-term storage.
• Do not charge the battery in ambient temperature below freezing.
• Do not charge the battery above 14.8V.
Failure to followthese instructions can result in damage to the battery and may void the warranty.
7
Low Battery Recovery
NOTICE
RISK OF BATTERY DAMAGE
Turn off (or disconnect) all loads completely before performing a Low Battery Recovery procedure.
Failure to follow these instructions can result in damage to battery.
When SoC is less than 3% and the low voltage shutdown event has occured, charge the
battery immediately through an approved charging source. Follow the steps below.
1. Turn off (or disconnect) all DC and AC loads completely.
2. Start charging.
NOTE
: If charging does not commence, then it is possible that the battery has been
completely depleted. The battery including the entire power system has to be serviced by a
qualified person such as an authorized technician. Contact your dealer for service.
NOTICE
RISK OF BATTERY DAMAGE
Do not perform the low battery recovery procedure repeatedly. Contact customer service so they can refer
you to an authorized technician for service.
Failure to follow these instructions can result in damage to battery.
