Introduction

The Freedom e-GEN System solution from Xantrex is a lithium-ion battery-based power system that offers safe, clean, and efficient onboard power. The system features a Xantrex lithium battery pack and a choice between two Xantrex inverter/chargers, capable of delivering grid-quality AC power to run onboard appliances for an extended period of time. The ability to charge from both the auxiliary alternator and shore power offers flexibility and fast recharge, further empowering your road experience.

The Freedom e-GEN System consists of the following core components:

• Freedom SW 3012 Inverter/Charger or Freedom XC PRO Inverter/Charger
• Conext ComBox for Freedom SW and Tablet*
• Freedom X Remote Panel (Bluetooth)**
• Xantrex lithium battery pack and Xantrex BMS (Battery Management System)
• Auxiliary Alternator and dedicated regulator

This user guide provides you basic instructions on how to operate and maintain the Freedom e-GEN System. For more information, refer to each device’s Owner’s Guide.

• Applicable only when choosing Freedom SW 3012 Inverter/Charger. Some systems may come with a System Control Panel (SCP).
  ** Applicable only when choosing Freedom XC PRO Inverter/Charger.

Turn On Battery and Inverter

Turning ON the BMS

• A single, brief press of the POWER/RESET push button on the remote panel will turn on the BMS and engage battery power.

Turning OFF the BMS

• Press and hold the POWER/RESET push button for 3 seconds to turn off the BMS and disengage battery power.

Once battery power is engaged, you can enable and disable the inverter AC output through the SCP, the Conext ComBox app, or the FXC Control app** depending on which Xantrex inverter/charger you are using. Instant system status and aggregate usage data are available to help you monitor and assess your energy consumption.

• applicable to the Freedom SW only and the app requires an Android tablet.
  ** applicable to Freedom XC PRO only and an iOS/Android smart device with Bluetooth. XC PRO unit must be on.

RISK OF EQUIPMENT OR BATTERY DAMAGE

• Do not change the factory settings of the Xantrex inverter/chargers.
• Do not leave appliances on if they are not in use as this will drain the battery..

Failure to follow these instructions can result in damage to equipment and may void the warranty.

Monitor Xantrex Battery Status

The SoC LCD Display (PN: 881-0401-12) on the system remote panel powers up whenever BMS is turned on. Its screen has two lines
where battery information is displayed.

Press the Left (or Right) button to cycle through the following battery information displayed on the first (or second) line.

Low Battery Alarm (Orange Light)

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 immediately 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 Xantrex inverter/charger 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.

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 follow these instructions can result in damage to the battery and may void the warranty.

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.

RISK OF EQUIPMENT DAMAGE
Do not disconnect battery while the system is charging.
Failure to follow these instructions can result in damage to the battery and may void the warranty.

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 the recommended voltage.

Failure to follow these instructions can result in damage to the battery and may void the warranty.

Low Battery Recovery

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.

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.

Troubleshooting

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 lithium battery pack 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 and in consultation with a qualified technician.
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 Settings are from 1 Ah to 3000 Ah. 0 – 50 Ah are in 1 Ah increments. 50
Battery packAmp – 3000 Ah are in 10 Ah increments.
Hour capacity

Full Vlt
Full Voltage

Set this to the maximum per-cell voltage your battery reaches at the endof- charge. This will be used to synchronize the SoC LCD Display’s
100% reading when the battery reaches this voltage level.

Typically, this value is 3.55 V per cell. So, a 12 V (4 cell) battery is 4 x 3.55 = 14.2 V. When the battery reaches this voltage at the end of a
charge cycle, the SoC value will reset to 100%.

NOTE : If you notice that your SoC LCD Display’s value never reaches 100%at the end of a charge cycle, you may need to slightly lower the FullVlt value to what the voltage reading is on the LCD Display at the moment, when the charger turns off. This value must be higher than the resting voltage of the battery since the charger’s end voltage is higher than its resting voltage. The typical value range should be
between 14.0 and 14.4 V.

Min SoC
Minimal State-of Charge

This percentage value sets the Empty Battery level, also known as Reserve Capacity, so the user can utilize the BAT Gauge reading and not completely deplete the battery thus, preserving its lifecycles. For example, if this value is set to 10%, then the BAT Gauge will report 0% when there is still 10% reserve SoC. If you desire to use your battery to its full capacity and/or want the BAT Gauge to reflect true SoC, then set this value to zero.

In addition, when RVC Mode is enabled, the BMS will turn off battery power when SoC reaches this preset level (assuming it comes before battery voltage reaches RVC level), typically 3.00VPC. This allows the Xantrex Reserve feature to act on both voltage trigger and SoC level trigger, whichever comes first.

AGSR Lvl
Automatic Generator Start/Restart level

This percentage value determines the minimal Bat Gauge level at which the AGS/R circuit is triggered. AGS/R circuit triggers on voltage set to 3.05 V per cell, or the Low Bat level, whichever comes first, hence allowing flexible control of the generator starting point.

Temp Unit
Temperature Units

Set this to Fahrenheit (°F) or Celsius (°C).

Charge Eff
Charging Efficiency

This percentage value slows down the rate of SoC climb during the charge to compensate for battery losses during the discharge cycle. The
recommended setting is 98%. In applications with high discharge rates, energy losses are more pronounced, so this value must be set lower to accurately report SoC and BAT Gauge values during partial charges.This setting must be tuned experimentally for best accuracy. Ideal setting will cause SoC to reach 100% at approximately the same time as the charger is finishing up the full charge.

Dead Zone

Due to thermal drift in Hall Effect sensors when temperature fluctuations are wide and fast, the BMS might report non-zero current reading when no current is present. The Dead Zone value allows ignoring small current readings when they are likely false (such as, when small reading fluctuates between zero and non-zero values). Default value of 0.3A is recommended for best zero-point stability.

Idle Load
Shown as mA

This setting represents the constant idle load current powering the BMS system. This can be measured with a digital multi-meter in DC
amperage mode in series with the BMS’s negative reference wire. Allowed range is 0 – 200 mA. Since the idle current is usually too low to
register by internal hall-effect sensor but still affects SoC reading over long time periods when the battery sits idle, setting this value allows for a better long-term accuracy of the SoC counter.

Alarm
Alarm function

Turns ON or OFF an Alarm function, which drives the internal buzzer as well as the AUXOUT2 external relay circuit when the BMS is in Alarm state.

RVC
Reserve voltage cut off function

Default setting STD (Standard) would turn off the battery while leaving reserve charge, which can be accessed by pressing the Reset button. When set to EXT (Extended), the amount of reserve charge is increased on voltage-based triggers.

BMS LED Indicator

The e-GEN Xantrex BMS has an LED indicator integrated into the Power button on the unit itself. In some cases, there are also optional remote LED indicators – one to indicate power (On/Off/Alarm) status and one to indicate low battery status. Please refer to your specific
installation to check which LEDs, if any, you have available in your system.

Power On/Off/Alarm – This LED indicator is integrated into the Power button on the BMS unit or is installed remotely as an option.

• The LED is off when the BMS is turned off and battery power is disabled.
• The LED is on when the BMS is on and battery power is enabled.
• The LED flashes rapidly when BMS is in alarm state and battery power is disabled.
