Introduction
This manual is intended to provide assistance to an installer for the
installation and commissioning of the range of Freedom Won LiTE Home and
Business HV lithium iron phosphate (LiFePO4) energy storage modules. This
document is not intended to provide
detailed information of the inner workings of Freedom Won LiTE that is not
relevant to a person that is performing the installation and final
commissioning. Supplementary information relating to programming of the built-
in battery management system for
specific applications is available to approved integrators directly from
Freedom Won.
This manual does not attempt to cover all the details pertaining to the setup
of third-party equipment in relation to the interface and necessary
functionality to work with the LiTE. Freedom Won however is available at the
contact details on page one to provide direct support where necessary for
supported third party brands.
Product Description
The Freedom Won LiTE technology is available in various standard sizes to meet
all residential, commercial, and industrial applications, ranging in models
from 5kWh up to 2500kWh.
Larger systems are provided by Freedom Won based on specific project
requirements by installing multiple units of the same model battery in
parallel.
Freedom Won offers the following ranges in the LiFePO4 technology:
- LiTE 12V
- LiTE Home and Business
- LiTE Home and Business HV
- LiTE Marine
- LiTE Mobility (golf carts, forklifts etc)
- LiTE Commercial (including LiTE Commercial HV and HV+)
- LiTE Industrial
This manual covers the standard voltage models of the LiTE Home and Business
HV range from 15kWh up to 80kWh. Please refer to the manuals specific to the
other ranges for assistance with other models.
The LiTE Home and Business HV models vary in voltage from 153V nominal up to
614V nominal. The Freedom Won LiTE HV range is designed for specific Higher
Voltage inverters. The acceptable voltage ranges for the various HV inverters
vary quite
substantially so it is important to check the inverter specifications and make
sure that you select the correct Freedom Won LiTE HV battery voltage. Contact
Freedom Won for assistance if there is any doubt. A list of supported HV
inverters is available in Section
5.3. The nominal voltage options are presented in Table 2.1. If none of these
options is suitable for your preferred inverter, please contact Freedom Won
for assistance with the right solution for your needs.
Table 2.1 provides an overview of the Freedom Won LiTE Home and Business HV
range.
There are six primary, as included in the table. The models are classified in
terms of energy capacity.
An image with numbered labels pertaining to the following paragraphs is
provided in Figure 2.1. The model number denotes with the first number [1] the
total energy storage capacity in kWh of each model. The second number [2]
denotes the average amount of
energy in kWh that should be withdrawn per cycle (on average) in order to
optimise the life of the lithium cells. This equates to 80% of the total for
each model i.e. 80% depth of discharge (DoD). Note that all Freedom Won LiTE
batteries offer a maximum of 90% DoD as standard.
The range is designed with a tall and slim profile with the “Home” models
intended to be wall mounted (floor mounting is also possible – all models are
supplied standard with plastic feet). The larger “Business” range is floor
standing with rubber feet for the 40/32 HV and aluminium feet with plastic
pads on the underside for the 60/48 HV and 80/64 HV.
The aluminium feet on the latter two models have a height of 100mm and allow
for shifting the battery once upright using a pallet trolley.
The Ah capacity is not provided in the table because this varies depending on
the voltage option, instead use the kWh capacity rating for sizing
information.
The maximum current for each model is governed by the rating of the built-in
circuit breaker [3], which has been sized below the maximum current capability
of the lithium cells to ensure their protection. There is no noticeable cell
temperature rise during operation and no active cooling of the cells is
required. The time limit for operation at the maximum current is 5 minutes in
a 10-minute cycle. To ensure that the circuit breaker does not trip in normal
operation it is advised that the design of the system aims to
remain at or below the continuous current value.
The maximum operating voltage of each battery model is 112% of the nominal
voltage and the minimum operating voltage is 88% of the nominal voltage.
The BMS will command the connected inverter with the CAN Bus interface to stop
discharging the battery at 10% SoC (90% DoD), which roughly equates to 88% of
the nominal voltage). Under high load the voltage may drop lower whilst still
above 10% SoC.
The battery breaker will eventually trip the battery at around 80% of the
nominal voltage to protect the cells from undervoltage.

The weight of each model is given in the tables. The Freedom Won LiTE Home
15/12HV and 20/16HV models can be manually lifted by four people and
maneuvered by two. The larger
units typically require lifting equipment of varying degrees for handling and
installation as explained later in this document.
The dimensions given are for the principle outlines of the aluminium housing
and exclude items that protrude such as the DC cable glands and the circuit
breaker handle.
The DC cables exit the unit through glands [4] located on the top right-hand
side of the casing. For this range all models have one positive and one
negative cable. The sizes and lengths are provided in Table 2.1. The correct
cable lugs for connecting these leads to the inverter must be in hand when
doing an installation. If there are several inverters and charge controllers
that need to be connected to the battery it is advisable to install a DC
connector box to use as a junction point from which to branch out to all the
battery
connected equipment.
Note the model specifications label and serial number on the label shown
by label [5].

Two RJ45 sockets [6] are provided, one for connecting the CAN interface from
the battery to the system controller or directly to the inverter depending on
the brand, and another for connecting the battery to another battery or for a
termination resistor (more
detail later in manual).
A USB Serial Connector [7 – concealed] is fitted to the upper left-hand side of
the housing for use by technicians for programming the required profile onto
the BMS or updating firmware. The required profile is typically loaded by
Freedom Won prior to delivery but installers are advised to keep a USB
“printer” cable handy during commissioning to allow
Freedom Won or the distributor to program batteries remotely on behalf of the
installer via the installer’s Windows laptop if necessary. A USB cable is
provided with each battery.
An error reset button [8 – concealed] is positioned adjacent to the DB9 plug.
Freedom Won LiTE is also fitted with a State of Charge (SoC) display [9], which
includes a red LED error indicator [10] and below it a “reduced power”
indicator.
Figure 2.2 USB “printer” Cable for Programming all Freedom LiTE models
produced after May 2020The ON button [11] and OFF button [12] are located
beside the SoC display.
All LiTEs have feet as standard, whether needed or not [15].
A hard point is supplied on the top for the 15/12 HV and 20/16 HV models [14]
for inserting an eye bolt that can be used for hoisting the battery onto the
wall mountings. The LiTE 30/24 HV and above are supplied with permanently
installed eye bolt(s).
DC Bus Design Notes
The LiTE range includes an integrated battery DC breaker/isolator that breaks
the positive cable continuity inside the battery. This breaker, on all Home
and Business models, is rated for a 36kA fault (short circuit) current. The
system therefore does not require another DC isolator or breaker except where
required in relation to conformance with the Clean Energy Council of Australia
battery design Best Practice Guide, which states that, should the internal
battery isolator not offer isolation of BOTH the positive and negative
terminals of the battery, an external isolator is required that can isolate
both the positive and negative cables/terminals of the battery.
The approximate short circuit current values of each battery model are
provided in the table below:
Table 3.1 Short Circuit Current for LiTE Home and Business Models
Freedom Won LiTE| Home
15/12 HV| Home
20/16 HV| Home
30/24 HV| Business
40/32 HV| Business
60/48 HV| Business
80/64 HV
---|---|---|---|---|---|---
Short Circuit Current [A]| 3100| 3600| 4700| 5100| 5800| 6200
The external isolating device required for installations in Australia should be designed to withstand these fault levels (short circuit currents).
Transport, Handling and Mounting
The Freedom Won LiTE units are packaged in protective layering and fastened
into a wooden crate with pallet type feet, which allow lifting with a forklift
or a pallet jack. The 15/12 HV and 20/16 HV models may be manually handled by
four people but are best
handled by a pallet jack or forklift if available. The 30/24 HV, 40/32 HV,
60/48 HV and 80/64 HV models must be handled with care by a forklift or pallet
jack of the required lifting capacity rating.
The “Home” series is designed for wall mounting in order to preserve room and
floor space and offer a convenient obstruction free and aesthetically pleasing
solution. Each model is fitted to the wall using two Rawl Bolts. The Rawl Bolts
are inserted into correct
diameter pre-drilled holes in the wall. The bolts must first be tightened
substantially so that the internals of the Rawl Bolt have gripped tightly into
the wall, and then the bolt must be turned out slightly with the head
protruding so that about 5mm of the bolt shank is visible. This pre-tightening
prevents the bolt from being pushed into the wall when mounting the LiTE. The
Freedom LiTE has two keyhole shaped holes on the back, which are shaped to fit
over the bolt heads and then a narrowed section secures around
the bolt shank as the unit is lowered into its final position. The 15/12 HV and
20/16 HV models are hung using M8 bolts whilst the 30/24 HV model is hung on
M10 bolts. The larger models are not equipped with keyholes and must be
mounted upright on the floor.
The centre to centre spacing of these bolts must be applicable to the model
being installed. It is critical that these bolts are mounted within 1mm of the
correct dimension and must be perfectly level.
Figure 4.1 Bolt Mounting Keyhole on Rear of LiTE Casing – floor mount retaining
tab andfitted eye bolt also visibleEye bolts fixed to the top of the battery can
be used for hoisting the unit up to the required height for fitting to the
wall. The eye bolt on the models up to the LiTE 20/16 HV can be removed after
installation. Ensure that you have one M12 x 1,75 thread eye bolt
rated for 450kg or more for the models that are not supplied with permanently
fixed eye bolts.
Lifting the batteries by the eye bolts should be performed using a mobile
gantry crane or a high lift pallet jack.
Figure 4.2 Eye bolt Example Figure 4.3 Eye bolt Installation on a LiTE 15/12HV model (remove after installation) The units can alternatively be lifted to the right height and onto the hanging bolts using a high-lift pallet jack such as shown in Figure 4.4. A site assembled gantry with electric winch is shown in Figure 4.5. This gantry is available from Freedom Won as an accessory and is available with various gantry widths and lifting capacities.

Fig 4.5 Site Assembled Gantry with Electric Hoist Caution:
- Great care must be taken to ensure that the Rawl Bolt has properly located into the narrowed section of the mounting hole before removing the support.
- Handle the Freedom Won LiTE with great care when lifting and manoeuvring. It should remain either lying flat on its back, on a long side, or vertically upright (it should not be placed upside down or on its front face. When manoeuvring through a doorway on its long side be certain to pack spacing foam to prevent damage to the plugs and glands.
- Do not allow the pallet jack to over centre if it is a model with forks longer than the lower arms
- Take care not to knock any of the protruding items against obstacles during handling such as the DC cabling and plugs and the circuit breaker handle.
- Take care not to scratch the LiTE during handling. Packaging foam should be used to protect the paint when being handled on a trolley or pallet jack.
- Always ensure that lifting equipment and slings are adequately rated for the lifting weight.
- Ensure that the eye bolts are fully screwed into the hard point thread on the top of the unit before lifting.
- Wear personal protective equipment such as safety shoes and gloves while handling and mounting the Freedom Won LiTE
- Always ensure that you have enough people on hand to perform the operation safely, i.e. at least one person to guide and stabilise and one person to hoist or handle the pallet jack or gantry.
- The gantry can be configured for wall mounting – when using the gantry in this configuration absolute care must be taken to prevent the gantry from being pulled over by non-vertical tension on the rope.
Mounting and Environmental Requirements
The LiTE Home and Business HV models are designed strictly for indoor use away
from moisture and direct sunlight.
No specific venting is required since the LiTE emits no hazardous gases,
however air circulation may be required to ensure room temperature is
maintained at reasonable levels, preferably below 30˚C (see LiTE warranty for
information upper temperature limits for hot environments).
Room heating may be required in cold climates to keep the room above 0˚C,
since charging of the LiTE is not permitted below 0˚C. Ambient environments
that regularly exceeding 40˚C should employ room cooling if practicable to
ensure optimal LiTE service
life.
Temporary storage or transport of the battery is permitted in the range -20˚C
to 45˚C, however extended storage should be between 0˚C and 30˚C.
The LiTE may be mounted directly against a wall or on the floor. There is no
minimum requirement for spacing around the battery from other objects provided
that these objects do not generate heat and that the vents on the sides of the
battery are not blocked. Note however that access is required to the USB
programming port on the left side, and the CAN Bus plug sockets and cable
exits on the right side.
The LiTE should be installed at least 500mm way from a heat source.
The LiTE Home and Business IP rating is IP20.
Connecting the Freedom LiTE
5.1 Power Cables
The Freedom Won LiTE is simple to connect to the battery inverter. First of
all you will connect the battery positive and negative cables to the inverter
terminals using the applicable lugs.
Caution: Prior to connecting the positive and negative cables to the inverter
be sure to check that the main battery circuit breaker is switched off. This
will ensure that there are no short circuits between the loose ends of the
cables and that you do not shock
yourself!
The cables are supplied with the Freedom Won LiTE, permanently fixed into the
unit and secured onto the casing using compression cable glands. Attach crimp
lugs to the ends of both cables ensuring that the correct terminal size is
used, and the lug is matched to the size of the cable. The positive cable is
red, and the negative cable is black. This is confirmed by + and –signs on the
battery casing beside the respective cables. See Tables 2.1 for the cable size
and quantity fitted to each Freedom Won LiTE HV model. The cable cross
sectional area is based on an acceptable voltage drop with the inverter being
mounted on the wall adjacent to the Freedom Won LiTE battery so that the cable
run is less than 5m (note however that the standard cable length is 1,8m,
longer cables available on request).
Cable runs longer than 5m should be assessed and larger cables considered for
extending the Freedom Won LiTE cables to minimise voltage drop. Double
Insulation welding cable is recommended, rated for at least 600V.
The cables may be routed through trunking and connected into the inverter on
the positive and negative terminals, respectively. On Installations where
there is more than one inverter a DC connector box is required as a common
point to route the DC cables to
each inverter so that the DC cable run can be kept the same length to all
inverters.
5.2 Control Cables – Overview
For controlling external devices, you will need to connect the CAN Bus cable
that allows the Battery Management System inside the Freedom LiTE to control,
and interface with, these devices.
The CAN Bus connection is made using the RJ45 plug with the pin configuration
on the battery plug end provided in Table 5.1.
Table 5.1 Colour Coding and Pin Configuration for CAN Bus UTP Control Cable
RJ45 Pin No. | Standard Ethernet Cable Colours | Wire Function |
---|---|---|
7 niP | Brown/White | CAN HIGH |
8 niP | Brown | CAN LOW |
Only Victron is accommodated by the pin populations in Table 5.1 using a
standard Type T-568B RJ45 terminated UTP cable. For other inverter brands,
please refer to the respective inverter brands’ manuals for their pin
configuration or contact Freedom Won
for assistance. Some brands are covered in Table 5.2 below.
Special CAN cables for supported inverter brands are available from Freedom
Won (see accessories section). Please ensure that you use a correctly
configured cable to prevent damage to any CAN Bus devices.
5.3 CAN Bus Control – Detailed Description
CAN is a widely used communication protocol in systems with many devices that
must report their status or send commands to other devices on the same
network. The Freedom Won LiTE BMS can transmit messages and commands in CAN
protocol to provide information to, but more importantly to control, external
devices. CAN allows great versatility and provides a simple installation
because there are only two wires required in this form of communication,
namely CAN High and CAN Low. In order for an inverter or charge controller to
be controlled by CAN it must first of all be equipped with a CAN interface as
well as a suitable method of connecting the CAN wires. Further to this the
Freedom Won LiTE BMS must be programmed with a CAN messaging profile that is
developed for the inverter or charge controller being used. This profile must
be specifically developed for each inverter model or model range. To date
Freedom Won has developed CAN profiles for the following high DC voltage
inverter equipment in relation to the Home and
Business HV range:
- Ingeteam Sun Storage Battery Inverters
- ATESS (HPS and PCS ranges)
- Solax
- Goodwe
- Socomec
- Sofar Solar
- Solis
- Elpower
- Vensys
- ABB
Freedom Won welcomes any requests to produce and test BMS CAN profiles for
other inverters that are CAN equipped for BMS interfacing. For a list of
approved CAN interfaces for 48V inverters please refer to the Home and
Business 52V manual.
The CAN interface can provide the following functionality to compatible
devices:
i. Charge Current Limit of all LiTEs connected
ii. Discharge Current Limit of all LiTEs connected
iii. Actual State of Charge (minimum of all lights connected)
iv. Actual Battery Temperature (highest of all lights connected)
v. Actual Voltage
vi. Actual Current (total of all LiTEs connected)
vii. Maximum real time charge voltage setpoint
viii. Battery Name
ix. Highest Cell Voltage of all LiTEs connected
x. Lowest Cell Voltage of all LiTEs connected.
xi. Firmware Version
xii. Ah capacity of all batteries connected
xiii. Advanced communication between all connected LiTEs
The CAN 2.0 Part A and Part B standard uses the SAE J1939 standard in the
LiTE. It is necessary to install a 120 Ohm resistor on each extreme end of the
CAN cable (splices do not require a resistor). Most devices operating on CAN
have two plugs to connect an
incoming cable in and then outgoing cable on the CAN Bus. The first and the
last device in the chain must have a termination resistor plugged into the
spare (second) plug. These resistor plugs are available from Freedom Won (if
you are using Victron then you can use the Victron supplied resistors). SMA,
Imeon, Solax and Victron operate on this basis for example. Ingeteam has a
separate CAN terminal block for bare wires to be inserted from the BMS and
these units have an internal resistor fitted into the device. All Freedom Won
LiTE models have two CAN plugs for parallel configurations (Figure 4.2) and to
allow fitment of the termination resistors on the end of line units. Where one
LiTE is installed or where it is the end of line CAN device, the LiTE must be
fitted with a termination resistor.
The LiTE is supplied with a termination resistor as standard. The other
devices must be fitted with the correct termination resistor for that
particular brand, where applicable (some devices have a built-in resistor).
Note that the resistor supplied by Freedom Won
must only be used on the battery.
The third-party device manuals must be referenced for all details regarding
connecting the CAN interface.
The LiTE profile is in most cases specifically designed for a particular
inverter from the above list. The inverter pairing should be stated when
ordering a HV battery so that the battery can be shipped with the correct
profile. If this is not done the profile can easily be changed during
commissioning by your distributor for Freedom Won technical support.
Fig 4.1 provides the standard colour coding for an Ethernet cable (note that
there are other variations so double check this).

If your inverter is not included in this table or you require more information
on how to connect the CAN Bus on your inverter, please contact Freedom Won for
assistance.
5.4 Parallel Configurations
It is permissible to connect multiple Freedom Won LiTE’s in parallel provided
that the Freedom Won LiTE model size used is the same throughout. It is
however more cost effective to purchase one larger Freedom Won LiTE model than
connecting multiple
units in parallel. This type of installation should be reserved for future
expansion where it is not feasible to purchase a model large enough upfront
for future requirements (financial constraints).
The LiTE operating system will automatically configure which battery is the
master and which ones are slaves (the first battery to be switched on in a
parallel setup will be the master). The LiTE is therefore plug and play
capable, there is no configuration required
during commissioning.
The Master LiTE must be connected to the slave LiTE’s via the CAN Bus using
standard LAN cable.
Where CAN Bus is used to control the inverter(s) and charge controller(s), the
CAN Bus from any battery can be connected to the inverter directly or the
system controller, depending on the product brand.
Figure 4.2 Picture showing 2 x RJ45 Sockets for CAN Bus, the DC cables,
High Voltage warning label, model specifications label Figure 4.2 CAN Bus
Connection Example with Three LiTE HV’s – the inverter includes the CAN Bus
connection; in some brands the CAN may connect to a separate
controller. In Fig 4.2 the inverter may include a built-in
resistor with a dip switch to enable it or it may provide a second plug to
accept a RJ45 termination resistor. Some inverters have screw terminals to
accept a bare wire instead of a plug.
Freedom Won LiTE batteries can configure themselves automatically for master
and slave configurations with up to 20 slaves. No programming is required,
simply connect the CAN Bus cables and switch on the LiTE’s. The Master will be
the first battery that was
switched on.
If the master LiTE trips, one of the slaves will take over as the master
automatically without any interruption of service.
Freedom Won offers a fair trade in on Freedom Won LiTE’s on the purchase of
new units, which is an option for somebody wishing to expand their battery
capacity instead of installing parallel units. Please request more detail from
Freedom Won if this is your
upgrade preference.
New units can be placed in parallel with old units up to about 5 years or 1
500 cycles, after which it is preferable to trade in for a new larger unit.
Programming the Freedom LiTE
The USB plug on the left-hand side of the Freedom Won LiTE is used for setting
up the profile of the BMS. The computer must have the correct utility software
installed.
Programming of the BMS is intended only as a function to be performed by
Freedom Won and approved installers. The manual on how to operate the BMS
along with the utility is available to approved installers from Freedom Won.
Write access to the BMS profile is password protected, however users and owners
may request read only access.
Switching on the LiTE
The LiTE is fitted with an “ON” button. Press this button for at least 5
seconds to switch on the BMS inside the battery. Once the BMS has been
energised you will observe the SoC display come to life with the SoC level
shown. Confirm at this stage that the error light is not illuminated. If it is,
contact Freedom Won. If the Reduced Power light is illuminated, do not be
concerned, it should extinguish after the battery has been in operation for a
few hours.
Once the BMS has been energised, the main breaker may be switched on by
pushing the breaker upwards. Ensure beforehand that you have secured the DC
cables to their proper locations and that the rest of the system is ready to
receive battery voltage.
CAUTION: The batteries in this range operate at potentially lethal voltages,
the installer must make certain that there is no risk of electric shock before
switching on the battery!
Note: On some inverters there is a large inrush current when switching on the
DC supply. It is important in these instances to pre charge the DC bus. Other
inverters are equipped with a pre-charge circuit – check before you switch on
the battery to avoid damaging the battery breaker.
To switch off the DC output from the LiTE, pull down the breaker. To switch
off the power to the BMS, press the “OFF” button situated to the right of the
“ON” button. This will also trip the breaker if it is still on at the time.
The LiTE must be switched off fully when not in use to prevent self-discharge.

Settings Required for Setting up Inverters and Charge Controllers
The maximum and continuous discharge and charge currents for the respective
models are provided in Table 2.1. The inverter should be configured within
these limits. Generally the CAN bus messages from the battery will determine
these limits.
The voltage settings on the inverter must align with the highest and lowest
values discussed in Section 2. In some cases, the inverter menu requires the
cell level voltage values. Please contact Freedom Won for assistance when
configuring these inverters.

Warranty and Repair
The Freedom Won LiTE is sealed with a tamper proof warranty seal. It may not
be opened by anyone other than Freedom Won and installers or repairers that
have been explicitly approved by Freedom Won. The warranty on the unit will be
void if the seal is damaged or missing.
If the Freedom Won LiTE indicates an internal problem, please contact Freedom
Won or the installer that installed the system. Freedom Won will arrange that
it is inspected and repaired.
The warranty will not cover damage to the control wiring resulting from draw
of excessive current or any damage resulting from lightning. Damage caused by
physical means to the battery housing, external and internal fittings, such as
impact with other objects, or being dropped, is not covered by the warranty.
The standard warranty period is 10 years or 4 000 cycles at an average of 80%
DoD, whichever should first occur. The battery is required to provide at least
70% of its new capacity at the end of this period or cycle count. The BMS
records the number of cycles used. If you suspect that your Freedom Won LiTE
is delivering substantially below its minimum performance, please contact
Freedom Won for an investigation. If the unit is found to be underperforming
it will be serviced such that the minimum performance guarantee is again
restored. Freedom Won may arrange for an on-site service or for collection of
the unit for servicing at our facility. This will be mostly determined by the
geographic location, ease of access to or removal of the unit, and size of the
unit.
For more detailed warranty information please contact Freedom Won.
Note: the above warranty statements apply to Lites sold by Freedom Won on
or after 1 September 2019 only. For LiTEs sold by Freedom Won prior please
contact Freedom Won for the correct documentation.
Expected Product Life
Freedom Won LiTE is designed for optimal life cycle cost, which is a fraction
of any other battery technology available on the market, in particular from
25% to 35% of the lifecycle cost of the range of lead acid and associated
variants on the market. Please contact
Freedom Won if you would like more detailed information for comparison with
lead acid batteries than what is available on our web site.
Freedom Won LiTE is expected to operate for about 16 years in a daily cycling
scenario for more than 5 500 cycles with an average of 80% DoD. For occasional
cycling applications (for typical load shedding for instance, as is
experienced in some countries) the service life expected is 20 years or more.
For applications where the cost per kWh delivered by the battery during its
lifetime is of prime importance (i.e. maximum return on investment) we
recommend that the battery be sized for an average cycle discharge of 50-60%
DoD. In a daily cycling scenario such as for optimal solar self-consumption
and off grid systems the expected service life is then 20 years or more than
7500 cycles. The defined end of life in this instance occurs when the battery
capacity falls to 60% of the new capacity.
Troubleshooting Guide
Most issues with the Freedom LiTE can be resolved using the guide below. If a
problem
cannot be resolved after referencing this table please contact Freedom Won or
your
approved Freedom Won supplier.
Table 12.1 Troubleshooting Guide (applicable to units with On and OFF
buttons)
No | Problem Description | Cause/Solution |
---|---|---|
1 | Eye bolts do not screw into hard point on top of Freedom Won LiTE | Check |
that you have the correct eye bolt with the correct thread pitch – M12 x 1,75
2| The rawl bolt head does not fit into the hole on the back of Freedom Won
LiTE (wall mounted models)| Freedom Won LiTE (wall Check that you are using
the correct size Rawl Bolt as specified in this manual and that you have after
positively tightening the internal gripping collar turned the bolt out again
so that there is about 5mm of the bolt shank exposed so that the back plate
can fit easily behind the bolt head. If the wall is uneven it may be necessary
to turn the bolt head out a little more. Do not turn it so far out that there
is less than the full thread length engaging on the internal locking collar.
3| The Freedom Won LiTE has no voltage on the main output cables| voltage on
the main output Check that you have switched on the main breaker switch. Note
– only turn this on once you are satisfied that you have completed the
installation and that there are no DC or control wires that can short out or
touch
ground or other wires. Also ensure that you are ready to accept AC voltage
onto the inverter output before switching this breaker on. Also confirm that
you have energised the BMS first by pressing the “ON” button for 3 seconds and
as evidenced by the lights on the SoC display. If voltage is still not present
with the breaker switched on it is possible the breaker has been damaged –
please contact Freedom Won
4| The BMS (indicated by battery SoC display lighting up) does not stay on
after the ON button is pressed and released| 1. Error on the BMS. Check
whether the red error light is illuminated on the SOC display when the ON
button is held in. You can try to reset the error by pressing the RESET button
for about 2 seconds and release. This should clear the error and allow the BMS
to stay on after releasing the ON button.
2. Battery has been discharged to critically low level – remove all potential
loads from the battery and switch off the inverter(s). Then try to switch on
the BMS.
3. Battery has been charged to critically high voltage level – usually
leaving the battery for an hour will allow the cell levels to drop down within
acceptable levels and allow the BMS to be switched on again.
4. If the BMS still does not switch on, please contact Freedom Won or
Authorised Distributor
5. Releasing the ON Button to soon – hold the ON Button in for at least 5
seconds before releasing.
5| The main breaker switch keeps tripping each time I attempt to switch it on|
There are several potential causes:
1. The Battery Management System has not been switched on. The ON button must
be pressed for 5 seconds. On release the SoC Display must remain illuminated.
2. High inrush current on certain inverters – First preference is to pre
charge the DC bus by switching on the solar charge controllers if present and
in daytime. If this is not possible switch on the AC feed into the inverter
and switch on the
inverter. Some makes will then pre charge the DC bus. You can also use a
precharge resistor for this. If this does not work after the second attempt
investigate the other options.
3. Short circuit on the DC Bus or faulty inverter or MPPT causing high
currents
4. In a system with multiple LiTEs in parallel the reason could be that the
battery you are trying to switch on is at a different voltage to the others –
the voltages must be similar (within 1V of each other) on all batteries when
switching them onto a
common DC bus. If none of the above solve the problem, you will need to
contact Freedom Won or your authorised installer for assistance with this
issue. It will be necessary to establish the reason for the error before
continuing with normal operation of the system. Repeated tripping is damaging
for the breaker.
6| After resetting the BMS the main breaker still will not stay up.| This is
most likely because the battery is fully discharged and the BMS is protecting
the cells from further discharge. Ensure that there is no chance of load being
applied to the battery by isolating the AC output from the inverter. Ensure
that the AC input to the inverter is live so that the charger may begin
charging the battery after you switch it on. Alternatively, an MPPT can be
used for this immediate charge if there is sunshine at the time. This charge
should increase the battery voltage to prevent further tripping. This problem
should not occur if the inverter control is working properly. If this does not
work, it is because the battery has been discharged too deeply and will need
to be reset remotely by Freedom Won by accessing your Windows PC connected to
the battery. The PC must have TeamViewer installed and you will need the RS232
adapter to connect the PC to the battery. Please contact Freedom Won.
7| I have switched off the main battery breaker switch to prevent discharge of
the battery but the SOC display lights are still on.| The BMS and SoC display
receive power directly from the battery and therefore the “OFF” Button must be
pressed to switch off the internal electronics.
8| The inverter will not come on even though the inverter switch is
selected to ‘on’.| The enable command may not be coming from the BMS or may
not be properly connected to the inverter or the inverter may not be properly
configured to deal with the enable command. If you are running on a CAN Bus
control with a compatible inverter and you are not observing the correct
enable response from the inverter check that the CAN High and CAN Low wires
are connected properly (ensure that you have the High and Low the right way
around and that you have connected the two end of line 120 Ohm resistor in the
applicable places. If this is not the problem then you need to confirm that you
have the right CAN profile programmed onto the BMS for the inverter in use
(baud rate or CAN messages may be for another inverter brand) or that you have
configured the inverter or system controller correctly. Check that your CAN
Cable is properly made up on the pin configuration and that the terminations
are good. Contact Freedom Won or your Authorised Distributor for assistance
9| The charger will not come on even though there is power on the AC
input of the inverter and the charger is activated in the inverter settings|
The battery might be full. Try discharging the battery for a while and observe
if the charger then comes on. If not then the fault finding process is similar
to above.
10| The Freedom Won LiTE error light keeps illuminating after each reset| If
the battery voltage is within limits this should not ordinarily occur. Contact
Freedom Won or an approved installer for assistance with determining the
problem. If the main breaker does not trip it is not a critical error and you
may continue using the battery while you make contact for assistance.
11| The pack voltage is within limits, but the main breaker still trips
seemingly at random| This could be caused by many things but is most likely
because the current draw is exceeding the battery current limit setting.
Measure the current with a tong tester while drawing your maximum typical load
to determine if you are exceeding the rated current for the respective Freedom
LiTE model. If it is not the current causing the trip it could be a weak cell
or extreme temperature of the surroundings. Both are unlikely. If the problem
persists, contact Freedom Won.
