1. Introduction
This manual is intended to aid an installer with the installation and commissioning of the
range of Freedom Lite lithium iron phosphate (LiFePO4) energy storage modules. This
document is not intended to provide detailed information of the inner workings of Freedom
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 inverter brands.
2. Product Description
The Freedom 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:
1. Lite 12V
2. Lite Home and Business
3. Lite HV Home and Business
4. Lite Marine
5. Lite Mobility (golf carts, forklifts etc)
6. Lite Commercial (including Lite Commercial HV and HV+)
7. Lite Industrial
This manual covers the standard voltage models of the Lite Home and Business range from
5kWh up to 80kWh. Please refer to the manuals specific to the other ranges.
The standard Lite voltage is 52V nominal (to suit 48V systems). The Freedom Lite HV range is
designed for specific Higher Voltage inverters such as those from Ingeteam (Ingecon 1Play
3TL and 6TL). The Lite Commercial range varies from 52V to 800V depending on customer
requirements (including the HV and HV+ models). The Industrial range varies from
approximately 500V to 800V depending on customer requirements.
The Lite Marine range of lithium batteries is available on request with similar specifications
to the Home range including 13V and 26V options to suit 12V and 24V systems respectively.
These models are water resistant (IP65) and designed for mounting on the floor or
horizontal deck and have dimensions that are different to the Lite Home models. For more
information on these models please contact Freedom Won.

Table 2.1 provides an overview of the 52V Freedom Lite Home and Business range. There
are eight Freedom Lite models in the Home and Business range, as included in the table,
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 Lite batteries offer a maximum of 90% DoD as standard.
The range is very compact with the “Home” models up to the Lite Home 20/16 intended to
be wall mounted (floor mounting is also possible – all models are supplied standard with
plastic feet). The larger “Business” range is designed for floor standing with aluminium feet
with plastic pads on the underside.
The Ah capacity is also provided in the tables for each model for easy reference.
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. 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 30 seconds in a 40 second
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.
For the 52V models the absolute maximum allowable voltage when fully charged is 56V,
however a more typical inverter charge setting range is 55.5V to 55.8V, depending on the
inverter voltage tracking accuracy. The voltage normally used as the minimum cut off is 48V,
however this will not typically be reached when operating down to 90% Depth of Discharge
(DoD). The BMS will command the connected inverter with CAN Bus interface to stop
discharging the battery at 10% SoC (90% DoD), which roughly equates to 49,0V). Under high
load the voltage may drop to 48V whilst still above 10% SoC. A voltage of 48V or even lower
can be observed in systems without a CAN Bus interface or where the standby current draw
on the inverter has caused the battery to be discharged below 10% SoC. The battery breaker
will eventually trip the battery at around 47V to protect the cells from undervoltage.

The weight of each model is given in the tables. The Freedom Lite Home 5/4, 10/8 and
15/12 models can be manually lifted by two people onto its hanging points. The larger units
may 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 located on the top right-hand side of the casing
and vary in number according to the model [2 in Figure 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.

2) Max load duration – 30 seconds per 40 second cycle. 1.5 x Max overload can be handled for 5 seconds.
3) Fly Leads 1,8m long, power cable Red = Positive, Black = Negative, conductors in table refer to one electrode i.e. per
positive and negative connections
4) End of Life (EoL) defined as cell dropping to 60% of Beginning of Life (BoL) capacity for expected life and 70% of BoL
capacity for warranty. This warranty applies to Lites sold after 1 September 2019. For Lites sold prior please contact
Freedom Won for warranty information.
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 Type B “printer” plug [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 obtain the correct cable to allow Freedom Won or the
distributor to program batteries remotely on behalf of the installer via the installer’s
Windows laptop, if necessary. One cable is provided with each battery.
An error reset button [8 - concealed] is positioned adjacent to the USB plug.
Freedom Lite is also fitted with a State of Charge (SoC) display [9], which includes a red LED
error indicator [10] and below it a “low power” indicator.
Figure 2.2 USB Type B “Printer” Cable for Programming Freedom Lite
The ON button [11] and OFF button [12] are located beside the SoC display.
The Lite Home range can be wall mounted, but if a sturdy wall is not available floor
mounting is an option. The Lite is supplied with a securing tab at the top in the middle as
part of the rear cover to secure the battery against the wall for floor mounted installations
to prevent it from tipping over [13]. Note: this tab must not be used to support the weight
of the Lite, only to ensure it does not topple over when mounted on the floor. This tab is not
suitable for securing the Lite in a moving vehicle where vibration could occur.
Freedom Lite Installation Manual Revision 13
P a g e 7 | 31
All Lite’s have feet as standard, whether needed or not [15].
A hard point is supplied on the top for the 15/12 and 20/16 models [14] for inserting an eye
bolt that can be used for hoisting the battery onto the wall mountings. The Lite 30/21 and
above are supplied with permanently installed eye bolt(s).
3. 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:

The external isolating device required for installations in Australia should be designed to
withstand these fault levels (short circuit currents).
4. Transport, Handling and Mounting
The Freedom 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 Freedom
Lite Home 5/4 and 10/7 models are easily handled by two people. The 15/11 and 20/14
models may be manually handled by four or six people. The 30/21, 40/28, 60/42 and 80/56
models must be handled with care by a forklift or pallet jack of the required lifting capacity
rating.
If it is necessary to transport the larger units (typically 40/28 and larger) up or down
multiple stairs in order to get them to the point of installation in the premises it may be
preferable to deliver the unit with the lithium cell modules separate and then Freedom Won
will fit them into the unit on site. This must be arranged with Freedom Won at the time of
order placement and will attract a nominal fee for labour plus transport and
accommodation where applicable. This service is not available in all countries. Please
enquire with Freedom Won Sales.

The “Home” series is designed for wall mounting 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 predrilled 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 5/4, 10/7 and 15/11 models are hung using M8 bolts whilst the 20/14 and
30/21 models are hung on M10 bolts. 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 3.1 Bolt Mounting Keyhole on Rear of Lite Casing – floor mount retaining tab and
fitted eye bolt also visible
Eye 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 (excluding 5/4 and 10/8, which can be lifted manually). The eye
bolt(s) on the models up to the Lite 20/14 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.
