Freedom Lite Home and Business HV Installation Manual Revision 1
P a g e 2 | 25
1. Introduction
This manual is intended to provide assistance to an installer for the installation and
commissioning of the range of Freedom Lite Home and Business HV and HV+ 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 third party 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 Home and Business HV
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 HV and 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 and HV+ models vary in voltage from 153V nominal up to
614V nominal. The Freedom Lite HV and 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 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 Lite Home and Business HV and HV+ range.
There are six primary, as included in the table, but some models are available in two
voltages as distinguished by the suffixes HV and HV+ on the model name. 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 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 plastic feet for the 40/32 and
aluminium feet with plastic pads on the underside for the 60/48 and 80/64. 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 2 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 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 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
2020
The ON button [11] and OFF button [12] are located beside the SoC display.
The Lite Home HV range can be wall mounted, but if a sturdy wall is not available floor
mounting is an option. The models 30/24 and upwards are supplied with a securing tab at
the top in the middle as part of the rear cover to secure the battery against the wall 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.
All Lite’s have feet as standard, whether needed or not [15].
A hard point is supplied on the top for the 15/12HV and 20/16HV 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 15/11HV
and 20/14HV models may be manually handled by four people but are best handled by a
pallet jack or forklift if available. The 30/21HV, 40/28HV, 60/42HV and 80/56HV 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 cells 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 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 15/11HV and 20/14HV models are
hung using M8 bolts whilst the 30/21 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 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. The eye bolt 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.

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.
