E-Tower LiFePO4 Battery 5kW 48V
Freedom Won produces various ranges of the popular eTower and Freedom Won LiTE battery to suit all applications. The respective battery ranges available are as follows:
- eTower
- LiTE Home and Business
- LiTE HV Home and Business
- LiTE Marine (13V, 26V and 52V)
- LiTE Mobility (golf carts, forklifts etc)
- LiTE Commercial (including Lite Commercial HV and HV+)
- LiTE Industrial
For the Freedom Won general purpose 12 V LiFEPO4 batteries not covered here
please refer to the 12V battery specification sheet for more information.
The focus of this guide is to summarize the inverter and allied equipment
brands that are certified to be compatible with tower and Freedom LiTE
batteries. The interface option covered relates only to the CAN bus or RS485
communication option. For interfacing with analogue and relay drivers in the
Marine range please refer to the Lite Marine installation manual.
The CAN bus or RS485 interface is not the only consideration when determining
the marriage suitability of an tower of LiTE and an inverter – the operating
voltage and power capabilities must also be matched.
All CAN or RS485 networks must contain two 120 Ohm termination resistors;
every LiTE is supplied with one resistor to fit into the second RJ45 CAN Bus
socket on the battery, some inverter systems require the addition of another
resistor and some have one built in. The eTower master module that the
inverter CAN Bus or RS485 will be connected to has a built in termination
resistor on the CAN Bus and RS485.
Some systems require a specially made RJ45 cable to accommodate varying pin
configurations when connecting to the inverter – these can be purchased from
Freedom
Won or made by yourself by referring to the LiTE manual for the pin
configuration. The eTower batteries are all shipped with a selection of
cables that provides a solution for most inverters on the market and therefore
purchasing separate cables is not necessary.
Some inverter systems require a special profile on the eTower or LiTE. If you
require this, please contact Freedom Won for assistance.
Refer to the respective eTower or LiTE installation manual for further
information on CAN bus communication.
The natural classification for laying out this guide is to split the eTower
and LiTE ranges into the following categories based on their nominal operating
voltage:
I. 52V and below (this means 13V, 26V and 52V)
II. 150 to 300V
III. 300 to 600V
IV. 600V to 800V
Table 1 provides the inverter and interfacing information for all inverters
certified by Freedom Won in each of the above four categories.
Inverter brands not included in Table 1 have not been certified by Freedom Won
for the CAN bus or RS485 interface. Should you have another brand of CAN bus
or RS485
compatible inverter that you would like to connect to an eTower or LiTE please
contact Freedom Won, we would be glad to assist.
There are also a few inverter brands that are not CAN Bus or RS485 enabled and
hence have no way to communicate with the eTower or LiTE. These inverters will
also work in a system with the eTower or LiTE, but some functionality will be
lost because of the lack of information and commands available from the
battery. For example, the true SoC of the battery will not be available on the
inverter, and the battery will also not be able to stop charge or discharge
should it be necessary. The battery will trip to protect itself if this
occurs, so there is no safety concern, only a matter of inconvenience. For new
installations Freedom Won recommends selecting a CAN Bus or RS485 lithium
battery compatible inverter. For retrofits where an inverter without CAN bus
or RS485 already exists, the eTower or LiTE can be used, provided that the
inverter voltage setpoints are set up correctly – contact Freedom Won for
assistance if the eTower or LiTE manual does not provide you with enough
information.
The Freedom Won eTower comes with the following inverter cables included:
- CAN Bus Comms cable for Victron inverters
- CAN Bus Comms cable for Type 1 inverters (eg. Sunsynk, Solis, Goodwe, Growatt, Revo)
- RS485 Comms cable for Voltronic/Axpert inverters
Refer to the respective inverters’ installation manual to confirm connector
type required.

LiTE| Note: operating these inverters on 52V is possible but the battery
current is limited by the inverter to 50A and therefore the maximum battery
power available from the inverter is about 2.5kW. Standard Ethernet cable can
be used for the CAN bus – the inverter end has no plug, only wire terminals
(see Lite manual for the cable configuration)
Non-Standard “Ingeteam Profile” required on LiTE No additional resistor
required
Note: The Lite cables will not fit into the terminals directly on the Ingeteam
Inverter as the terminals are too small. Note: These inverters cannot be
connected in parallel or 3-phase owing to limitations to the Ingeteam
firmware. eTower is not compatible.

Storage 1Play 3TL and 6TL| The original Freedom Lite Home and Business HV
range was specifically designed for the Ingeteam inverters. The Ingeteam
inverters are very efficient and compact covering high performance for a
residential solution – full power is available from the inverter when
operating on battery owing to the higher DC voltage.
Standard Ethernet cable can be used for the CAN bus – the inverter end has no
plug, only wire terminals (see Lite manual for the cable configuration)
Non-Standard “Ingeteam Profile” required on Lite
No additional resistor required
The Lite Home HV cables will fit into the terminals on the Ingeteam Inverter
as the terminals HV cables are much smaller owing to lower current.
Note: These inverters cannot be connected in parallel or 3 phase owing to
limitations to the Ingeteam firmware.
