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.

II. (150V to 300V)| Freedom Lite Home and Business HV| Ingeteam| Ingecon Sun 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.
