Introduction 

This  manual  is  intended  to  aid  an  installer  with  the  installation  and  commissioning  of  the 
range of 

Freedom LiTE Marine 

lithium iron phosphate (LiFePO4) energy storage models.  

This  document  is  not  intended  to  provide  detailed  information  of  the  inner  working  of 
Freedom  LiTE  that  is  not  relevant  to  a  person  that  is  performing  the  installation  and  final 
commissioning.    Supplementary  information  relating  to  the  programming  of  the  built-in 
battery  management  system  and  advanced  troubleshooting  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.

Product Description 

The  Freedom  LiTE  technology  is  available  in  various  standard  sizes  to  meet  all  residential, 
commercial, and industrial applications ranging from 5kWh to 800kWh.  Larger systems are 
accommodated  by  installing  multiple  units  in  parallel.    Models  designed  for  mobile 
applications including Marine and Mobility are also included in the range line up.  

Freedom Won offer the following ranges in LiFePO4 technology: 

 

LiTE 12V 

 

eTower  

 

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  

Please refer to the manuals specific to the applicable range required.  

This manual covers the models of the LiTE Marine range from 5kWh up 30kWh.  

The LiTE Marine range of lithium  batteries 

offers 13V, 26V and 52V options to suite ‘12V’, 

‘24V’ and ‘48V’ systems respectively.  These 

models are specifically designed to provide high 

end  energy  storage  performance  to  the  boating  industry.    It  is  designed  for  below  deck 
applications away from direct saltwater exposure.  For applications for open deck operation 
such as ski boats, please contact Freedom Won for a solution.  

The 13V and 26V options suit 

‘12V’ and ‘24V’ systems used in the marine industry.  52V is also 

available to accommodate land-based applications where moisture and corrosion resistance 
is desired such as houses located particularly close to the coast.
