  • Page 2: Product Description

    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.
  • Page 3 Freedom LiTE Installation Manual Revision 14 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.

  • Page 9 Freedom LiTE Installation Manual Revision 14 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 is not supplied with the LiTE 15/12 and 20/16, one must be on hand for installation and can be removed after installation (ensure that you have one M12 x 1,75 thread eye bolt rated for 450kg or more).

  • Page 12 Freedom LiTE Installation Manual Revision 14 Caution: 1. Great care must be taken to ensure that the Rawl Bolt has properly located into the narrowed section of the mounting hole before removing the support. 2. Handle the Freedom LiTE with great care when lifting and manoeuvring. It should remain either lying flat on its back, or vertically upright (it should not be placed upside down or on its front face.
  • Page 13 Freedom LiTE Installation Manual Revision 14 Where multiple LiTE batteries are installed in one system, the spacing between each battery should not be less than 250mm. The LiTE should be installed at least 500mm away from a heat source such as inverters, charge controllers, boilers, or flues.
  • Page 14 Freedom LiTE Installation Manual Revision 14 DC Bus Design Notes 4.2.1 DC Isolator 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.

  • Page 19 Note that the Freedom LiTE plug uses pins 7 and 8 for CAN H and CAN L. If your inverter is not included in this table, please contact Freedom Won for assistance. All BMS interfaces above operate at 500kbps baud rate except for Ingeteam, which operates on 250kbps.
  • Page 20 Freedom LiTE Installation Manual Revision 14 Parallel Configurations It is permissible to connect up to 20 Freedom LiTE’s in parallel provided that the Freedom LiTE model size used is the same throughout. It is however more cost effective to purchase one larger Freedom LiTE model than connecting multiple units in parallel.
  • Page 21 Freedom LiTE Installation Manual Revision 14 Figure 4.3 Picture Showing 2 x RJ45 Sockets for CAN Bus Figure 4.4 CAN Bus Connection Example with Four LiTEs Freedom LiTE batteries can configure themselves automatically for master and slave configurations with up to 20 batteries. No programming is required, simply connect the CAN Bus cables and switch on the LiTE’s.
  • Page 22 If the master LiTE trips one of the slaves will take over as the master automatically without any interruption of service. Freedom Won offers a fair trade in on Freedom LiTE’s on the purchase of new units, which is an option for somebody wishing to expand their battery capacity instead of installing parallel units.
  • Page 23 Freedom LiTE Installation Manual Revision 14 Fig 5.1 “ON” and “OFF” Buttons Settings Required for Setting up Inverters and Charge Controllers The maximum and continuous discharge currents for the respective models are provided in Table 2.1. For charge current settings refer to the charge current limit. An average recommended charge current is one third of the continuous rating of the battery.

  • Page 24: Warranty And Repair

    The Freedom LiTE is sealed with a tamper proof warranty seal. It may not be opened by anyone other than Freedom Won and installers or repairers that have been explicitly approved by Freedom Won. The warranty on the unit will be void if the seal is damaged or missing.
  • Page 25 Freedom Won may arrange for an on-site service or for collection of the unit for servicing at our facility. This will be mostly determined by the geographic location, ease of access to or removal of the unit, and size of the unit.
  • Page 26 Freedom LiTE Installation Manual Revision 14 • Temperature of the environment – ensure that the environment in which the battery is operating (battery room) is maintained as closely as possible to 20°C. Avoid allowing the ambient temperature to fall below (zero) 0°C or rise above 30°C. Operation (and storage) of the battery above 30°C will substantially reduce its service life.
