    5kWh up to 80kWh. Please refer to the manuals specific to the other ranges. The standard Lite voltage is 52V nominal (to suit 48V systems). The Freedom Lite HV range is designed for specific Higher Voltage inverters such as those from Ingeteam (Ingecon 1Play 3TL and 6TL).
  • Page 3 Freedom Lite Installation Manual Revision 12 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.

The Freedom Lite Home 5/4 and 10/8 models can be manually lifted by two people onto its hanging points. The larger units require lifting equipment of varying degrees for handling and installation as explained later in this document.

  • Page 7 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 “low power” indicator.
  • Page 8 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...
  • Page 9 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.
  • Page 10 Freedom Lite Installation Manual Revision 12 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(s) on the models up to the Lite 20/14 can be removed after installation.
  • Page 11 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 3.4. A site assembled gantry with electric winch is shown in Figure 3.5. This gantry is available from Freedom Won as an accessory and is available with various gantry widths.
  • Page 12 2. Handle the Freedom Lite with great care when lifting and manoeuvring. It should remain either lying flat on its back, on a long side, or vertically upright (it should not be placed upside down or on its front face.
  • Page 13 Connecting the Freedom Lite Power Cables The Freedom Lite is simple to connect to the battery inverter. First of all you will connect the 48V positive and negative cables to the inverter terminals using the applicable lugs. Caution: Prior to connecting the positive and negative cables to the inverter be sure to check that the main battery circuit breaker is switched off.
  • Page 14 CAN it must first of all be equipped with a CAN interface as well as a suitable method of connecting the CAN wires. Further to this the Freedom Lite BMS must be programmed with a CAN messaging profile that is developed for the inverter or charge controller being used.
  • Page 15 (second) plug. These resistor plugs are available from Freedom Won (if you are using Victron then you can use the Victron supplied resistors). SMA, Imeon, Solax and Victron operate on this basis for example.
  • Page 16 Pin 6 on Inverter end or cable with a 120Ω resistor If your inverter is not included in this table, please contact Freedom Won for assistance. Parallel Configurations It is permissible to connect multiple Freedom Lite’s in parallel provided that the Freedom Lite model size used is the same throughout.
  • Page 17 (preferably the Master) can be connected to the inverter directly or the system controller, depending on the product brand. All Freedom Lite Home and Business models are shipped with hardware that enables them to be configured either as a master or as a slave.
  • Page 18 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 19 SoC level shown. Confirm at this stage that the error lite is not illuminated. If it is, contact Freedom Won. If the Reduced Power light is illuminated, do not be concerned, it should extinguish after the battery has been in operation for a few hours.
  • Page 20 The BMS inside the Freedom Lite will deal with an excessive spread of cell voltages by balancing them out using the cell tap wires attached to each cell and its internal circuitry. If a cell voltage does reach its limit the BMS will be forced to intervene.
  • Page 21 Freedom Lite Installation Manual Revision 12  52,0V for approximately 60% DoD  51,0V for approximately 70% DoD In non-CAN Bus systems fitted with DC solar charge controllers (SCC) the AC charger should stop charging at 53.5V to allow the remainder of the charge to be performed by the SCC.

  • Page 23 Once transferred to battery power the inverter will continue to operate until the BMS instructs it to stop on CAN Bus. This should only occur if the Freedom Lite has dropped to 10% SoC (90% DoD). The inverter will then not function off battery until either the solar charge controller has recharged the battery to at least 20% SoC and will thereafter continue to operate provided that the SoC remains above 10%.
  • Page 24 Several important settings must be correctly configured in the Color Control, Multiplus/Quattro, and charge controller. The latest firmware versions must also be installed in each case. Please refer to Victron manuals or contact Freedom Won for assistance with this. Guidelines at this link will also be useful: https://www.victronenergy.com/live/battery_compatibility:freedomwon...
  • Page 25 GTI need not be ‘throttled’ back. If it is not set up for feeding back to the grid and the voltage of the Freedom Lite has reached its maximum voltage, it will reduce the power delivery of the GTI to that which is equivalent to the consumption in the house at that time.
  • Page 26 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 27 Freedom Lite Installation Manual Revision 12 Expected Product Life Freedom Lite is designed for optimal life cycle cost, which is a fraction of any other battery technology available on the market, in particular from 25% to 35% of the lifecycle cost of the range of lead acid and associated variants on the market.

  • Page 29 If this does not work, it is because the battery has been discharged too deeply and will need to be reset remotely by Freedom Won by accessing your Windows PC connected to the battery. The PC must have TeamViewer installed and you will need the RS232 adapter to connect the PC to the battery.
  • Page 30 Freedom Lite model. If it is not the current causing the trip it could be a weak cell or extreme temperature of the surroundings. Both are unlikely. If the problem persists, contact Freedom Won.
