Important: It is very important to read this documentation in full and carefully. Freedom Won battery warranties require that you have configured the battery correctly.
Please take special and careful note of the section below on "DC bus pre-charging".
Freedom Won () produces two ranges of LiFePO4 batteries for 12V, 24V and 48V systems:
conveniently and cost effectively over time. The eTower is designed primarily for systems that need to start with 5kWh initially with a view to growing the storage capacity over time in 5kWh increments up to 20kWh. The LiTE range is recommended for systems starting at 10kWh or larger than 20kWh.
This documentation makes use of values for 48V systems but values for 12V and 24V systems can be derived from below:
Note: Refer to Freedom Won website for detailed specification sheets covering all models
These Freedom Won LiTE batteries are fully compatible with the Victron MultiPlus, MultiPlus-II, MultiPlus-II GX, and Quattro inverter/chargers, solar charge controllers (VE.Direct and VE.Can), and system controllers (Color Control GX, Venus GX, Octo GX, Cerbo GX, CANvu GX, Maxi GX).
The Freedom Won LiTE batteries contain an advanced battery management system (BMS) that communicates via a CAN Bus protocol with the Victron GX device. The GX device in turn connects and manages the other compatible devices in the system.
All Freedom Won LiTE models can be connected in parallel with other models of the same capacity, where one LiTE (Master) communicates with the GX device as well as all the other LiTE''s in the system (Slaves).
The Victron and Freedom Won integration has been extensively developed and tested and is certified and supported by both companies.
The eTower can be paralleled up to 16 units. The recommended limit is 4 batteries in parallel because systems that require more than 20kWh are usually better accommodated by the Freedom Won LiTE range of high performance batteries. Systems that use a 250kbps CAN bus cannot be used with eTower, for example where they include the older VE.Can MPPTs (box-type).
The system is suitable for all applications, namely:
Figure 1 Typical Installation: Freedom Won LiTE 60/42 with Victron 15kVA Quattro and 3x Ve Direct MPPT''s
Figure 2 Typical Installation: 7 x Freedom Won LiTE Commercial 200/140 with Victron 12 x 15kVA Quattro and 10 x Ve Direct MPPT''s and 6 x Fronius ECO 27kW
This manual is intended to offer Victron specific guidance when designing, installing, and commissioning a Victron – Freedom Won LiTE system. For further details pertaining to the setup of the Victron equipment not pertaining directly to the Freedom Won LiTE interface please refer to the various manuals available on the Victron Energy website eg. Color Control GX manual. Likewise, for further information pertaining to the Freedom Won LiTE batteries, please refer to the Freedom Won LiTE installation manual available from Freedom Won (support@freedomwon.co.za).
NOTE: Certain older MultiPlus and Quattro models containing the smaller microprocessor chip (numbered 19 and 20) are not able to accept the version XXXX4XX firmware and hence are not compatible with the CAN Bus communication from the Freedom Won LiTE battery.
NOTE: If a system includes one or more VE.Can MPPTs please carefully read the section below on VE.Can MPPTs.
In all cases a GX-device running Victron's Venus OS is required to receive, process, and transmit the commands and information communicated by the battery to the Victron system.
In all cases the latest available firmware should be installed on the Victron devices. The Freedom Won LiTE may also benefit from a firmware update if the Victron firmware is being updated on an existing installation. Contact support@freedomwon.co.za for assistance with updating firmware on your Freedom Won LiTE.
The Freedom Won LiTE models are rated for specific maximum power discharge and charge levels. It is important to refer to the applicable Freedom Won LiTE specification sheet for the maximum inverter power that may be connected to each specific LiTE model. Do not exceed the maximum kVA values provided in the specification sheet for each respective model. For multiple units in parallel, the kVA rating for every LiTE in the system may be summed to provide the total allowable inverter installed power.
Further to above, the LiTE should be sized so as to provide adequate energy capacity in kWh to meet the load demands of the system and to receive most of the excess solar generation each day (for self-consumption installations).
NOTE: It is not permissible to install an inverter larger than stated in the LiTE specification sheet regardless of whether the "Limit DC Discharge Power" ESS feature in the GX-device is used. For instances where the grid is not available this power limiting feature will not operate and the battery could thus be overloaded, causing it to trip. The LiTE will also not be able to limit discharge power in the absence of a grid connection. Lastly, the LiTE contains a protection circuit breaker that is only rated to handle the power-up inrush current of the inverter for up to the capacity stated in the specification sheet.
The Freedom Won LiTE transmits, amongst others, the following messages to the GX-device:
All of the above information can be viewed in the Freedom Won LiTE device sub menus on the GX-device. Specific setup of the GX-device and the MultiPlus/Quattro is required to ensure the required control is implemented.
If the CAN bus cable is removed or damaged the Victron inverters will shut down within 5 minutes. This prevents continued operation in the absence of communication from the battery. Likewise, the MPPT''s will stop producing power to the DC bus.
