Victron & Freedom Won LiFePO4 batteries -
Freedom Lite
Introduction
Freedom Won (www.freedomwon.co.za) produces two ranges of LiFePO4 batteries for 48V systems:
Freedom Lite Home and Business: Eight models available ranging from the smallest 5kWh
model (Freedom Lite Home 5/4) up to the 80kWh model (Freedom Lite Business 80/56)
Freedom Lite Commercial: Ten models available ranging from the 100kWh model (Freedom Lite
Commercial 100/70) up to the 700kWh model (Freedom Lite Commercial 700/490).
Note: Refer to Freedom Won website for detailed specification sheets covering all models
These Freedom Lite batteries are fully compatible with the Victron Multiplus, MultiPlus II, Multiplus GX,
and Quattro inverter/chargers, Solar charge controllers (Ve Direct and Ve CAN), and system
controllers (Color Control GX, Venus GX, and Octo GX).
The Freedom Lite batteries contain an advanced battery management system (BMS) that
communicates, using a CAN Bus protocol, with the Victron Venus device, which in turn communicates
as required to the other Victron devices on the system.
All Freedom Lite models can be connected in parallel with other models of the same capacity, where
one Lite (Master) communicates with the Venus 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 system is suitable for all applications, namely:
Grid Connected with solar and storage including continued operation in grid outage (ESS or self-
consumption mode)
Backup storage or UPS mode
Off Grid plant with storage and solar

CAN Bus communication from the Freedom Lite battery. Note: If a system includes one or more Ve CAN MPPT’s it is necessary to request that Freedom Won dispatches the Lite from the factory with a profile accommodating 250kbps BAUD rate for the CAN Bus (the standard is 500kbps). -

55.0V and 55.8V. This advanced feature is only available from Freedom Won and allows superior system control and optimal battery management. The Venus device uses this setpoint to control the real time operating or target voltage of the inverter/charger devices and the MPPT’s. -

Likewise, the MPPT’s will stop producing power to the DC bus. CAN Bus Wiring The connection of the Lite to the Venus device is extremely simple. A standard straight through CAT5e Ethernet cable is required of the desired length, with one end plugged into one of the RJ45 sockets on the Lite and the other end plugged into one of the CAN sockets on the Venus device. - Page 6 Last update: 2019-05-05 13:16 battery_compatibility:freedomwon https://www.victronenergy.com/live/battery_compatibility:freedomwon ☛Set the Shut-Down, Low Restart, and pre-alarm voltages (the pre alarm only activates the low battery LED on the inverter and serves no other purpose in this setup. The Shut Down and Low Restart voltage settings are usually overridden by the commands from the Lite but offer redundancy in instances of loss of communication and therefore should still be set correctly) ☛Charger Settings (set Battery Type as Lithium Iron Phosphate after selecting Lithium Batteries).
