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 II
GX, and Quattro inverter/chargers, Solar charge controllers (VE.Direct and VE.CAN), and
controllers (Color Control
The Freedom 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 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 system is suitable for all applications, namely:
Grid Connected with solar and storage including continued operation in grid outage
consumption mode)
Backup storage or UPS mode
Off Grid plant with storage and solar

For further details pertaining to the setup of the Victron equipment not pertaining directly to the Freedom Lite interface please refer to the various manuals available on the Victron Energy website eg.
  • Page 4 55.0V and 55.8V. This advanced feature is only available from Freedom Won and allows superior system control and optimal battery management. The GX-device uses this set-point to control the real time operating or target voltage of the inverter/charger devices and the MPPTs.
  • Page 5 The inrush current when switching on the battery breaker onto the DC bus is huge. This can cause damage to the breaker over time. So it is a Freedom Won requirement that the DC bus is pre-charged before switching on the battery. This is achieved by switch on the AC input to the inverters – the inverters will use the AC power to pre-charge their capacitors.
  • Page 6 CAN Bus from the devices on Victron's VE.CAN bus. The Color Control GX has a single CAN bus and thus this split cannot be achieved. Therefore, CCGX cannot be used in systems with multiple Freedom Won batteries. In such cases, MPPTs must be swapped out for VE.Direct versions and additional ports can be provided with a USB hub (See “Extending USB ports by...

In order to do this on the Ve CAN MPPT’s select the User Defined option 8 battery type as this allows adjustment of the charge voltage setpoints. Adjust the maximum current on the MPPT’s to ensure that the combined total charge power cannot exceed the maximum rated charge current for the Lite or Lite’s in the system.
