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 80/64)
Freedom Lite Commercial: Ten models available ranging from the 100kWh model (Freedom Lite
Commercial 100/80) up to the 700kWh model (Freedom Lite Commercial 700/560).
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

Backup storage or UPS mode
Off Grid plant with storage and solar
