The Freedom Lite Home and Freedom Lite Business range from Freedom Won offers the long

overdue next generation energy storage with quantum increase in service life and operational

efficiency at a fraction of the life cycle cost compared to other energy storage types.

Expensive?

Lithium Iron Phosphate batteries might seem expensive when compared to lead acid batteries, but

this is not true. A proper scenario comparison will reveal that the purchase costs are very similar

and any marginal premium for a LiFePO4 battery is more than compensated for by longer life, and

a very high efficiency. The high efficiency means that far less energy is wasted and that the solar

array can be 30% smaller to achieve the same results. In general - because of the high DoD

capability and high efficiency the ampere hour rating of a Freedom Lite Battery need only be 35%

of a lead acid battery to give the same useful output - this is important when comparing costs

between the two technologies.

Compact, Integrated and Attractive

The Freedom Lite (LiFePO4) Home and Business batteries range covers the varying needs of

home owners and small to medium business premises with models ranging from the Freedom Lite

Home 5/4 to the largest Freedom Lite Business 80/56. The “Home” models are wall mounted

offering the ultimate in space saving. All models are integrated with the necessary Battery

Management System (BMS) and control circuitry to protect the pack and interface with the

seperately supplied external inverter/charge units. The standard enclosure is powder coated in

white.

Control Interface for Compatible Inverter/Charger Units

The BMS provides relay and analogue outputs and CAN Bus for independent control of (and

communication with) the inverters and solar charge controllers through a multi core cable and

Ethernet cable respectively. Charge and discharge current limits and state of charge values are

some of the important parameters transmitted by the BMS. The Lite is configured prior to delivery

for the applicable inverter brand.

Power Interface

Suitably sized positive and negative cables are provided for connecting the 48V DC cables to the

inverter and solar charge controller. The DC circuit is protected with a shunt trip circuit breaker.
