About Freedom Lite
Long Life High Performance Energy
The Freedom Lite Home and Freedom Lite Business range from Freedom Won offers the long overdue next generation energy storage with a quantum increase in service life and operational efficiency at a fraction of the lifecycle cost compared to other energy storage options.
Compact, Integrated and Attractive
The Freedom Lite Home range covers the varying needs of home owners and even small business premises with models ranging from the Freedom Lite Home 5/4 to the largest 30/21. These 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 separately supplied external inverter/charger unit – lithium cells can not be operated without a BMS. The standard Home enclosure is powder coated with white sides and face.
Control Interface for compatible Inverter/Chargers
The BMS provides digital potential free contacts for independent control of the inverter load and the charge from the main charger and solar charge controller through a multi-pin plug on the side of the module, which also includes pins for voltage sense and charge current control for compatible chargers. The BMS is fully configured prior to delivery.
Positive and negative studs 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.

Lithium Iron Phosphate Advantages
Lithium Iron Phosphate (Lite Home) batteries have several advantages over conventional lead-acid batteries:
High energy density: more energy with less weight High charge currents (shortens the charge period) High discharge currents (enabling for example electrical cooking on a small battery bank) Long battery life (up to six times the battery life of a conventional battery) High efficiency between charging and discharging (very little energy loss due to heat development) Higher continuous power available
A lead-acid battery can fail prematurely due to sulphation if it is left partially charged, fully discharged, or rarely fully charged for long periods of time. A Lithium Iron Phosphate battery does not need to be fully charged, has a wide operating temperature range and excellent cycling performance. They are therefore the battery for very demanding applications.
The typical energy efficiency (energy that can be taken out of the battery compared to energy required to re-charge) for lead acid batteries is ~ 70%. For a LifePO4 battery it is ~ 92% The final 20% charge for a lead-acid battery is particularly inefficient with efficiencies of ~ 50% and can take a very long time for the battery to become completely charged. In contrast a LifePO4 battery can still achieve 92% efficiency and so can be fully charged more quickly and using less energy.
Size & Weight
LifePO4 batteries save up to 70% in space and 70% in weight compared to lead-acid.
Lithium Iron Phosphate batteries are expensive when compared to lead-acid, but this is compensated for by longer life, size or weight considerations, superior reliability & efficiency.
Battery Management System
It is vital that the correct battery management system (BMS) is used to control the battery charging. This is important to actively balance the individual cells that make up the battery and prevent under or over voltage which can otherwise destroy the battery.
For Mines in remote places building a solar array with these cells as backup to run through the night and charge in the day is more economical than diesel generators if the operating lifespan is long enough – as it would be on a mine. Mines can be run off solar power for a lower life cycle cost than generators. Variants of this are also extensive i.e. for plants with poor power quality it is simple to install a battery bank that can ride an entire plant through a power dip or even for several minutes in order to allow for a controlled stop. To simplify this even further, plants with mostly VSD's running their machines can run the VSD's off DC power by connecting the standard VSD's via the DC link. This makes the VSD's immune to power quality problems and minimises damage that is so often caused by dips and surges.
Residential Off Grid Systems
Could offer total independence. A typical house can run completely from solar power with say a 6kW peak solar array and a 30kWh Freedom Lite battery pack that will last more than 10 years. The system can be sized to any capacity to suit the household demands and can run the house through two to three days of poor weather.
Residential Backup Systems
Eliminate the power outage frustration without a diesel generator. A 10kWh pack of Freedom Lite cells will operate a household during a power outage for a few hours and then will be charged up again when the power comes back on.
Telkom and Mobile Telecommunication Towers
Freedom Lite offers far superior performance to the lead acid batteries that the telecoms companies are presently using.
Power Quality Improvement.
Power users on a poor grid infrastructure plagued with dips and spikes can use Freedom Lite cells efficiently and cost effectively to smooth power supply even on high power systems.
Uninterruptible Power Supplies
UPS systems are notorious for the short lifespan of the typical lead acid batteries they use, especially if the batteries are kept in a high temperature environment. LiFePO4 cells are much less sensitive to high temperatures and can happily operate up to 45 degrees Celsius with no related drop in lifespan or performance. Freedom Lite cells can stand at full charge for lengthy periods without deteriorating.
Battery Tripping Units
Electrical sub stations require battery backup to trip the breakers if necessary when there is no grid power. Lead acid cells left at full charge will still deteriorate, which is a common problem with the batteries used to supply these tripping units. Freedom Lite cells do not deteriorate in such a scenario and only require discharging and recharging once every few months.
