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.
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.
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.
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.
