Expected Product Life
Freedom Lite is designed for optimal life cycle cost, which is a fraction of any other battery
technology available on the market, in particular from 25% to 35% of the lifecycle cost of
the range of lead acid and associated variants on the market. Please contact Freedom Won
if you would like more detailed information for comparison with lead acid batteries than
what is available on our web site.
Freedom Lite is expected to operate for 16 to 20 years (more than 5 500 cycles) in a daily
cycling scenario with an average of 80% DoD per cycle. For applications with occasional
cycling, such as for emergency backup, the service life expected is 20 years or more.
For applications where the cost per kWh delivered by the battery during its lifetime is of
prime importance (i.e. maximum return on investment) we recommend that the battery be
sized for an average cycle discharge of 50-60% DoD. In a daily cycling scenario such as for
optimal solar self-consumption and off grid systems the expected service life is then 20
years or more than 7000 cycles. The defined end of life in this instance occurs when the
battery capacity falls to 60% of the new capacity.

Troubleshooting Guide
Most issues with the Freedom Lite can be resolved using the guide below. If a problem
cannot be resolved after referencing this table please contact Freedom Won or your
approved Freedom Won supplier.

No Problem Description
Cause/Solution
1
The Freedom Lite has no voltage
on the main output cables
Check that you have switched on the main breaker
switch. Note – only turn this on once you are satisfied
that you have completed the installation and that there
are no DC or control wires that can short out or touch
ground or other wires. Also ensure that you are ready to
accept AC voltage onto the inverter output before
switching this breaker on. Also confirm that you have
energised the BMS first by pressing the “ON” button for
3 seconds and as evidenced by the lights illuminated on
the SoC display.
2
The BMS (indicated by battery
SoC display lighting up) does not
stay on after the ON button is
pressed
First switch off the AC output breaker to ensure that the
inverter cannot supply loads from the battery, then
review the following:
1.
Error light shows on the BMS – Check whether
the red error light is illuminated on the SOC
display when the ON button is held in. You can
try to reset the error by pressing the RESET
button for about 2 seconds while you hold the
On button in. This should clear the error and
