that the CAN High and CAN Low wires are
connected properly (ensure that you have the High
and Low the right way around and that you have
connected the two end of line 120 Ohm resistors in
the applicable places). If this is not the problem,
then you need to confirm that you have the right
CAN profile programmed onto the BMS for the
inverter in use (baud rate or CAN messages may be
set for another inverter brand) or that you have
configured the inverter or system controller
correctly. Contact Freedom Won or your Authorised
Distributor for assistance if you need help setting up
the inverter for the communication used i.e., CAN
bus or hard wired.

The charger will not come on even
though there is power on the AC
input of the inverter and the charger
is activated in the inverter settings
The battery might be full. Try discharging the
battery for a while and observe if the charger then
comes on. If not, then the fault-finding process is
similar to above.
8
The Freedom LiTE error light keeps
illuminating after each reset
If the battery voltage is within limits this should not
ordinarily occur. Contact Freedom Won or an
approved installer for assistance with determining
the problem. If the main breaker does not trip it is
not a critical error and you may continue using the
battery while you make, contact for assistance.
9
The pack voltage and SoC is within
limits, but the main breaker still trips
seemingly at random
This could be caused by many things but is most
likely because the current draw is exceeding the
battery current limit setting. Measure the current
with a tong tester (clamp meter) while drawing your
maximum typical load to determine if you are
exceeding the rated current for the respective
Freedom LiTE model. If it is not the current causing
the trip it could be a weak cell or extreme
temperature of the surroundings. Both are unlikely.
If the problem persists, contact Freedom Won.
10
Slave battery keeps tripping
The slave batteries may trip if they have not
received communication from the master for more
than 5 seconds. Check the CAN cables for faulty
plugs or damage. Ensure that the termination
resistors are fitted.
11
Master battery only reflects its own
current on the system controller
Check the slave CAN Bus cables for faults and two
termination resistors are fitted.
12
The alternator does not charge my
battery
If you are using a remote enable regulator, ensure
that you have wired the relay to connect ignition
power to the regulator control wire input when the
relay is closed by the BMS. Ensure that the relay is
in fact closed. If it is open and the battery is at 100%
SoC and at or near max charge voltage it is likely the
alternator is not charging because the battery
cannot take more charge. The relay should close
again after a 15-minute interval or if the SoC drops
below 99%.
