Table 14.1 Troubleshooting Guide (applicable to units with On and OFF buttons)
No Problem Description
Cause/Solution
1
The BMS (indicated by battery
SoC display lighting up) does not
stay on after the ON button is
pressed
1.
Error 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 and release. This should clear the error
and allow the BMS to stay on after releasing the
ON button.
2.
Battery has been discharged to critically low
level – remove all potential loads from the
battery and switch off the inverter(s). Then try
to switch on the BMS and then the breaker and
get either a Solar Charger of AC Charger to
charge as soon as possible – ensure that the
loads are switched off.
3.
Battery has been charged to critically high
voltage level – usually leaving the battery for an
hour will allow the cell levels to drop down
within acceptable levels and allow the BMS to
be switched on again. Ensure that the suspect
charge device is not able to charge the battery
until you have established by it is overcharging –
it could be that the CAN communication is not
set up correctly or in the absence of CAN the
relay control, or in the absence of relay control
the charge voltage setpoint could be set too
high.
4.
If the BMS still does not switch on, please
contact Freedom Won or your Authorised
Distributor for further assistance.

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 DC voltage onto the inverter before switching
this breaker on. Also confirm that you have energised
the BMS first by pressing the “ON” button for 5 seconds
and as evidenced by the lights on the SoC display.
Remember to push the breaker lever down first before
switching it on by pushing the lever upwards.
