turn it so far out that there is less than the full thread
length engaging on the internal locking collar.

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 on the SoC
display.
If voltage is still not present with the breaker switched
on it is possible the breaker has been damaged – please
contact Freedom Won

The BMS (indicated by battery
SoC display lighting up) does not
stay on after the ON button is
pressed and released
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.
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.
4.
If the BMS still does not switch on, please
contact Freedom Won or Authorised Distributor
5.
Releasing the ON Button to soon – hold the ON
Button in for at least 5 seconds before releasing.

The main breaker switch keeps
tripping each time I attempt to
switch it on
There are several potential causes:
1.
The Battery Management System has not been
switched on. The ON button must be pressed for
5 seconds. On release the SoC Display must
remain illuminated.
2.
High inrush current on certain inverters – First
preference is to pre charge the DC bus by
switching on the solar charge controllers if
present and in daytime. If this is not possible
switch on the AC feed into the inverter and
switch on the inverter. Some makes will then
pre charge the DC bus. You can also use a pre-
charge resistor for this. If this does not work
after the second attempt investigate the other
options.
