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.

If the BMS still does not switch on, please
contact Freedom Won or your Authorised

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
