may also be used. This charge should increase the
battery voltage to prevent further tripping. This
problem should not occur if the inverter control is
working properly.
If this does not work, it is because the battery has been
discharged too deeply and will need to be reset
remotely by Freedom Won by accessing your Windows
PC connected to the battery. The PC must have Anydesk
installed and you will need the RS232 adapter to
connect the PC to the battery. Please contact Freedom
Won.
If the SoC is at 100% it is most likely the tripping is
because the battery has been over charged. Leave the
battery for an hour and then try again. Ensure that all
charging sources are disconnected or disabled. Once you
have got the battery on again investigate what is wrong
with the setup that is causing the over charge events.

I have switched off the main
battery breaker switch to prevent
discharge of the battery but the
SOC display lights are still on.
The BMS and SoC display receive power directly from
the battery and therefore the “OFF” Button must be
pressed to switch off the internal electronics.

The inverter will not come on
even though the inverter switch
is selected to ‘on’.
The enable command may not be coming from the BMS
or the communication/control cable may not be
properly connected to the inverter, or the inverter may
not be properly configured to deal with the enable
command. If you are using a hard-wired interface (using
a relay) you can confirm whether the enable relay is
energised. If not, then a battery parameter is outside of
limits, most likely SoC or cell voltage, or there is a critical
error on the BMS. Try resetting the BMS. If this does not
work charge the battery and the inverter control should
be re-enabled. If the relay is energised, then the
problem lies with the control wire connection to the
inverter or the inverter setup. Refer to the inverter
manual or setup information to ensure that you have
connected and set up the inverter properly.
If you are running on a CAN Bus control with a
compatible inverter and you are not observing the
correct enable response from the inverter check 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
