2.3.3 App reports:
“
The battery
system may be
busy, please try
again later
”
Battery-Box is busy (e.g. the battery could be updating the
firmware). Please wait 10 minutes and try again.
2.3.4 Proper restart
2.3.5 Close and
restart BC APP
If BC APP does not react anymore after some minutes loading
during the update process, close (close the program completely)
and restart BC APP. Or try with BCP (section 2.9)
2.3.6 BMS Version not
updated
BC APP will only update the BMU. The BMU will update the BMS,
which can take up to 30 minutes.
If the BMS Version is not updated after 30min with stable inverter
communication, follow the below Process:
1.
Update Firmware through BC APP again
2.
Restart the system
a. Switch off the Inverter first, then switch off the battery second
(Press LED for 5 seconds)
b. Wait for 2 Minutes
c. Turn on the Battery first, then turn on the inverter second
3. Wait for 30 Minutes
4. Check BMS Firmware Version again with App. If Version is still
wrong, do the update process again (if possible with another
mobile device).
5. Note: if Voltage of Battery is not shown in BC APP, the update
will not be transferred to BMS. Make sure the BMU recognizes
BMS properly.
Note: Whenever the configuration via
BC APP
/
BCP
is changed,
a restart of the battery is necessary to make sure that all changes
come into effect.
1. Switch off the battery (Press button on BMU for 5 seconds until
all batteries switch off. Note: if the modules do not turn off then,
something is wrong in the top LV Flex Lite module<>BMU
connection.Replace comm cable and try again.)
2. Turn on the Battery (button on topmost battery)
