Thank you very much. The update was successfully installed.
I have now fully charged the station.
Now I will unload it and load it again.
In between document all data
Whether it has brought something, I will report.
Hello Bluetti,
I did not receive any update in the last 12h.
Can you please provide the update.
Best regards,
Matthias
@6ender You need to login to your account and connect your device with Bluetooth to upgrade.
Could you please check again? Thank you!
Hello Bluetti,

Still no update available in the app.
Best regards,
Matthias
logged out and in again several times… and still no update available… 
Best regards,

@6ender Sorry for the late reply. If you didn’t receive the update firmware notification, we suggest you do the machine power cycle first. (Empty the power and then fill it up with AC, cycle twice.)
If the problem still exists, Then you need to contact customer service at service@bluettipower.com to return the machine for repairing
Hello Bluetti,
I’ve been monitoring the station for a few days now and haven’t noticed any further problems so far. everything works as it should and no voltage drops have occurred so far. Thanks for your help.

My AC200Max is loosing all power over night. No output. S/n 22210025459
05.
@Jonathan Have you tried to calibrate the machine?
First discharge the machine to 0%, then charge it to 100% via AC. During this time it needs to be charged continuously, with no loaded.
Please follow the above method at least twice to see if the problem can be improved.
If the problem persists, please let me know the version number of your BMS by the way.

Hello Bluetti,
after a month of observation, the error occurs again.
Yesterday evening (01.05.2023) with 48% switched off.
Today (02.05.2023) when turning on independently (solar charging) it is at 75%.
It seems that the error has not been fixed. 3 days before, the station was completely discharged and charged again to 100% with the charger and then discharged again to 0%. In the last 2 days the station was charged to 75% with solar and discharged to 48% as described above. Now it is again 75% which can not be true.
How to proceed to solve the problem?
ARM: v4008,03
DSP: v4005,07
BMS: 1017,03
