My Bluetti 200 Max is about 6 months old, and I can no longer change settings on the touchscreen.
It will not allow me to turn On or Off the AC or DC output, or change the screen time duration unless I use the App.
This problem started about 2 to 4 weeks ago when I went in morning to view the screen it was all
Jambled up. The unit should not have been low enough to turn off?
I started the charger and my screen became clear, but I could not turn the inverter or the DC output on.
Later fired up my app and noticed the app had been updated with new graphics, and I could turn things On or Off.
I need my touch screen to operate, if someone else needs control.
Thank you for responding,
Here are my current versions.
Serial number 2220000528809
I tried updating the firmware, but not sure that it updated?
It never acknowledges that it is updating?
I tried hitting the update button on the first page that mentions firmware update, and tried hitting the button on the second page that says firmware update.
Is there a video for updating the firmware?
Thank you very much for your help.
hello, I have the same problem with my A200Max 230V EU version. I can make partial changes to the touchlcd, but I do not get them displayed.
also a factory reset, ac-out on/off etc… I can not trigger.
With the APP I also unfortunately can not do a firmware update, it only shows the installed ones. What can I do?
DSP Version: 4005.07
ARM Version: 4008.03
BMS Version: 1017.02
HMI Version: 6037.03
Is there a way to completely de-energize and reset the electronics?
