Can not change AC on/off and DC on/off bluetti ac200max

Hi, I can not chance DC on/off or AC on/off on the display.
I can change it only through my mobile phone app.

Whenj it is AC or DC is on, I can not change it over the Display to off. Same when AC or DC is off, the Display works well but AC or DC stays on on or off.

What can I do? Thanks. Guido

Hello @n66dles , is the AC200MAX display does not respond when pressed, or the screen does not turn on at all?

Similar Problem.
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.

Can you help me?

Thank you,

Same is happening to me, but with my EP500 Pro. I can only change limited settings from the lcd panel. I am forced to use the phone application.

The same, it stopped working a few weeks ago after updating my iPhone Bluetti application to the new one.
