I have had the same problem… a reboot did fix it …. For now at least

47

@dimko Sorry that I see this till now. Did your AC200MAX update the firmware finally?

49

@veryetti1 I’m sorry your AC200MAX can’t receive this firmware, please contact the after-sale support to repair the screen.

50

@BLUETTI_CARE I don’t know why, but there still no 4008.09 available for installation via your application. It is still shown that 4008.03 installed and no new updates available :expressionless:

51

@dimko Your machine version may not be able to get this firmware update, please contact the after-sales department to replace the screen.

Hi BLUETTI, I have the same problem. The touch screen is working fine except for switching AC and DC on or off.
Worked fine until this afternoon.
Here are my serial and version numbers
Can you please advise!
Thanks

@Dabixi We will push a firmware for you to test in 24 hours.

Thanks for looking into this!

56

Upgrading ARM to 4030.17 did the job and I can switch power on/off with the touchscreen.
Thanks for the quick response!

Hello Support Team,
Same problem with my AC200Max EU 230v unit. Started 3 days ago.
Cannot operate AC/DC from the touch screen, it works only with Bluetooth App.

Can you please provide a firmware update to me?

@Zhyrnov I 'm sorry your AC200MAX can’t receive the firmware, please contact the after-sale support to repair the screen.

60

But why the firmware update works for one AC200Max units and doesn’t work for others?
What’s the difference? I don’t get it…

61

@Zhyrnov The machine versions are different. I’m sorry for the inconvenience.

62

Got the same issue :frowning_face: Yesterday it just stopped working and update didn’t solve it… that’s really disappointing since I don’t have service close to me.

Another issue I’ve just noticed - left it charging overnight and it was charging… When I last checked it was something like 80%. But in the morning it shows 59% as it was when I connected it.

64

I contacted the Support Team, and the issue with my unit was resolved through a firmware update.
Thanks.
