AC180P turns off and unnecessary noise

Hello! I have two problems with my new AC180P:

  1. After first charge to 100% and after loss wall power - ac180p turned off and I was only able to turn it on manually after a few seconds.

  2. The starting of the fan is work on temperature up and revs up (and noice up), but not work when the internal temperature drops (cold air comes out), but after turn off and turn on ac180p noise gone for few hours

@BLUETTI @BLUETTI_CARE, can you help me?

Today I had two shutdowns at 100% and wall connected in UPS mode. After the second shutdown I received error e092.

The second problem with noise reproduces only when the wall power is turned off

@Grigoriy Please update the new firmware to test. Looking forward to your update.

After update problems gone and now it is all ok, thanks!
