  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

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!

Have same issues with my new ac180p.

25-30w load and power station make some buzz noise and low fan speed sound. Sometimes fan can start on maximum with same 25-30w load. After off/on station stay silent.

Same problem, same behaviour, but with .04 firmware. Fans are too loud (probably their maximum speed). My case - just MacBook (20-50w), dc port, without charging.

@BLUETTI_CARE likely global issue

Thanks

Hi, I have the same problem, after loss of AC input (wall power) my AC180 shuts down and must be manually re-started. This diminishes the purpose and advantage of having reliable backup power.

@BLUETTI_CARE Any new firmware to resolve this problem?
