I have this product for a week or so and it worked normally. But today, after 5-10 min after plugging in refrigerator (Bluetti was not charging) it started emitting more noise than usual - it was louder and probably on lower frequency. Display wasn’t responding, so I turned Bluetti off by button. After that AC/DC On buttons are not working - so I can try to turn it on, but is would still show “off” and no output detected.
Refrigerator power consumption is around 160W at peak and less than 50 normally.
Any suggestions how to fix is appreciated.
