Just received by EB3, and am charging in quiet mode, but it is very loud for a small system.
What is the issue Bluetti?
River 2 has no issues like this…
This should have been fixed by now.
@dbocz What is the temperature? And what device did you load with? The start of the fan is closely related to many factors.
Room is 21 celcus.
Charging AC Sinlent 108 watts.
AC output 28 watts.
Low in and out, so why should the fan run?
