Hello dear community, i bought my eb3a about 6 month ago couple days ago it started making some buzzing sound when inverter was on, it used to just click and turn on, now it has slight buzzing sound when idle and increases with load, do i have to worry about anything here or its normal ?
I barely used this unit AC maybe 10 hours max over 6 month and this is concerning
I have read that is fan noise but fan is not even running so i dont think its the fan, i know some inverters have some noise but when it was new it never made a noise it was dead silent so i wanna make sure everything is fine
@BLUETTI_CARE would you kindly check this post <3
Edit: I made some experiment at 0 load there is a buzzing sound at 40-50watts it increased (doubled) at 90-185watts it went lower (its like noise stabilized) so not sure
