October 2, 20205 yr Hey, I just installed a Deye 5KW Inverter with a Dyness 3.6KWh Battery. However, since moving over all my electronics to the Load/UPS output, all my PC (and game console) PSUs now constantly make a buzzing sound. Is this normal? PS The inverter itself also makes a buzzing noise when running off the grid. Are the grid settings attached below correct? And/or does anyone perhaps know what may be causing this? Many thanks Kind regards Overblazze
October 29, 20205 yr Did you find a solution? I have the same experience with my recent installation. I use pylon batteries. I get the buzz sound, most audible on the microwave and less so on the fridge.

December 29, 20205 yr Author It's running on 50Hz. What does seem strange is my output voltage is 240v. Could this be the issue? Edited December 29, 20205 yr by Overblaze

Me and of of the guys who came to install were the only ones who could hear the sound. Everyone else, my family and the rest of the team that came to install, could not hear the buzzing sound. Maybe we have some strange super power laying dormant in us.
February 3, 20215 yr Author @melvin phutiYeah in my household, it's only my brothers and I that can hear it. Every other person I've asked can't hear it even with their ear right against it 🙈😂 My solution is to turn the setup completely off until load-shedding is announced. So the conclusion must be we have super powers lol

April 11, 20233 yr Hey guys, just installed a new Deye 5.6KVA inverter today my main (Newest Samsung TV, and my PC) both have this buzzing which I cannot stand either. Has anyone made any headway to finding a solution as yet?

April 14, 20233 yr Bought the Mecer Axpert 5.6K MKS. Over these Deye things and their unresolved issues that sound omitting from my appliances was destroying my brain as well as my soul. 2 days troubleshooting and a full rewire of the house, to no avail. Replaced it with the Mecer - noise gone.
February 25, 20242 yr I solved the noise problem with 3 120 mm silent pcfans The 12kw deye inverter has an internal fan that Are very noisy . this fan is starting at about 35 gr.c , to make the inverter silent is to keep it under 35.gr.c If you got a 3d printer i have uploadet the stl files to thingiverse https://www.thingiverse.com/thing:6125037
