I had my GivEnergy Hybrid 8kW Inverter Gen 3 installed a few months ago, it’s right next to my dining table as it’s in my utility room. From the moment of commissioning, it’s emitted a piercing high-pitched whine. I asked my installer to seek support from GivEnergy at the time, they slowly asked some delaying questions then disappeared.
Anyway this is very painful for me every day, is there a way to change the switching frequency of the inverter so that it doesn’t sound so painful?
My parents have an AC-coupled All-in-One, it doesn’t make sound like this, so the thought hadn’t occurred to me when picking GivEnergy that their products could hurt me.
I have solar panels connected to the inverter too. I haven’t noticed whether different modes or power draws of the inverter result in any change in the sound.
