Buzzing since solar was installed

oldskoo1

Hi all

This buzzing was noticed just after i had my solar pv installed.

I initially thought it was the iBoost. I have since realised even with the iBoost off i am getting some buzzing.

It is creating an issue with certain electronics, most obvious is my iMac which also buzzes, quite annoying whilst working on it.

I don't know how to fault find, i can only trace it back to the meter box outside. Inside the meter box, next to the meter i have a mini RCD which the solar is connected to. This then feeds into a splitter box which takes a cable from the main electrical entry point from the street into my house.

I could be wrong but the buzzing seems louder on the meter instead of the RCD / breaker.

But as mentioned, this only started since solar was installed.

Any ideas?

thanks

It is very unlikely, but when I used inverters 40 years ago they used to produce a square wave rather than a sine wave. The square wave inverters caused buzzing in many electrical items. Could the inverter be producing a waveform that is less than puristically sinusoidal?

Are all the electrical connections tight? I'd be getting the installers sparky back asap to prove all his electrics?

Is the buzzing only when the inverter is doing its thang?
Does it happen at night?
If the former then, again, I'd be on to the installers and get them to check the box is good and if necessary get the manufacturer to investigate?
If it's all the time then to me that points to something within the changed electrics, so back to the installers and their sparky again?

I would be surprised if any inverter was able to produce a perfect sinusoidal wave.

Reading the thread title I thought you meant buzzing with excitement, haha.
I am, especially after generating 16.45kWh today considering how cloudy the morning was.
Hope you get your buzzing sorted.
