In 2020 I started building an offgrid house, first thing I bought was a Victron Quattro 10kva and Bluenova 16kv battery.
Since day one when testing the Quattro it made a click noise like relay opening and closing and it affected the output voltage.
The strange thing is it only does this with my bean to cup coffee machine and a cheap inexpensive hairdryer.
The Quattro was send back with the pink hairdryer. The supplier tested the Quattro and found nothing wrong. They said that it will work normally when complete installation is done.
Forward 2 years and eventually the system is installed. And the same is happening.
At this stage I'm not sure what to do, as in South Africa we do not have direct access to the Victron importer.
