Multiplus II grid settings for Reactive power.
Where can I find information on these settings.
I have the idea that the multiplus is trying to bring the cos phi to 1 and that that causes some zooming noise. Is my reasoning correct on this. If so can I disable the multiplus in trying to compensate for this ?
The sounds the multis make are the sounds they make, there isn't much you can tune to change it, short of using it less or being off-grid. It will do what it does irrespective of what you set the grid to.
There are many topics on this forum with advice to improve it, and if you have a recent one, fans are much quieter but the transformer is still a transformer and will hum like transformers do, more so when synchronising with the grid.
Strange thing is, is that the hum looks louder when the multiplus shouldn't have nothing to do. I have it in a setup just to compensate for my grid use (in parallel) and at night it shouldn't do nothing and it look the hum is than louder.
