Sound from solar panels

When I turn on my battery beakers, the entire wall box where all the wires are located, creaks just as though I’d turned on water pressure to plumbing.

Haven’t quite figured out why or whether to worry about it.
Can you show a picture of the setup?

inrush. Do you have a precharge circuit?

No. The SOK rack directly wired (through a fuse) to the Victron stuff.

Do I need to do it differently? It’s been a few months since I set it up and I don’t recall whether I cut a corner.

Not sure! If it isn't broken, probably shouldn't fix it until it becomes broken!
 
Wonder if its your connections expanding as they start moving current? Double checked all of your bolts for snugness?

Im probably mostly wrong but,... Any current traveling thru a wire induces a magnetic field. If Pos and Neg are far enough away from each other, the fields do some funny things. Given the start up amps, I do not find this surprising, but, I would be concerned enough to look further into it if I were you.
