Hello, I have a simple system, connecting a Multi RS Solar 48 v 6000 to 6 solar panels that are 415 w each and 218 v and 4 batteries of 12 v and 260 Ah. My panel system a grid of 2 panel connected in series this done 3 time, and all of those are connected in parallel. My batteries are all connected in series to have a 48 v batterie of 260 Ah.
I have just received my Multi RS solar and I have a weird looking power signal. it keeps on oscillating from 0 w up to 60 w depending how sunny is the day.
here is what it can look like.
if someone as an idea of what is wrong I would appreciate a lead.
