spotty drops in solar generation


Hi


I just upgraded my solar configuration:

  • used to have a single string of a series of 10 panels
  • Moved to two strings one with roughly 600w and the second with about the same

Since then the production graph shows this strange curve that I never experienced before - looks like every now and then there is a negative spike of about the half (although timing and amount seems not have a connection):



Anybody have any idea of what it could be? could it be that the isolator diodes used between the two strings are not properly working?


THANKS
