Regular (10min) dips in solar meter

Clear day- no high level cloud so perfect solar day. I have 2 Fronius solar inverters. One connected to each panel. I am looking at the meter on sense and I see there brief double dips so far throughout the day. They are occurring every 10 min (pretty well to the second). Would this be a sense blip? I have attached a screen capture of the 1st sense I am also seeing it on my other inverter (2nd image)

I plan to ask fronius too

Here is the 1 hr view. The upper meter is solar and is maxed out at 6KW. The dips are like clockwork- every 10 min
