After getting my solar clamps installed a month or so back, I notices a weird, but consistent pattern in the usage graph. I was able to get it resolved, but it came back (and stayed) today when we opened the panel for the inspection.
When zoomed out, the drop is consistent no matter the load as seen here:
And zoomed all the way in (left image), it’s a minor drop consistently taking place every 2 second or so.
I tried to pull the unit out and reseat all the cables, but it’s still there. Solar is still not active (no production meter yet), so curious if anyone else has seen something similar.
