I have a Growatt on-grid 15kw inverter that's not producing smooth graphs with many small dips over the day. I thought this was normal until I saw a friend's graphs and they were rather smooth.
This is on a normal clear day with no shade/clouds etc. It's the same thing daily.
Please see the screenshot. I have noticed similar fluctations on MPPT voltage too that keeps varying.
Is this normal and what could be causing it?
