How is your production? What time period is that ouput data from? Does that picture represent your three planes? How was it in September?
There is an online tool available at pvwatts.org that might give you a way to model a typical system in your location to benchmark against your historical output.
I have a 8.16 kW PV, 2 PW system and a SE7600H-US Inverter installed Sep. 2020. It looks like I have only 1 string of 24 panels. I have panels on 3 different roof planes (16, 5 and 3 panels). Is this okay?
From what you said and showed I don't have any concerns. All strings are parallel within a SE inverter anyway. Its the optimizers that do the work, rather than individual MPPT trackers.
Pretty sure Tesla is using double optimizers these days, so longer strings are possible. If you aren't noticing a production issue, don't worry.
Shorter strings are worse than long ones as then you can lose target voltage.
My SE app shows all 33 panels on one string. I had a tech out for a different issue and asked him about it. He said that in fact there are three physical strings but for whatever reason it was mapped as one string when commissioned. All panels produce well so I am guessing it’s fine.
