    So, while I am waiting for PTO, I am doing a bit of testing. During today's test period, my Tesla app says I created 7.8 kWh but my Sense app says I made 31kWH?? Does Tesla have something set up wrong?

    how big is your system?
    In any case, the tesla number seems very low. Probably another case of CTs installed incorrectly. Many people have reported that issue

    I have a 12.24 (36 panels). I looked at the CT's and they look like they are installed correctly. They are on the mains, pointing towards the source.

    I have a slightly smaller system (11kW) and produced 43kWh today. What does your solar production curve look like in the app?

    It is pretty choppy and drops quickly. I only ran it for 6 hours or so to test. Sense show a max of 10.9 (it may started clipping there) but it was nice and constant. Nice sunny day here. I don't expect much more than 11 as my two Tesla inverters have a combined max of 11.4.

    were there clouds to explain the drops? Otherwise, it has to be CTs. Depending on how they are installed wrong, they could report very choppy production and usage.

    you need to show us the tesla app, with all the sources turned on (all 4 bubbles, home, solar, grid, and if you have them powerwalls).

    If you dont have powerwalls you may not have that level of monitoring.

    Is it possible that your sense app is showing you "total" kWh, while whatever you are looking at from tesla is "net" (as your home is consuming some load?)

    If I had to guess, I would say that you could be looking at tesla app reporting what you pushed back to the grid, while sense is showing what the total production was (not counting home consumption).

    As you can see it is just pretty low.

    yes, looks low. My peak with 11.8 kW system was 6.8 kW and my config is East/West panels
    What is your panel configuration?

    I still think it is the CTs. Maybe only half your system is being reported?

    I was thinking about the half thing. I know both inverters are working. Sense seems to be working, I will just wait until PTO and hit up Tesla.. I have 24 panels true south and 12 east with no obstructions or shadows..
