    Yes a software sensor, fortunately the growatt has seperate readouts (via api) for each string, so I have seperate them in my dashboard, I can total those readings up and get a fairly accurate sum of power.

    2kw instant power is the maximum I've seen across both arrays.

    I do seem to get shading when the sun first comes up due to its low angle and toward the end where it dips behind the horizon (we live in a bit of a valley).

    Here is mine from yesterday.

    It clouded over in the afternoon, otherwise it would have been more symmetrical.

    One thing I notice is that in the morning and evening the panels at the top generate more than those at the bottom as the ones at the bottom come out/in to the shade. Without Solaredge I presume they would generate according to the lower panels until they all in the sun. Not sure it will affect the total generation much but may influence the shape of the tails.
