PV Energy Reporting Seems Off

[Steve777]

I think I have captured the "smoking gun" of the app reported PV energy being off. Here's what I found:

Been fairly cloudy since I turned on the AIO, so hard to get accurate long term numbers, but today is brilliantly sunny with no clouds, so I monitored the PV input. This is with my old PV strings which were previously going into a Midnite Classic 150. About 2700W label power on the panels. (Note the strings have been rearranged to get the voltage up for the AIO).

In monitoring today, from ~10AM to 2PM, I am seeing consistent power output of around 2Kw.This is in the same ballpark as I used to get from these panels when they were attached to the Classic 150. That ~2Kw is very constant, varying +/-.2kw but always there the many times I check. So far good.

What is inconsistent is the reported KWH. Typically with the Classic these panels would have produced 6-8KWH on a day like today in the winter. The online app is showing 3KWH of PV production in the pie charts??? And if you look at the PV production graph down below, it shows ~2Kw from roughly 10:30 to 1:30. Roughly 3 hrs x 2Kw should be about 6KWH, no? Something seems wrong.

Either I misunderstand the KWHs the app is reporting, or something seems to be off here.

Anyone have an explanation?

If you attached screenshot or photo it isn't on here.
Seems like every shunt in every device says different things.
The Classic has always been pretty accurate . The Whizbang on the Classic SOC  is always pretty accurate too.
But my batteries reported SOC  can be close to the same but can also get way off .
I don't have that  Midnite AIO so can't comment.
Does it have more than one mppt input ? Do you have all your pv on one string on one mppt ?
Maybe it is not adding up all the different mppt inputs ?
Is it possible that is only reporting the pv input that makes it to the battery and the rest went to loads ?
