Getting production above rating.... 7.3kw out of a 6.6kw system

second time that i've seen this.... producing as much as 7.3KW point in time from a 6.6KW system (20 x 330w panels) per the Tesla app.

I have a 7.6kw inverter. screeshot attached. My Powerwalls were fully charged at the time. i'm not complaining. it just seems inexplicable to me. FYI, it was about 40 degrees Fahrenheit outside at the time in both of the cases i've observed a reading this high.

It's the low temperature. The reverse will happen when they get hot. The panels are rated based on a standard test temperature of 77 F.

The other factor also is the "cloud edge effect". When there are clouds around, I have seen output over 7 kW from my 6.3 kW system.
