My SE monitoring account page says Lifetime is 2.07 MWh when in reality it's 640 KWh. Does this mean the inverter was previously installed or is that how much power they pushed through it to test it?
SE Inverter Odometer shows 2 MWh

Mine is pretty accurate. Is it possible that you consumed 1.360 MWhrs during its lifetime, creating a net 640 kWhrs?
How did you come up with 640kWhs? What period of time?
I am pretty sure the lifetime statistic comes from the cloud. What I mean is it is not in the inverter but in the account. I had a situation where my SE inverter was operating for about 14 months before the installer set up a user account and none of the previous history was accumulated.

I think I figured it out. The 640 is what I've produced since I got portal access turned on in late December. Apparently the Lifetime includes all production before that even though I can't see it in the portal.

You must have a big system to produce 640 kWhrs in a winter month. At that rate, you will love June.
Not that big. 8.16 kw.
The 640 kwh is 26 days of production with 10 days of that overcast. It would have bee 930 something kwh if it had been sunny every day.
650 kwh in December according to the Tesla app with 12 days of partial overcast.
So then it occurred to me that Lifetime solar production would be on the Telsa app. So I just checked that but it says 1480 kwh. But if I visit each month in the Tesla app and add up the solar production, it comes out to 1918 kwh which is not that far off from what SE says. So why the heck does Tesla say 1480 under lifetime when it's own data adds up to 1918?

You must have absolutely ideal exposure - I’m at your latitude and produce about 400kwh in Dec/Jan with a 7.5kw system.
Yes. No shading. Not due south but south/south west at azimuth 205. It turns out to be even better than 180 because it's more optimal for the new late afternoon peak NEM. Although that said, my numbers have been WAY higher than what pvwatts estimates plugging all the system values in. Yesterday was 37.8 (no overcast) and that was with a mid day inverter shutdown because I needed to install an Emporia Vue2 on the main service panel and it required power from the grid to be flowing to the house so I gave up about 0.4 kwh.
