First day solar production(12/5)

that seems pretty darn good. I have 11.8 kW system and yesterday did 19.3 kWh for the day. My panels are split east and west
Seems roughly right. I'm assuming you mean an 8.16 kW system. A very rough estimate on production is take the peak number and multiply by 4 or 5 to get an estimate of the *average* daily production, so 32 to 40 kWh/day. So you're probably going to up around 22 kWh for the today. But it is winter so production will be below average. The shape of the graph makes me think it's mostly a clear day. Lots and lots rounding and assuming but I believe roughly right.

What was your total production for the day?
For reference, I was testing my 23 panel 7.9 kWp AC system today for the first time in NorCal, and it generated 21.21 kWh according to Enphase's tracking tools and 19.8 kWh according to Tesla's software. But 2 of my panels aren't working.
All panels facing 135 azimuth with about 30 degree tilt.
Plus we had a lot of cloud-cover in the afternoon so my production fell off a cliff after about 1pm Pacific.

I think its a good day in L.A
23.2 kwh today. Grid was not used the entire day. My TOU peak rate is 4 to 9 pm. Since 4 pm, Powerwall is powering the house.

@mnsweeps, same solar system size as you. 3PWs, not sure your PW count, but we’re in SF Bay area. Yesterday started out nicely but clouds moved in. Here’s my comparison charts for then.
Today’s been foggy in the morning and overcast conditions predicted for rest of day, so not much sun getting through. Won’t replenish PWs today. Rest of week from Dark Skies says sunny. Expect to top off PWs by noon tomorrow and start charging my car then. PWs at 74% now.
November (pretty sunny month) was our first full month of using solar. For anyone looking to compare our system/area to yours, here’s our charts for November and so far for December.
I’m assuming the small percentage “To Grid” each day is a normal thing?

So today the 2 PWs charged up to 99% from solar and went back to STANDBY mode...and excess solar started getting fed to the grid. This is the expected behavior and really happy how its working.
My question is should the PWs stop charging at 99% or should it go all the way to 100%. I am assuming its intentional so PWs can recalibrate the numbers and keeps the 1% buffer for it?

Nevermind.... I will answer my own question ..looks like i was right in recalibration. Now after 10 mins it shows 100% View media item 122133
