Commissioning was basically a test of functions. I had the Tesla app open on my phone so I could follow along with the tests. The commissioning was early in the morning so the system was not yet producing full power.
With the grid turned off, solar was powering the house.
Solar to the house
When house usage was lower than production, solar powered both the house and charged the battery.
Turning off solar and grid powered the house from the battery.
Battery to the house
And when the grid was turned back on, the house was powered by the grid while solar charged the battery.

Before the installer left he set the battery charge to 50% which meant the battery would take all the solar power until it is 50% charged and then solar will feed power to the house and excess to the battery. He said that is typical.
The inverter displays the amount of power it is converting to AC. So I took a photo of it too.

The saddest part was turning off the solar system to await inspection and the power company thay has to come out and install the grid feed meter before the system can be used.
