I have a newly commissioned 8.19 kWh PV + 2 Powerwall system. The hardware itself was installed 7/16. It took a while for the building inspector to sign off on the install (he found chipped roof tiles that Tesla had to replace). PG&E sent the PTO about 8 days after Tesla submitted the interconnect agreement. That happened a couple of days ago.
Before the PTO, I spent time playing with the system. I set up a Grafana dashboard-based monitoring system to watch the operation of the system (thanks to Jason @ rhodesman/teslaPowerDash for the great template to work from).
The first thing I noticed is that my dashboard is showing 25.4kW for the pack's total energy. Looking at the JSON returned from Tesla's API:
curl --request GET --header 'Authorization: Bearer XXX' https://owner-api.teslamotors.com/api/1/products | jq .response[2].total_pack_energy
I see "25376". The spec for each powerwall is 13.5kW usable, so the pair should be ~27kW. I would expect the returned value, especially on a brand new install, to be a lot closer to 27000. What values are others seeing on their systems?

Note: I have 2 cars appearing first in the returned array, hence the index 2 for the energy site
