New Solar/Powerwall Install - PW at 0%

Tesla installed our solar and Powerwalls on Tuesday and we are now waiting for SRP interconnect. They tested the system briefly but left the Powerwalls basically at 0%. Anyone else with a new installation have their Powerwalls left completely discharged? I know there is a buffer but I worry that sitting near the bottom is not good for the batteries?
 
Yes, my Powerwall was installed at the end of January and the roof wasn't installed until early March, system was commissioned end of March and not PTO'ed until end of April. My PW reported 14% (app, 18% web) the first time I could talk to it (late March), but since it loses >1%/day it had sat at 0% for a few weeks before I could finally turn the system on.
 
Turn it on and charge it up. They actually told me to do this after install but just be careful sending power back to the grid. Will throw a red flag. Keep setting on self powered.
I’m not sure this will work yet unfortunately. When they tested the system they had some bus bars installed in lieu of the missing power meters, but they pulled those before they left. So I imagine it might be an open circuit even if I flip the breakers to turn on the system?

I doubt it. Usually the system should be fully operational before they leave. I'm sure the breakers in the box are just flipped off and main throw is off. They will not come back to do more work. Next is just the inspections so the guy that comes doesn't actually do anything besides paperwork.

Try switching to Backup mode and see if the batteries will charge.

edit..... won't work if you dont have grid power

I think maybe the missing meters (yet to be installed by the utility) are in series with the breakers. I actually asked one of the installers if it was possible to disconnect from the grid and use the system prior to PTO but he said it wouldn’t work because the meters needed to be installed.
