hard reset on PC requires holding down the power button
Our TEG is outside and accessible. However, we'll be home tomorrow and I'll work on the system then.
Usually reset switches require more than a single press and release - may have to hold down for multiple seconds.
Our system isn't hung - it's running and operating. So a software reset should work.
Or, if there was a way to force the TEG to reinstall the last software update - that would also do the equivalent of a reset.
That sucks.....The installer tech just left after spending hours on the phone with the Tesla Energy support - who was also talking with Tesla engineering...
Tesla has not seen a system failure like ours before...
All 4 PowerWalls refuse to power up. According to Tesla's data before the TEG lost connection, the PowerWalls each have at least 75% power - and based on the Power Flow charts for the day of failure, I suspect it's more likely 100%. According to Tesla, we'll get a very slow vampire drain - but the PowerWalls will not discharge unless the TEG sends the command - and because the connection to the TEG is down, the PowerWalls should not discharge. And based on the grid power usage since the failure, I don't see any periods when the PowerWalls were providing power. So we're pretty confident the 4 PowerWalls have plenty of power - it's just that they won't power up because they are not able to communicate with the TEG.
The technician tried connecting only one PowerWall at a time - and ran a new data cable - and nothing worked.
He checked the power on the data cable coming out of the TEG and instead of 12V, all that's coming out is 1.2V - not enough to communicate with the PWs.
So they're ordering a replacement motherboard for the TEG - which will take several weeks. Until then, we'll get solar power - but if there's a power outage, we'll likely lose power....
While on the phone with Tesla support, I mentioned the lack of remote reset capability - which would be very convenient. We discussed the possibility of forcing the TEG to re-install the latest firmware, which would also result in a reboot/reset - which could be done from the TEG installer web interface. The support person is going to send the request for a remote reset or firmware reinstall back to engineering for consideration.
I never knew this screen existed until I saw this post.Also, once they DO get around to installing the new motherboard, you will need to have them connect it to your Tesla username so you can see it on your app. That took me less than 3 minutes on the phone with support. Now, 7 months later, I STILL have the old on on my phone too. I have called support 3 times to remove it, but they have never gotten off . It just shows 'unavailable'.

We seem to be in the same boat. 0.05V on the CANbus. Powerwalls completely dark, and no amount of switch or breaker flipping seems to get them online.Well...
When I came home - all 4 PowerWalls were completely dark.
Tried turning them off and then on - no change.
Tried pressing the reset button on the TEG - no change.
Threw the breakers for the PowerWalls, solar panels and the grid power and waited 10 minutes - no change.
We're getting power from the solar panels - which is being routed to the house and back to the grid.
But the PowerWalls continue to be completely dark. The Tesla app reports 0% charge and doesn't show any power going to/from the PowerWalls. The TEG web interface shows the PowerWalls at 0% with a ? where it would normally show 4 (for the # of PWs). Stopped the system and ran the diagnostics - which indicates the CAN bus is not working to the PowerWalls.
Have spent about 2 hours on hold with Tesla to get PW support - and was put into a callback queue (for at least another 49 minute wait).
Reached out to our solar/PW installer - and they're checking if they have a tech in the area.
Our system has been running without any problems since it was installed in December 2019.
Anyone else see this issue?
