Beginning with Powerwall software version 24.12, Powerwall 3 will enter a Sleep state when the following are true for more than 10
minutes:
The Powerwall 3 Enable switch is ON
In Tesla One, the system is OFF (stopped)
The Sleep state ensures Powerwall 3 does not drain its State of Energy (SOE) to 0%, at which point it cannot be
recovered.
Every two hours, Powerwall 3 will automatically wake:
If the system has been
started in Tesla One, Powerwall 3 will remain awake and
will resume normal operation
Otherwise, Powerwall 3 will return to the Sleep state after 10 minutes
Note
Powerwall 3 may enter the Sleep state during installation; the only exception to this
rule is when the Powerwall software is updating - in this case Powerwall 3 will not go to sleep. See Waking Powerwall 3 from Sleep State to manually wake a Powerwall 3 that has gone to sleep during installation.
Note
If the installer attempts to
exit Tesla One with the Powerwall 3 switch ON and the system
OFF, an alert will remind the installer to either start the system or turn the Powerwall 3 switch OFF.
Confirming
Powerwall 3 is in Sleep State
For all Powerwall 3 systems, the logo LED is the
primary method of confirming Powerwall 3 is in the Sleep state:
LED State
System Status
White flashing (1s)
Powerwall 3 has entered
the 10 minute waiting period, and the Powerwall 3 switch
should be turned OFF or the system should be started
OFF
Powerwall 3 is in the
Sleep state
Note
For Powerwall 3 systems installed with
Backup Gateway 2, the TACO LEDs will remain ON even though Powerwall 3 is asleep. This is
because the TACO receives 12V power from both Powerwall 3 and Backup Gateway 2.
Rather than relying on the TACO LEDs, look to the Powerwall 3 logo LED to confirm
Sleep state.
Placing
Powerwall 3 in a Stable State
The Powerwall 3 Sleep state is intended to
protect Powerwall 3 from draining its SOE to 0%.
Rather than leaving Powerwall 3 in this state, do one of the
following to leave Powerwall 3 in a stable state:
Option 1
(Preferred)
In Tesla One, select Start
System. This is the preferred action because it keeps
the system online and connected to the internet for monitoring.
Note
Confirm the Powerwall 3 LED turns solid white to indicate Powerwall 3 is in a stable state.
Option
2
Turn the Powerwall 3 switch OFF. This
action is acceptable when it is not possible to connect Powerwall 3 to AC power
(new construction, solar installation is actively in progress,
etc.)
Note
If the sleeping Powerwall 3 is a Follower unit rather than a Leader, ensure the inter-Powerwall
Ethernet cable is connected.
Waking Powerwall 3 from Sleep State
To manually wake Powerwall 3, turn the Powerwall 3 Enable switch OFF, wait three
seconds, then turn ON. Powerwall 3 will boot up in about 90
seconds, and the LED will turn light red.
Once the red LED appears, turn the Powerwall 3 Enable switch OFF, wait three seconds, then turn ON.
Note
As noted above, Powerwall 3 will automatically wake
every two hours; if the system has been started, it will boot up and return to
normal operation. This automatic wake-up cycle ensures Powerwall 3 can automatically recover
from 0% SOE conditions, such as a long-duration grid outage.
