Powerwall 3 Rapid Shutdown (RSD) Initiated
Symptoms
On the landing page, the following alert appears under the Powerwall 3: "Rapid Shutdown Initiated. Check AC breaker and low-voltage rapid shutdown circuit".
Warning
Only an Electrically Qualified Person is to perform these
troubleshooting steps.
Warning
This procedure includes steps to measure voltage across terminals
with breakers closed, meaning conductors are under load. Never unplug conductors
that are under load.
Steps to Troubleshoot
Note
It takes approximately 30 seconds to move out of the RSD triggered state; allow at
least 30 seconds after each troubleshooting step to see if the alert has been
cleared.
- Ensure the Enable switch is ON.
- Ensure the Rapid Shutdown (RSD)
jumper is in place for each Powerwall 3 (remove System Shutdown
Switch if present and reinstall RSD jumper to simplify troubleshooting).

- If there are multiple Powerwall 3 units installed, perform
the following steps to determine which unit is triggering RSD:

- Using a multimeter, measure the voltage between the RSD IN pin and a GND pin. The value should be approximately 12V.
- If the voltage measurement is 0, this unit is triggering RSD.
- For the unit triggering RSD:
- Remove the RSD jumper and
use the multimeter to measure the voltage across the two RSD pins. The
value should be approximately 12V; if it reads 12V, reinsert the RSD
jumper and wait 30 seconds to see if the alert is cleared.NoteIf the value is oscillating between 0V and 12V every second, please contact Install Hotline.
- Confirm the System Shutdown Switch was wired to the correct terminals in the RSD connector.
- Remove the RSD jumper and
use the multimeter to measure the voltage across the two RSD pins. The
value should be approximately 12V; if it reads 12V, reinsert the RSD
jumper and wait 30 seconds to see if the alert is cleared.
