What do the LED lights mean?

Once your Powerwall restarts, here's what the LED indicator light tells you:

• 🟢 Solid White — Everything is working normally.
• ⚪ Flashing White — Powerwall is idle (no charging or discharging activity).
• ⚫ No Light — Powerwall is off or in sleep mode.
• 🔴 Flashing Red — There is a fault that needs attention. Please contact us if you see this.

Note about Expansion Units: If you have Powerwall 3 Expansion units, they do not have their own on/off switch. They will automatically shut down when the main Powerwall 3 is turned off and restart when it comes back on.
