Tesla Powerwall › Problems
Powerwall system won't export solar, or the export limit drops
The system never sends solar to the grid, solar production looks capped, or the export limit has dropped. This page covers what the app warning means, what to check first, and the causes behind it.
Error codes that go with this problem
| Code | What it means |
|---|---|
| no permission to export | A warning on the app's energy screen that permission to export is not active. |
What to check first
- In the Tesla app, open Settings, Powerwall, Advanced Options and look at Permission to Export. Once the utility has granted Permission to Operate, switch it from No to Yes.
- Compare the export limit set on the system now with the limit it had before.
- If the Charge on Solar option for a Tesla vehicle disappears after switching Permission to Export, turn it on, clear the export warning, re-pair the vehicle, then turn it off again.
- If the export limit has dropped to 4 kW, or drops back to 4 kW after being restored, contact Tesla support.
