# Tesla Solar Production Limited alert: what it means and what to do

"Solar Production Limited" with the banner "Service Required - Fault Detected" means one of your inverters may not be producing solar because a fault was detected in your solar system. Tesla's instruction is to contact your installer to schedule a site visit.

## Common causes

- A fault detected on one of the solar inputs or inverters. Tesla's alert does not name the specific fault; a technician reads it from the system.
- Damage or a wiring problem in the solar array that the inverter has shut down to protect against.

## Safe steps to try

1. **Check the app for which inverter is affected** In the Tesla app, check whether solar production has dropped to zero or only partly, and note when the alert started.
2. **Do not touch the solar equipment** This alert requires service. Do not open the inverter, Powerwall or any rooftop equipment.
3. **Contact your installer** Tesla's guidance for this alert is to contact your installer to schedule a site visit. Share the alert text, the date it started and a screenshot of your production.

## When to call a professional

Call your installer or a qualified solar technician as soon as you see this alert. Until the fault is fixed, some or all of your solar production may be lost.

## Frequently asked questions

### Is my Powerwall still working?

The alert refers to solar production. Powerwall may continue to operate, but with less solar available to charge it. Check the app for any separate Powerwall alerts.

### Will the fault clear on its own?

Tesla lists this alert as Service Required, which means it needs a technician rather than a reset.
