If the Discovery process fails, verify the following:
- System configuration is complete
- Cloud Connect Advanced (CCA)/Cloud Connect/MMU has an active Internet connection and has downloaded the system configuration files
- TAPs/Gateways are properly wired (check polarity at both ends and termination resistor). If using Cat5 cable, see our wiring recommendations.
- There is enough time for Discovery to finish before sunset
If these steps do not prove to be effective, try the following:
- For one of the panels, copy the optimizer serial number and delete it
- Click "Save"
- Add back the optimizer serial number
- Click "Save"
- Re-start discovery
This causes the configuration file to be resent to the MMU/CC/CCA.
If Discovery still fails after verifying each of these, take note of the Discovery error code and contact Tigo Support at 844.805.8550 or 408.402.0802 ext.2 (outside USA) or email support@tigoenergy.com to open a ticket.
