What you can do
- Check the last reading's date and time and the phone and building internet connection.
- Record messages visible without opening equipment and consult the system owner's manual.
- Give this information to the installer or service provider instead of diagnosing from a single app value.
How to tell whether it helped
After communication returns, check the reading's timestamp. Fresh but unexpected production data still needs installer assessment.
When to stop
Do not open the inverter, disconnect DC connectors or climb onto the roof.
