102
AC voltage too high
Fronius · Symo Advanced Manual
Was bedeutet 102 ?
The inverter has detected that the AC voltage from the public grid is above permissible limits. As a safety measure, the inverter disconnects itself from the grid. It will resume feeding energy once grid conditions return to a safe range after a stipulated monitoring period.
Häufige Ursachen
- Public grid voltage instability or overvoltage condition
- Incorrect grid connection impedance causing localized voltage rise
