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
