Grid fault

SMA · Sunny Boy Solar Inverter

Was bedeutet 101 ?

The grid voltage or grid impedance at the inverter's connection point is too high, leading to the inverter disconnecting from the utility grid. This action prevents damage to the inverter and helps maintain overall power quality.

Häufige Ursachen

  • Grid voltage at the connection point is permanently too high.
  • Grid impedance at the connection point is too high.
  • Local grid conditions causing voltage to be outside the permissible range.

  1. 1

    Check whether the grid voltage at the connection point of the inverter is permanently within the permissible range.

  2. 2

    If grid voltage is outside permissible range due to local grid conditions, contact the grid operator for adjustment or change of operating limits.
