What to do if SMA SUNNY BOY 3.0-US shows 'Grid fault'?
- E
  elijah56Nov 22, 2025
  If your SMA Inverter displays a 'Grid fault' message, it could be due to several reasons: * The grid voltage or grid impedance at the connection point of the inverter is too high. * The utility grid has been disconnected, the AC cable is damaged, or the grid voltage at the connection point of the inverter is too low. * The ten-minute average value of the grid voltage is no longer within the permissible range. * A stand-alone grid or a very large change in the power frequency was detected. * The power frequency is not within the permissible range. * The inverter has detected an excessively high proportion of direct current in the grid current. To resolve this, ensure the circuit breaker is switched on, the AC cable is not damaged and correctly connected, and the correct c...
