AC voltage too high
Fronius · Primo GEN24
¿Qué significa 102 ?
The AC grid voltage at the inverter's connection point is too high, exceeding the permitted limits for the Fronius Primo GEN24 208-240 inverter. This condition can lead to the inverter disconnecting from the grid to protect itself and the system.
Causas comunes
- The grid voltage is too high.
- Impedance in the AC connection cable is too high (cable too long, cross-section too small).
- The grid impedance is too high (local grid problem).
Pasos de reparación & Lista de verificación

- 1
Verify the AC grid voltage at the inverter's connection point using a multimeter and compare it with the Fronius Primo GEN24 208-240 inverter's specified operating limits.
- 2
Check the length and cross-section of the AC connection cable; ensure it is adequately sized for the distance and current to minimize impedance.
- 3
Inspect all AC connections for proper termination and secure contact.
- 4
Contact the grid operator to report excessively high grid voltage or high grid impedance issues in the local network.
- 5
If applicable, check inverter settings related to grid voltage limits to ensure they comply with local grid codes.
