AC voltage too high

Was bedeutet 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.

• 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).

1. 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. 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. 3

   Inspect all AC connections for proper termination and secure contact.

4. 4

   Contact the grid operator to report excessively high grid voltage or high grid impedance issues in the local network.

5. 5

   If applicable, check inverter settings related to grid voltage limits to ensure they comply with local grid codes.
