Internal fault (e.g. surge protection device)

What does 713 mean?

The Fronius Primo GEN24 208-240 inverter has detected an internal fault related to its surge protection device (SPD). This indicates that the SPD may have failed, potentially due to a voltage surge, compromising the inverter's protection against transient overvoltages.

• Internal fault (e.g. surge protection device).
• SPD has tripped or is damaged from a surge event.

Click steps to track your progress.

1. 1

   Inspect the surge protection device (SPD) within the Fronius Primo GEN24 208-240 inverter's connection area (if visible and accessible by qualified personnel) for any fault indicators or tripped modules.

2. 2

   Perform a full power cycle of the inverter by cycling both AC and DC disconnects, waiting, and then reapplying power.

3. 3

   Check for any signs of recent electrical surges or lightning strikes in the vicinity that could have caused the SPD to activate or fail.

4. 4

   If the SPD has modular cartridges, verify they are correctly seated or check for indicators that they require replacement.

5. 5

   If the fault persists and the SPD appears damaged or faulty, contact Fronius service for inspection and potential replacement of the SPD.
