Overvoltage on DC side (Battery)

¿Qué significa 507 ?

The Fronius Primo GEN24 208-240 inverter has detected an excessively high voltage from the connected battery system on the DC side, exceeding its maximum input/output voltage rating. This could indicate a battery management system (BMS) fault or an incompatible battery.

• Overvoltage on the DC side (battery).
• Faulty battery or battery management system (BMS).
• Incorrect battery connected to the inverter.

1. 1

   Disconnect the battery using the DC disconnector and measure the battery voltage at its terminals.

2. 2

   Compare the measured battery voltage with the nominal and maximum voltage specifications for both the battery and the Fronius Primo GEN24 208-240 inverter.

3. 3

   Consult the battery manufacturer's manual for any specific fault codes or diagnostics indicated by the battery system itself.

4. 4

   Verify that the connected battery system is compatible with the Fronius Primo GEN24 208-240 inverter model, checking both voltage and communication protocols.

5. 5

   If possible, perform a controlled shutdown and restart of the battery system. If the issue persists, the battery or its BMS may be faulty; contact the battery supplier or Fronius service.
