Battery Current

¿Qué significa 603 ?

This status code indicates that the battery current is too high during either charging or discharging, as detected by the Fronius Primo GEN24 208-240 inverter. This can be caused by an overcurrent condition, a short circuit in the battery wiring, or an internal fault within the battery system, potentially leading to damage.

• An overcurrent condition during battery charging or discharging.
• A short circuit in the DC wiring connecting the battery to the inverter.
• An internal fault within the battery system (e.g., BMS issue) causing abnormal current flow.

1. 1

   Monitor the battery current during operation via the inverter's display or monitoring system to identify when the overcurrent occurs.

2. 2

   Inspect the battery wiring between the inverter and battery for any signs of short circuits or damaged insulation.

3. 3

   Check the battery system's internal fault indicators or display for specific current-related warnings.

4. 4

   De-energize the inverter and battery system, wait for 5 minutes, then re-energize. If the message persists, the battery system may require service.
