1. 1

   Perform a full power cycle of the Fronius Primo GEN24 208-240 inverter by disconnecting both AC and DC power, waiting, and then reapplying power.

2. 2

   Verify the DC connections between the inverter and the battery system are secure, correctly wired, and free from damage.

3. 3

   Check the battery system's own status or fault indicators; ensure the battery is operational and not reporting its own internal faults.

4. 4

   Review the inverter's event log for any preceding fault codes related to battery communication, voltage, or current.

5. 5

   If the fault persists after power cycling and external checks, this indicates a failure in the inverter's internal battery power conversion hardware; contact Fronius service.
