DC input voltage MPPT2 too high

Hva betyr 313 ?

This code indicates that the DC input voltage from the PV string connected to Maximum Power Point Tracker 2 (MPPT 2) is too high. This triggers a short-term interruption in energy feeding, and the inverter will attempt to resume its startup routine.

• PV string connected to MPPT2 has an open-circuit voltage (Voc) that exceeds the inverter's maximum input voltage.
• Faulty PV modules in the string leading to excessive voltage.
• Incorrect string configuration or number of modules for MPPT2.

1. 1

   If the status code is displayed continuously, notify a Fronius-trained service engineer.

2. 2

   Verify the open-circuit voltage (Voc) of the PV string connected to MPPT2 and ensure it is within the inverter's specified limits.

3. 3

   Reconfigure or modify the PV string connected to MPPT2 if its voltage exceeds the inverter's rating.
