Fronius · Primo GEN24 Operating Instructions

What does 415 mean?

This code indicates that a safety cut-out mechanism, either via an installed option card or the RECERBO system, has been triggered. This critical safety event causes the inverter to immediately stop feeding energy into the grid.

Common Causes

  • Activation of an external safety mechanism connected to an option card.
  • Fault condition detected by the RECERBO system (e.g., ground fault, overcurrent).
  • External emergency stop or grid protection device trip.
