Error: 411DSP communicates with M3 abnormal

Name in the manufacturer's documentation (user manual): DSP communicates with M3 abnormal[1]

In plain words (editorial)

The DSP and M3 processors inside the inverter cannot communicate properly. The manual says to restart; if it stays, the DSP and M3 firmware is updated or a board is replaced.

When to call a service technician: Firmware updates and board replacement are for the installer or Growatt.
