F13Grid_Mode_changed

Name in the manufacturer's documentation (fault list): Grid_Mode_changed[1]

In plain words (editorial)

F13 means the grid mode changed – for example after changing the grid type or frequency, after setting the battery mode to “No battery”, or on some old firmware after changing the work mode. The manual says it generally disappears automatically; if not, turn off the DC and AC switches, wait one minute and switch them on again.

When to call a service technician: If the inverter does not return to normal, contact the installer.
