F48AC lower frequency

Name in the manufacturer's documentation (user manual): AC lower frequency[1]

In plain words (editorial)

The grid frequency is too low. The manual says to check that it is within the specification and that the AC cables are firmly and correctly connected.

When to call a service technician: If it does not return to normal, contact your installer or Deye support.
