The reason is given in the manual…
Err 59 - ACIN1 relay test fault
Automatic checking of the disconnect means failure. This usually indicates a broken relay (sticky contact) in the AC input stage.
Try to restart the Multi RS Solar by switching it off and then on again at the rocker switch. If the error persists then a relay is likely to be faulty.
The end action is the same. If it does not clear. Return the unit go through the due process.
