Description
Causes
Initializat-
ion
Waiting
Initial PV voltage is between minimum DC
input voltage and the start-up DC input
voltage of the inverter.
Checking
The inverter is checking the feed-in
conditions after the initial PV voltage
exceeds the start-up DC input voltage of
the inverter.
Reconnect
The inverter is checking feed-in
conditions after the occured fault has
been solved.
Normal
Normal
The inverter is feeding power into grid
normally.
