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 start-up PV voltage
exceeds the initial DC input voltage of the
inverter and that both the grid voltage
and frequency are normal .
Reconnect
The inverter is checking feed-in
conditions after the last fault has been
solved.
Normal
Normal
The inverter is feeding energy into grid
normally.
