Transient/ Severity Description
Steady
Transient Normal Inverter is connected to REbus
and disconnecting from its grid
connection
Steady Normal Inverter is connected to the grid
Steady Normal Inverter is islanded / disconnected
from the grid
Steady Fault REbus is too high for the inverter
(Low) to operate safely
Steady Error General error state
Steady Error General error state/ inverter did
not enter a state of operation
Steady Error Inverter experienced a fault on
REbus and stopped moving
