4.2 Operation State
“POWER”
LED indicates that the system is energized and under DSP
control when “POWER” lights up.
“RUN”
LED will illuminate when the inverter detects that the grid connection
conditions meet the requirements and power is being fed into the grid. The
“RUN” LED will blink if the grid is in a de-rated running state while feeding
power into the grid.
“GRID”
LED will illuminate when the grid is normal during inverter operation.
Otherwise, the
“GRID” LED will continue to blink until the grid restores to
normal.
“FAULT”
LED will blink quickly as a fault (except grid fault) occurs. The
“FAULT” LED will stay illuminated until the fault is eliminated. The LED will
blink slowly when an alarm occurs. The
“FAULT” LED remains illuminated
when an internal fault occurs.
The buzzer will sound if a fault (involving power grid fault) occurs.
