4.2 Operation State
Table 4.1 describes the meaning of LED indicators (i.e. it indicates the inverter’s
operational state).
“POWER” will light up to indicate that the system is energized and
under DSP control.
“RUN” will light up when the inverter detects that the grid connection
conditions meet the requirements and power is fed into the grid. “RUN”
will blink if the grid is in de-rated running state during the period of
feeding power into the grid.
“GRID” will light up when the grid is normal during the operation of the
inverter. Otherwise, “GRID” will blink until the grid restores to normal.
“FAULT” will blink quickly as a fault (except grid fault) occurs. “FAULT”
will not turn off until the fault is eliminated. The light will blink slowly
when an alarm occurs. “FAULT” remains illuminated when an internal
fault occurs. The buzzer will give an alarm if a fault (involving power
grid fault) occurs.
