4.2 Operation State
Table 4.1 indicates the definitions of LED, i.e. indicates the information of the
inverter’s operation state. It indicates that the system is energized and under DSP
control when “POWER” lights up.
“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.
4.3 Interface Types
Users can perform the corresponding operations with the 4 function keys
according to the indications of the LCD.
