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 derated
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
abnormality) occurs. “FAULT” will not light out until the fault
is eliminated. The light will blink slowly when an alarm
occurs. “FAULT” keeps being lighted up when an internal
fault occurs.
The buzzer will give alarms if a fault (involving power
grid abnormality) occurs.
