“RUN” will light up when the inverter detects that the grid connection
conditions meet the requirements and power is fed in

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.
