Green LED:
The green LED starts to light up once the photovoltaic modules voltage is more than
125 V. The green LED indicates that the inverter is active and working normally. If
this LED does not light up, the inverter can not supply power to the grid. In normal,
this LED begins to light up in the morning when the sunshine intensity is enough
and goes out when it gets dark.
Red LED:
The red LED indicates that the inverter has stopped supplying power to the grid
because of a fault, and the exact fault information will display on the LCD at the
same time. The faults as follows in the table will active the red LED.
Yellow LED:
The yellow LED lights up during the inverter communicating with other devices
including PMU and PC and goes out after the communication finished.

Green
Normal
The inverter is operating
normally.
Red
Fault including: Output relay failure,
EEPROM problem, SCI failure, Output
AC sensor abnormal, GFCI detection
abnormal, Isolation failure, GFCI
failure, Fac Fault, Vac Fault, No
Utility, Input voltage too high, Output
DC injection too high, Fan abnormal,
Temperature abnormal, and Consistent
failure.
The inverter has a fault, and it
stops feeding. According to the
content which displays on the
LCD, look over the FAQ part to
resolve. If it doesn’t do, contact
your local service. On
elimination of the fault, the
inverter resume and the green
light on.
Yellow
During communicating
The inverter is communicating
with other devices including
PMU and PC.
