8.2 LED indicators
The three LED indicators from top to bottom are:
1. SOLAR power indicator
When the inverter is in the standby self-checking state, the
white light flashes. Under normal grid-connected working state,
the light is always on. In “Fault” mode, the light is off.
2. COM communication indicator
When the inverter communicates with other devices normally,
the white light flashes. If communication is abnormal or not
connected, the light is off.
3. Fault indicator
The light is on when the invert is faulty or when external
conditions cannot be grid-connected or when it is working
improperly. When there is no fault, the light is off.
