8.1 LED Operation Indicators
Standby (Night)
The inverter is in standby mode. The input voltage is too low for operation.
Initialization
The inverter initializes. The power available from the PV array is not sufficient for standard operation.
Data transmission is not possible during initialization.
If the yellow LED and the red LED light up simultaneously,
the inverter has a ground fault.
The ground fault may also trip the GFDI fuse.
• Observe section 8.2 ”LED Fault Indicators”
(page 66).
In "Turbine" mode, all GFDI fuses are suspended.
In the event of inclement weather or low solar irradiation, all LEDs may light up
simultaneously or flash. This is not an interference.
The inverter is attempting to initialize. The power available from the PV array is not sufficient
for standard operation.
