LED Operation Indicators
Standby (Night)
The inverter is in standby mode because the input voltage is too low for operation.
Initialization
The inverter is initializing. The power from the array is sufficient to operate the
control, but not yet powerful enough to begin feeding the grid. Data transmission is
not possible during initialization.
Occasionally, during inclimate weather or low solar radiation, the LEDs may all turn
on at once and then go off again. This indicates that the inverter is trying to initialize
but the power available from the array is not sufficient to operate. This is not a
malfunction.
