Initialization
all LEDs are on
The Sunny Boy control system is initializing.
The string voltage to the inverter is between approx. 120 V and 240 V. The supply is suf-
ficient for the system control and not quite sufficient for feeding to the grid. Data trans-
mission is not possible.
NOTE: In some seldom cases (bad weather, low solar radiation) the LEDs
can go on all at once and off again. This "blinking" results from the fact
that the incoming radiation is not high enough for the Sunny Boy to keep it
stable. Note: This is not a malfunction!
