3.3.4 Description of Operating States
Stand-by at Night
The Sunny Boy 2800i is in so-called stand-by operation. This state
is reached if the input power at the inverter is too low for feeding
operation (U
PV
< ca. 80 V) and not sufficient for normal
operation)
Initialization
The on-board computer of the Sunny Boy 2800i is in the
initialization phase. At least one of the string voltages on the
inverter is between approx. 80 V and approx. 220 V. Power is
already supplied to the internal board, but is not yet sufficient for
grid feeding. Data transmission is not possible yet.
