6.4.3 Sunny Boy 2800i Operating Parameters
Name Unit Range Default Description
E_Total kWh 0 ... 200000 Total energy yield (E_Total) and total operating hours
(h_Total) of the inverter. Changing the value can be
necessary when a Sunny Boy is exchanged and you
wish to match the previously acquired data
h_Total h 0 ... 200000
Usoll-Konst V 250 ... 600 600 PV setpoint voltage for constant voltage operation. The
parameter is only important in case the parameter
„ Betriebsart“ is set to „ U-konst“
I-NiTest/
impedance test mA 0 ... 15000 9000 Activates (9000) and deactivates (0) the automatic
impedance measurement. This parameter only takes
effect when the Sunny Boy was deactivated (by
disconnecting from the AC utility) or set to operating
mode „ Stop“
Uac-Min/Vac-Min V 180 ... 300 198 Lower (Uac-Min) and upper (Uac-Max) limit of
permissible AC voltage (Anti-Islanding)
Uac-Max/Vac-Max V 180 ... 300 260
Fac-Delta- Hz 0 ... 4.5 0.19 Maximal frequency above (Fac-Delta+) and below
(Fac-Delta-) 50 Hz grid frequency before anti-islanding
trips
Fac-Delta+ Hz 0 ... 4.5 0.19
dFac-MAX Hz/s 0.005 ... 4.0 0.25 Maximal „ rate of change of frequency“ before
anti-islanding trips
dZac mOhm 0 ... 2000 350 Maximal „ rate of change of grid impedance“ before
anti-islanding trips
Upv-Start V 250 ... 600 300 Minimum voltage the Sunny Boy needs in order to
initiate normal operation.
T-Start s 5 ... 300 10 Parameter relevant for start time. Counts seconds after
minimum PV voltage is exceeded
T-Stop s 1 ... 1800 2 Parameter relevant for the MPP-tracking. Do not
change.
Betriebsart/
Operating Mode MPP/Ikonst/
UKonst/Stop MPP Operating Mode of the Sunny Boy:
MPP: Maximum Power Point
Ukonst: Constant Voltage Mode (Setpoint defined in
„ Usoll-Konst“)
IKonst: Experimental mode / special applications
Stop: Disconnection from utility, no operation
Speicherfunktion/
Memory Function none Default Parameter: Sets all parameters to default
Reset Betriebsdaten: Sets all parameters that are visible
in user level to default values.
Reset Fehler: Resets a permanent device disable (dBh)
Default GER/ENS Used for adjusting the parameters country specific
settings
Table 6.1: Operating Parameters of the Sunny Boy 2800i (changeable)
Any unauthorized modifications of the operating parameters can
1. Result in serious injuries or casualties due to altered
internal safety precautions within the Sunny Boy
2. Void the operating permission of the Sunny Boy
3. Void the warranty of the Sunny Boy
Never change the operating parameters without explicit
permission and instructions!
