6.4.3 Sunny Boy 4200TL Operating Parameters
Any unauthorized modifications of the operating parameters
can
• Result in serious injuries or casualties due to altered inter-
nal safety precautions within the Sunny Boy
• Void the operating permission of the Sunny Boy
• Void the warranty of the Sunny Boy.
Never change the operating parameters without explicit per-
mission and instructions!
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 A/
Vconst-SetpointA V 0 ... 750 290 PV setpoint voltage for constant voltage
operation for String A and B. These
parameters only are important in case the
parameter „Operating Mode“ is set to „U-
konst“.
Usoll-Konst B/
Vconst-SetpointB V 0 ... 750 290
NiTest/
impedance test 0 / 1 1 Activates (1) and deactivates (0) the
automatic failure current 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 V 180 ... 300 198 Lower (Uac-Min) and upper (Uac-Max) limit of
permissible AC voltage (Anti-Islanding)
Uac-Max V 180 ... 300 260
Fac-Delta- Hz 0 ... 4.5 (0.19) 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-MAX mOhm 0 ... 2000 350 Maximal „rate of change of grid impedance“
before anti-islanding trips
Riso-Min kOhm 1000 ... 30000 1000 Minimum irradiation resistance
