8. 4 Operating parameters
8.4. 1 Explanation of the Operating Parameters
Warning!
Unauthorized changes to the operating parameters may result in:
•
injury or accidents as a result of changing the internal safety routines
in the Sunny Boy,
• voiding the Sunny Boy's operating approval certificate,
• voiding the Sunny Boy's guarantee.
Never change the parameters of your Sunny Boy without express autho-
rization and instructions.
Name Explanation
ACVtgRPro Surge voltage protection (only relevant for Germany).
In Germany, Sunny Boys can feed into the public grid with up to
260 V AC. However, DIN VDE 10-0126-1 stipulates that the av-
erage AC voltage over 1 minutes must not exceed 253 V. If the
average over 10 minutes exceeds the threshold value of 253 V,
the inverter disconnects itself from the grid. Once the average
over 10 minutes returns to a value of less than 253 V, the inverter
returns to "Working" mode. If surge voltage protection is not re-
quired in the relevant grid area (outside Germany), it can be de-
activated by means of presetting the LDVtgC parameter. In this
event, only the fast cut-off via the Uac-Max parameter inter-
venes.
AntiIsland-Ampl Amplification of the AntiIsland process (alternative AntiIslanding
process, which is deactivated for Germany).
AntiIsland-Freq Repetition rate of the AntiIsland process (alternative AntiIsland-
ing process, which is deactivated for Germany).
Betriebsart Operating mode of the Sunny Boy:
MPP: Maximum Power Point
UKonst: constant voltage mode
(desired voltage is defined in "Usoll-Konst")
IKonst: Operating mode for test purposes
Stopp: disconnection from grid, no operation
