8.4 Operating Parameters

8.4.1 Explanation of the Operating Parameters

Name Explanation

ACVtgRPro Voltage rise protection (only relevant for Germany).

Sunny Boys can feed into the public grid in Germany with up to

260 V AC. However, DIN VDE 0126-1-1 stipulates that the

average AC voltage over 10 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

resumes grid feeding. If voltage rise protection is not required in

the relevant grid area (outside Germany), it can be deactivated

by presetting the LDVtgC parameter. In this event, only the fast

cut-off via the Uac-Max parameter intervenes.

AntiIsland-Ampl Amplification of the AntiIsland process (alternative anti-islanding

process, which is deactivated for Germany).

AntiIsland-Freq Repetition rate of the AntiIsland process (alternative anti-

islanding process, which is deactivated for Germany).

Betriebsart Operating mode of the Sunny Boy:

MPP-Betrieb: Maximum Power Point

Konstantspg.: constant voltage mode (nominal voltage is

defined in "Usoll-Konst").

Stop: disconnection from grid, no operation.

Turbine: operating mode for wind turbine systems.

Default Used for setting country-specific information.

GER/VDE0126-1-1: country-specific parameter settings for

Germany in accordance with DIN VDE 0126-1-1.

SP/RD1663: country-specific parameter settings for Spain.

GB/G83: country-specific parameter settings for Great Britain.

Other: here, parameter settings can be defined for countries for

which no predefined setting exists.

Trimmed: if country-specific parameters have been changed,

"trimmed" is shown on the display.

Off_Grid: settings for inverters which are operated in a stand-

alone grid. More detailed information can be found in the Sunny

Island manual.
