13.4 Sunny Mini Central operating parameters

Unauthorised changes to the operating parameters may result in:
• Injury or accidents as a result of changing the internal safety routines
in the Sunny Mini Central.
• Voiding the Sunny Mini Central's operating approval certificate.
• Voiding the guarantee of the Sunny Mini Central.
Never change the parameters of your Sunny Mini Central without express
authorization by the local energy supply company and instructions from
SMA.

13.4.1 Explanation of the operating parameters

Name Explanation
ACVtgRPro Surge voltage protection (only relevant for Germany).
The Sunny Mini Central 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 10-minute average exceeds the threshold value of 253 V, the
Sunny Mini Central disconnects itself from the grid. Once the 10-mi-
nute average returns to a value of less than 253 V, the Sunny Mini
Central returns to "Working" mode. If surge voltage protection is not
required in the relevant grid area (outside Germany), it can be
deactivated by means of 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
(deactivated for GER by setting AntiIsland-Ampl = 0)
