14.4 Sunny Mini Central Operating Parameters
14.4.1 Explanation of the Operating Parameters
Unauthorized changes to the operating parameters may result in:
•
•
injury or accidents as a result of changing the internal safety
specifications of the Sunny Mini Central,
specifications of the Sunny Mini Central,
•
voiding the Sunny Mini Central operating approval certificate,
•
voiding the Sunny Mini Central warranty.
Never change the parameters of your Sunny Mini Central without express
authorization by the local energy supply company and instructions from
SMA.

Explanation
ACVtgRPro
Voltage rise protection (only relevant for Germany).
The Sunny Mini Central can feed into the public grid 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 Sunny Mini
Central disconnects itself from the grid. Once the average over 10
minutes returns to a value of less than 253 V, the Sunny Mini Central
returns to "Working" mode. 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.
