6.4 Connecting the AC Output
6.4.1 Requirements
For connecting the AC output, the following requirements must be satisfied:
1. Connection Requirements
When connecting an inverter to the public grid, follow the connection requirements
of the local grid operator!
The Sunny Mini Central is designed for operation on 220 V - 240 V grids.
Additionally, it is equipped with an automatic grid frequency identifier and can
thus be connected to a 50 or 60 Hz system without further parameterization.
The following limit values for the AC output apply:
Limit values for AC output
Voltage range
(default setting per DIN VDE 0126-1-1)
198 V - 253 / 260 V
a)
Voltage range
(adjustable operating range)
180 V - 265 V
Frequency range
(default setting per DIN VDE 0126-1-1)
47.5 Hz - 50.2 Hz
Frequency range
(adjustable operating range)
50 Hz: 45.5 Hz - 54.5 Hz
60 Hz: 55.5 Hz - 64.5 Hz
a) The Sunny Mini Central can temporarily feed power into the grid with a
maximum output voltage of 260 V. However, DIN VDE 0126-1-1
stipulates that the average voltage over 10 minutes must not exceed 253
V. That means for example, if the grid voltage is constantly 254 V, the
inverter disconnects itself from the grid. In this case, contact the local grid
operator for assistance.
DIN VDE 0126-1-1 only applies in Germany. See section 14.4.3
"Country-specific Parameter Settings" (Page 89) for all other preset
country values of your inverter.
