Fig. 8.6: Menu “PARGRD“ (3+4)
The Sunny Island is informed about the operating values of the connected AC grid
with the settings in the menu “PARGRD“ (3+4). These values are the voltage and
frequency which the Sunny Island, being the grid-forming device, has to make avail-
able. In addition these are limiting values. When these limits are exceeded the Sunny
Island in grid-tied operation detects this state as an error.
After changing the parameter “401_Phase Mode“ the Sunny Island
must be restarted (for example in the menu “FUNCT” (2+3), see
chapter 7.3).
