Required parameter settings
The installer has to set the parameters listed in Table 13.3. The values are of course
only examples. The generator is defined to be grid forming and is assumed to be of
type 2. A current and voltage measurement for the generator should be installed.
See chapter 3.4.5 for details.

Table 13.3: Summary of parameters to be configured
Even in island grids with feeders independent of weather conditions we
recommend to wire up the consumers in a way so as to be able to switch
them off with the Sunny Island (via one of the relays K1 to K8). Espe-
cially in case of a failure (generator defective etc.) the battery can thus
