9.1 Parameter Overview
The parameters of the Sunny Central are preset. If necessary, you can adjust some of the
Sunny Central's parameters to the PV array and to the requirements of the grid management
(see section 3.10 "Grid Management", page 27).
The Sunny Central parameters are summarized in the following parameter groups:
Impaired functionality of Sunny Central due to altered parameters
Improperly altered parameters can partly or completely impair the functionality of the
Sunny Central.
• The parameters marked with * in the parameter overview may only be changed after
consulting with SMA Solar Technology AG.
After work has been carried out on the Sunny Central Control, it must be relocked to prevent
third parties from making unauthorized changes to the parameters (see section 4.2.3 "Locking
the Sunny Central Control", page 32).
