6.1 Changing Operating Parameters
The operating parameters of the inverter are set to certain values by default. You can change the
operating parameters to optimize the performance of the inverter.
This section describes the basic procedure for changing operating parameters. Always change
operating parameters as described in this section. Some function-sensitive parameters can only be
viewed by qualified persons and can only be changed by qualified persons by entering the
personal SMA Grid Guard code.
