Adjustable Parameters
You can change the following parameters for voltage and frequency monitoring with a
communication product (e.g. Sunny Explorer) (see Section 8.2 "Changing Operating Parameters",
page 39).
With voltage changes, only the phase voltages are considered. If the set values
are present as line-to-line voltages, these have to be converted to phase volt-
ages.
