411 Current overview
The software of the solar inverter determines whether a warning is
given or a failure occurs.
For problems with the insulation or grounding, you can use the
230
Grounding
menu to define whether a warning is given or a failure
is triggered (see Chapter
“10.13 Insulation and grounding monitor-
ing”, p. 61).
The individual message categories are displayed as follows:
