isplay access and settings
Once the inverter has been commissioned, it is possible/necessary to
configure the inverter by accessing the Settings Menu directly from the
display. The following are the main adjustable parameters (see the sec-
tion on “
Menu descriptions
”)
• RS485 address:
setting required in the case of system monitoring via
the RS485 line
• Vstart:
setting required if requested by the configurator during the sy
-
stem sizing procedure ("Vstart" parameter)
• MPPT scan:
allows maximum power point tracking with settable sensi-
tivity and time interval ("MPPT" parameter).
• Setting of analogue inputs (if any):
allows you to set the parameters
of the analogue sensors connected to the input (“Analogue Inputs”).
• Input Strings (where present):
setting necessary for checking the
status of the fuses and the unbalance of the string currents at the input
(“Fuse control” parameter).
• Reactive power feed-in setting (where present):
setting necessary
for managing the different ways of feeding reactive power into the grid
(“Reactive Power" parameter)
• Active power limitation setting (where present):
setting necessary
to set a limit on the active power supplied by the inverter (“Power reduc-
tion” parameter)
