• Multi-max scan: by setting this parameter, you can enable/disable the
scan, decide the frequency with which the scan is carried out and over-
ride it manually.
Enable/Disable: Enables/disables the scan for identifying the maximum
power point of the system.
• Scan Interval: this allows you to set the time between scans. It should be
borne in mind that the shorter the scan interval the greater the loss of pro-
duction, due to the fact that energy is transferred to the grid during the scan
but not at the maximum power point. Each scan takes roughly 2 seconds.
• Manual Scan: this allows you to start a manual scan of the photovoltaic
generator (at a different time from the interval set in Scan Interval) in
order to track the maximum power point.
16. Power reduction
This section of the menu allows you to adjust the limit to the active power
that the inverter can feed into the grid by setting the percentage of nomi-
nal power at which the limit should be triggered.
Setting it to 100% resets the default maximum power, which in some
installation country standards may be 110% of nominal power.
17. Input Mode
This section of the menu allows you to set the input configuration mode:
• Independent: Where the two input channels are used separately for
connecting the strings
• Parallel: Where the input channels are connected in parallel to provide
a single input channel
In both cases make sure that the conditions for configuring the input channels described in
this manual are met
18. PMU Board
This section of the menu allows you to adjust the settings for the acces-
sory PMU Expansion Board:
• RS485 Slave: Sets the communication protocol (Aurora or ModBus) for
the RS485 S (Slave) serial communication line
• PMU Mode: Sets the active and reactive power management mode
(PMU – Power Management Unit)
• Analogue inputs: Configures the individual analogue inputs
19. Ethernet Board
This section of the menu allows you to adjust the settings for the acces-
sory Ethernet Expansion Board:
• DHCP: Enables/disables dynamic address allocation for the Ethernet
board.
