7 - Operation
12. Remote Control
This section of the menu allows you to enable/disable the connection/
disconnection of the inverter to/from the grid through the relevant control
signal (R ON/OFF).
• Disable: the connection/disconnection of the inverter to/from the grid is
dictated by the input (voltage from the photovoltaic generator) and output
(grid voltage) parameters of the inverter.
• Enable: the connection/disconnection of the inverter to/from the grid
is dictated by the state of the R ON/OFF signal compared to the GND
signal, as well as by the input (voltage from the photovoltaic generator)
and output (grid voltage) parameters of the inverter.
13. UV Prot. Time
This section of the menu allows you to set the time for which the inverter
stays connected to the grid after the input voltage has dropped below the
Under Voltage limit (set at 70% of Vstart). ABB sets the time at 60 sec.
The user can set it at any time from 1 to 3600 sec.
Example: with UV Prot. Time set at 60 seconds, if voltage Vin drops be-
low 70% of Vstart at 9:00, the inverter stays connected to the grid (taking
power from it) until 9:01.
14. MPPTScan En/Dis
This section of the menu allows you to set the parameters of the maxi-
mum power point tracking (MPPT) function. This function is useful when
there are areas of shade on the PV generator, which may create several
points of maximum power on the operating curve.
Enable/Disable: Enables/disables the scan for identifying the maximum
power point of the system.
15. Scan Interval
This section 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 production, 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.
16. Alarm Message
This section of the menu allows you to set a custom alarm message that
will be shown on inverter’s display in presence of an alarm status; this
function can be enabled/disabled in the relevant menu.
• Enable/Disable: Enables/disables the custom alarm message function
• Compose Message: Compose the custom alarm message using the
inverter’s keyboard (max. lenght of message: 32 chars)
