Operation 93
By default, the display backlight is ON when the inverter is in operating mode. When
the inverter is in sleep mode, the control unit and display switch OFF completely. The
control unit wakes up and the backlight illuminates if the keypad is activated.
If the keypad is not used for a preset time when the inverter is in operating mode, the
Sun display shall appear automatically.
The user can set the reduced backlight function ON/OFF to dim the backlight when
the keypad is not used for a preset time period. The reduced backlight function is
mainly designed to be used when the Control unit is remotely mounted, for example
on a bookshelf in a residential house.
Events submenu
This is subdivided into two menus, one for faults and the other for events. In both
cases the view shows the date and nature of the fault or event. Push the Help (?)
button to see any available additional information about the event.
Events remain in the event log even after the faults have been solved. The inverter
automatically removes the oldest items from the event log when there is insufficient
memory to store new events.
Communication submenu
Contains the parameters that are needed to set up communication to other systems.
The purpose of the menu is to show a subset of the parameter groups which are used
to set up communications. Panel communication parameters shall be accessible in
this submenu. Other parameter groups are not accessible through this submenu.
If there are any assistants for communications settings, they shall be accessible
through the communications menu.
System info submenu
The System information submenu allows you to see the control panel version
information.
Self test submenu
The self test assistant is used to perform an automatic protection test of the inverter in
four stages (overfrequency, underfrequency, overvoltage and undervoltage). The
inverter temporarily disconnects from the grid during the test.
To perform the test the system should be completed and ready to start operation, and
the photovoltaic array should be exposed to adequate solar radiation. The duration of
the test varies, partly due to country-dependent regulatory delays for reconnection.
The test may take a few minutes to complete. It is not possible to exit the test once it
has started. The final screen of the assistant shows whether or not the inverter
passed the tests.
