Connection of the system to the grid

The two-line LCD display is located on the front panel, and shows the following:
The operating status of the inverter, and statistical data;
Service messages for the operator;
Alarm and fault messages.
During regular operation, the display will cycle through available data. The screens
change every 5 seconds, or can be changed manually by pressing the UP and
DOWN keys (see Fig. 20).
At inverter start-up, these 2 screens are displayed:
The following screens may be displayed while waiting for connection, depending
on conditions:
Vac absent
While the system is checking if grid voltage is present, the yellow LED next to the
display will be lit up constantly and the green LED will be flashing.
When in "Awaiting sun" condition, the yellow LED will be off and the green LED
will be flashing.
As soon as the "Vac absent" and "Awaiting sun" conditions have been successfully
satisfied, the inverter starts the connection process. Depending on the type of
grounding, different checks will be performed and different screens displayed.
If the system is grounded (one of the two poles connected to the ground) then the
first screens will read as follows
