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).
These 2 screens are displayed at inverter start-up:
One of the following two screens may be displayed while waiting for the connection,
depending on conditions:
While the system is checking the grid connection, the yellow LED next to the display
will be lit up constantly and the green LED will be flashing;
When waiting for solar radiation ("Waiting sun"), the yellow LED will be off while
the green LED will be flashing.
As soon as the "Vac absent" and "Awaiting sun" conditions have been successfully
satisfied, the inverter will start the inverter connection procedure. Depending on the
type of grounding, different controls will be performed and different screens shown.
