Fig. 7.3:
Menu “START“ (2-1)
By confirming the menu entry ”START” in the menu ”START” (2-1) the Sunny Island
can be switched from standby operation to the operating mode configured before. As
a default setting this is the operation as a grid-forming element (”RUN_U”) where the
Sunny Island forms the island grid and supplies the connected consumers. The oper-
ating mode – grid-forming (“RUN_U”) or grid-tied (“RUN_I”) – is stipulated by setting
the parameter ”602_GenSet Type” in the menu ”PARGEN” (3+6).
Even in grid-tied operating mode the Sunny Island may be transitorily
grid-forming. This is the case if no voltage has been found in the island
grid.
When starting up, the Sunny Island will shortly beep, as an acoustic warning.
By confirming the menu entry ”STOP” the Sunny Island is switched back into standby
mode. In an island grid without any other grid-forming component this means that no
AC voltage is on any more.
When the Sunny Island is started from the state it has been delivered
in, the start-up must be made manually. The inverter can also be con-
figured to an automatic (re-)start (see Chapter 8.3).
