14.1.7 Operation Together With Sunny Boys

If the battery is fully charged, the frequency limits the power output of the AC feed-in
generators (Sunny Boys). If the generator is now manually started, for example, the
frequency would be lowered, if required, as the Sunny Island 5048 synchronizes with
the generator. The AC feed-in generators (Sunny Boys) would then feed additional
energy into the system and possibly overload the batteries. In order to prevent this
during such conditions, the stand-alone grid frequency is temporarily increased
("#230.04 AcSrcFrqDel" parameter), in line with the synchronization, until the AC feed-
in generators (Sunny Boys) are disconnected from the stand-alone grid as a result of the
grid limits being exceeded.

14.1.8 Stopping the Generator

If the Sunny Island 5048 (automatically or manually) has started the generator, it can
be manually stopped at any time using the "#430.01 GnManStr" parameter. This
disconnects the generator (the minimum run time is not taken into account here) and the
power down time (Cool) is skipped. Afterwards, the system transitions into the stop time
(Lock).
If the generator start is performed directly at the GenMan or the
generator, it can only be stopped there again. Triggering a stop here only
disconnects the generator and the system transitions into the stop time
(Lock).
Generators with the manual start option can generally only be started and
stopped at the generator.
If the generator start is to be disabled after a manual stop, this must be performed
by setting the "#241.01 GnAutoEna" parameter to Off.
