The generator is disconnected by the Sunny Island after the GENRDY signal has been withdrawn
by the GenMan.
Caution!
A manual start directly at the generator is not possible (see GenMan manual).
Unforseeable operational states could result (see the GenMan manual).

13.1.3 Generator Operation

The Sunny Island allows automatic operation (charge state- or load-dependent) (see 13.1.5
"Automatic Generator Operation" (Page 137)). In addition, manual operation is also possible.

13.1.4 Manual Generator Operation

The manual operating modes for the generator management are triggered using the "540.01
GnManStr" parameter. The following operating modes are distinguished:
Auto:
In this operating mode, the generator is automatically started due to the settings. This
includes the start via the state of charge or the consumer power or by the request for
a manual equalization charge.
("520.01 ManChrgSel" = Start).
Stop:
The generator is stopped manually. Cancels the present generator request –
immediately disconnects from the generator and transitions into the lockout state.
Once the lockout time has ended, the generator switches into automatic operation.
The generator can now be started manually.
Start:
Manual generator start – the generator runs "continuously" until stopped. The
generator can only be stopped manually.
Run1h:
Operation for one hour. Once the lockout time has expired, the transition back into
automatic mode follows.
An equalization charge can be manually started using the "520.01 ManChrgSel" parameter. The
battery management (see section 12 "Battery management" (Page 120)) is set into the equalization
charge state and requests the generator. This request persists until equalization charge has been
completed.
The following sequence charts provide an overview of the start/stop behavior of the Sunny Island
in the case of automatic generator operation:
