The generator is disconnected by the Sunny Island after the GENRDY signal has been withdrawn by
the GenMan.
14.1.3 Generator Operation
The Sunny Island allows automatic operation (depending on charge state or load)
(see 14.1.5 ”Automatic Generator Operation” (page 109)). In addition, manual operation is also
possible.
14.1.4 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:
An equalization charge can be manually started using the "520.01 ChrgSelMan" parameter.
This sets the battery management (see 13 ”Battery management” (page 92)) into the equalization
charge state and requests the generator. This request persists until equalization charge has been
completed.
The following process diagrams provide an overview of the start/stop behavior of the Sunny Island
during manual generator operation:
NOTICE!
Occurrence of unpredictable operating states.
• Never carry out a manual start directly at the generator.
• Observe the indications in the GenMan manual.
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 ChrgSelMan" = Start).
Stop:
The generator is stopped manually. The current generator request is canceled −
immediate disconnection from generator and change to lock state. Once the lockout
time has ended, the generator switches into automatic operation. The generator can
only be started manually as long as it is in the operative type "Stop".
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.
