122 SI4548-6048-US-BE-en-21 Operating Manual
If the generator is started manually in this operating mode, the Sunny Island detects the running
generator and connects it once the warm-up time has expired. If you stop the generator externally,
this is detected, the generator disconnected and the stand-alone grid is still supplied.
14.1.3 Generator Operation
The Sunny Island allows automatic operation (depending on the state of charge or load) (see
Section14.1.5 "Automatic Generator Operation", page123). In addition, manual operation is also
possible.
14.1.4 Manual Generator Operation
The manual operating modes for the generator management are tripped using the parameter
"540.01 GnManStr". Here, a distinction is made between the following operating modes:
Generator request
If the generator is running after being externally started and a generator request occurs, the
GnReq signal is disabled until the generator is externally stopped again and the stop time has
expired.
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 load power or by the request for
a manual equalization charge.
("520.01 ChrgSelMan" = Start).
Stop: The generator is manually stopped. 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.
Start: Manual generator start – the generator runs "continuously" until stopped. The
generator can only be manually stopped.
