SUNNY ISLAND 5048 - Technical Description - Wind & Sun Ltd.

Connecting External Sources SMA Solar Technology AG
The generator is disconnected by the Sunny Island after the GENRDY signal has been withdrawn by
the GenMan.
NOTICE!
Occurrence of unpredictable operating states.
• Never carry out a manual start directly at the generator.
• Observe the indications in the GenMan manual.
14.1.3 Generator Operation
The Sunny Island allows automatic operation (depending on state of charge or load)
(see 14.1.5 ”Automatic Generator Operation” (page 114)). 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
"540.01 GnManStr" parameter. Here, a distinction is made between the following operating modes:
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 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.
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 ChrgSelMan" parameter.
This sets the battery management (see 13 ”Battery Management” (page 97)) in the equalization
charge state and the generator is requested. 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:
