SMA SUNNY ISLAND 5048-US - Generator Operation; Manual Generator Operation

Connecting External Sources SMA America, LLC
118 SI5048U-TUS121440 Technical Description
The following figure shows the wiring for a generator capable of autostart:
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 the generator is externally stopped,
this is detected, the generator is disconnected and the off-grid power system is continued to be
supplied.
14.1.3 Generator Operation
The Sunny Island allows automatic operation (depending on charge state or load) (see section
14.1.5”Automatic Generator Operation” (page120)). 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:
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 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.
