90 SI4548_6048-US-TB_en-13 Technical description
The Sunny Island is configured as master.
The Sunny Island is configured as slave 1.
The Sunny Island is configured as slave 2.
Status of the external source:
Voltage and frequency of the generator/grid are within set limits.
Status of the external source:
Voltage and frequency of the external source are not within set limits. In this case,
the Sunny Island does not connect the generator to the stand-alone grid.
Status of the external source (at position (E) on the display):
The maximal admissible generator reverse power was exceeded and the
Sunny Island has disconnected the generator from the stand-alone grid.
"Battery" request reason:
The generator has been requested as a result of the battery state of charge.
"Cycle" request reason:
The generator was requested via the generator operation's time-dependent
repetition cycle (Parameter: 235.17 GnTmOpCyc).
This symbol can only be shown in Multicluster operation.
"External" request reason:
The generator was requested via the extension cluster. This request can only take
place in multicluster operation.
"Load" request reason:
The generator has been requested as a result of the load-dependent generator
request.
"Start" request reason:
The generator has been requested by the operator manually setting the generator
request in the Sunny Island from "Auto" to "Start". The generator is then no longer
automatically controlled or switched off by the Sunny Island.
"Time" request reason:
The generator was started for one hour using the "Run1h" setting in the
Sunny Island. Once this time has passed, the Sunny Island automatically switches
off the generator.
Display for relays (solid circle = the relay is activated; empty circle = the relay is
deactivated).
