Operation SMA Solar Technology AG
80 SI5048-TB-TEN110340 Technical Description
"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 only applies to
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).
Warning message:
This symbol blinks until you have confirmed the warning or the error in the menu
"410# Failures Current" or "420# Failure History".
Display "Generator Status" and "Request Reason"
The two displays above are cyclically shown on the display as the status of the external
source.
Example:
If the display changes every 3 seconds from "*" to "B", this means that the generator
voltage and frequency lie within the set limits and that the generator was requested as a
result of the battery state of charge.
Stopping the generator manually
If the generator has been manually set to "Stop", then no generator status information is
shown on the display. The field remains empty in this case.
Indications of a warning
If faults occur, the device switches into standby mode and shows the fault on the display.
The fault must be eliminated and confirmed, then the Sunny Island carries out an autostart.
