a low battery voltage condition exists. The generator can also be started manually by changing
the GenOperation parameter to START. The generator can then be stopped manually by
setting the GenOperation parameter to STOP or by returning it to AUTO.
NOTE: Leaving the GenOperation parameter in the STOP position will not allow
the Sunny Island to operate the generator automatically. If automatic control is
desired, set the GenOperation parameter to AUTO.
GenMan:
The GenMan is an optional unit that may be purchased through your SMA supplier.
The GenMan provides the additional functionality required by generators that are more
complex and need more than a two-wire connection to operate. The GenMan provides the
additional connections as well as warm-up and cool-down functionality. (See the GenMan
manual for more details.) Set the GenControl parameter to GenMan if a GenMan unit is
connected to the Sunny Island.
NOTE: When a GenMan unit is used, manual control of the generator may be
accomplished through the control on the GenMan unit in addition to the
GenOperation parameter in the Sunny Island.
GenOperation
The GenOperation parameter is used to control the generator manually or return it to
automatic control via the Sunny Island. It has five possible settings: Start, Stop, Auto, Run1h
and Release.
Start & Stop: These settings are used as manual overrides to force the Sunny Island to start or
stop the generator regardless of the Sunny Island’s mode.
NOTE: For the Start & Stop functionality to work, GenControl must be set to Direct
or GenMan.
NOTE: Remember, once either of these settings are chosen, the generator will
remain in that state until another command is given. The Sunny Island will NOT
be able to start or stop the generator automatically.
Auto:
The Auto setting returns control of the generator to the Sunny Island. Leave the
GenOperation parameter set to AUTO if automatic operation of the generator by the Sunny
Island is desired.
Run1h: The Run1h setting allows the generator to run for 1 hour from the time it is selected and
then it is shut off automatically. This can be a useful feature if a heavy load is going to be
operated or for a brief charge of the batteries.
NOTE: After the hour of run-time has completed, the Sunny Island will return the
GenOperation parameter to whichever parameter was selected previously. For
example, if the parameter was set to AUTO and Run1h is selected, when the hour
is completed the Sunny Island will return to AUTO. If STOP was selected
previously, then after one hour the Sunny Island would return to STOP.
