APPLICATION EXAMPLES
The examples below illustrate some implementation options for current installations. Useful
configurations for these situations are also given. These are common and non-obligatory
configurations.
For more details on each configuration shown, please refer to the complete description given
above in this manual.

HARGER WITH GRID
Description:
In this configuration, the Xtender is connected to a
grid with high power output. The basic functions
are configured for this type of application. The
loads are supplied by the grid via the transfer relay
and this helps to charge the battery. In the event
of a disconnection from the grid, the transfer is
stopped and the inverter is activated
automatically.
Associated current configurations:
• Battery charge current {1138} Adapt this configuration to the technical data for the batteries for
the best charging capacity.
• Adjustment of the standby level {1187} Adjust this configuration if the minimum load has not
been detected or, conversely, if the inverter remains engaged when all the loads have been
deactivated.
Additional configurations:
• Battery curve {1140} {1156} {1157} Adapt these configurations in order to adjust the voltage levels
and the durations of charge to your battery manufacturer’s data.
U
SE OF A LIMITED POWER SOURCE
Description:
For example, a source such as a generator, a
camping or dock connection. In this case the
power available is limited. In the case of high
power consumers the source is insufficient and
needs an assistance by means of the energy
stored in the batteries.
Associated current configurations:
• Maximum current of the AC source {1107} By adjusting this configuration to the maximum current
that the source can supply, the power available is ideally shared between the battery charging
and the consumers. For example, if a load is deactivated, the battery charger current is
automatically increased.
• Locking: Smart boost active {1126} In the event that the maximum source current is exceeded,
the inverter supplies the energy required to keep the source current at the set maximum level.
Thus, the inopportune stopping of the generator is avoided, the circuit breaker of the dock or
camping connection is not activated and the supply of the loads is assured.
• Option of exceeding the power sharing value without opening the transfer relay {1436}. Allows
retention of the drawn transfer in the event of consumption of peak currents such as compressor
startups.
