Studer Innotec RCC-02, RCC-03 USE OF A LIMITED POWER SOURCE

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.

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.

USE 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.
