RCC

USE TO INCREASE THE POWER ON AN EXISTING INSTALLATION

Description:

The availability of an inverter or a inverter/charger allows its power to be extended with an Xtender connected in cascade. The maximum power of the first inverter is limited by the maximum current from the transfer relay of the Xtender.

Associated current configurations:

•Maximum current of the AC source {1107} Adjust this configuration in relation to the maximum current that can supply the old inverter.

•Locking: Smart boost inactive {1126} Suppress the locking of this function: This way, when the first inverter has reached it maximum power, the power consumed that will be supplied by the Xtender could be increased.

•Locking: Inactive charger {1125} This lock, without which the battery energy would be taken by the first inverter, is returned by the Xtender charger. This would only have the effect of discharging the battery with losses caused in the two inverters or inverter/chargers.

LOAD SHEDDING OF THE SECOND PRIORITY LOADS

Description:

Consumers with different supply priorities allow automatic disconnection of the supply to consumers of lower priority if the battery becomes weak. The supply of the priority loads is thus assured, such as lighting or computers, for example. In this case, the low-priority loads must be cabled via one of the auxiliary relays. The reference for the example below correspond to the auxiliary contact no 1.

Associated current configurations:

•Communication mode {1202}

•Relay activated by the battery voltage {1245}

•Voltage 1 active {1246}

•Voltage 1 {1247}

•Duration 1 active {1248}

•Voltage for deactivation of the auxiliary relay {1255}

•Duration for deactivation {1256}
