U
SE 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.
L
OAD 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}
