17.3 USE TO INCREASE THE POWER ON AN EXISTING INSTALLATION
The availability of an inverter or an 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.
17.4 LOAD SHEDDING OF THE SECOND PRIORITY LOADS
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 corresponds 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}
