Note, that if the smart boost function is activated, it is possible to discharge the
battery even if the inverter function is locked.
Authorised charger {1125}
The battery charger function is either activated or not. If this function is not authorised, it is
necessary to charge the batteries using a source of energy not connected to the Xtender.
Smart boost authorised {1126}
The function Smart-Boost is deactivated by default. In this case no assistance will be provided to
the source and if the source is overloaded, the energy from the battery is not drawn. Do authorise
this function if you have a low power source (generator, shore power or camping plug) and you
want more power available.
When the smart boost function is active, it is possible to discharge the batteries,
even if the Xtender is connected to a source and the charger is active.
Authorised transfer {1128}
The transfer relay is authorised or not. If the transfer is not authorised, a correct voltage at the AC IN
input will not be transferred to the output and to the users. The battery charger function is not
possible and the Xtender operates only in inverter mode.
Automatic restart {1129}
In the event of an anomaly on the installation, the combi Xtender stops automatically. Depending
on the seriousness of the fault, when this disappears, the Xtender may restart automatically without
any user intervention (fault confirmation). The following functions allow the events for automatic
restart to be defined.
• After battery undervoltage {1130}
• Number of battery under voltages allowed before final stop {1304}
• Leadtime to counting the battery under-voltages allowed before final stop {1404}
• Number of critical battery under-voltages before final stop {1305}
• Leadtime to counting the critical battery under-voltages allowed before final stop {1405}
• After battery overvoltage {1131}
• After inverter or smart boost overload {1132}
• After overtemperature {1134}
Whatever the restart method, the event is recorded in the event history so that it
can be called at any time.
Number of battery under-voltages allowed before final stop {1304} and
Leadtime to counting the battery under-voltages allowed before final stop {1404}
If battery under-voltage faults occur to your system, the inverter and Smart-boost functions are
deactivated in order to protect the battery against deep discharges.
These functions can be reactivated automatically if the fault disappears. With the parameter
{1304}, you can adjust the number of the faults before these functions are definitely deactivated. In
this case, an intervention is necessary to reactivate these functions (fault acknowledgement).
The duration parameter allows setting the time during which these faults can be repeated.
Once this duration has come to an end, if the number of faults is not reached, the counter goes
back to 0 and the faults can occur again.
To cancel the automatic reactivation, set 1 for the number of battery under-
voltages allowed before final stop.
For a permanent automatical reactivation, set 0.
