46 V4.4.0 User manual
The battery undervoltage level is automatically adapted to the instantaneous power
of the consumers to compensate for internal losses in the battery and cables.
14.8.4.2 Dynamic compensation of the batteries undervoltage {1531}
14.8.4.2.1 Dynamic battery undervoltage compensation {1191}
This setting allows you to activate (or not) the dynamic battery undervoltage compensation. If this
setting is deactivated, the disconnection voltage is identical, whatever the charge on the inverter of
the Xtender.
14.8.4.2.2 Type of dynamic compensation {1532}
This parameter enables you to choose between an automatic and a manual dynamic
compensation. If you use the manual compensation, you must adjust the parameter {1109}
"Undervoltage at full load".
Using the manual mode of dynamic compensation in systems with several Xtenders
may cause malfunctionning of the system as the Xtender will not take into account
the voltage of the other inverter-chargers.
14.8.4.2.3 Low voltage disconnection at full-load {1109}
The battery undervoltage is adapted to the nominal current of the inverter (dynamic undervoltage
compensation). You can adapt the disconnection voltage to the nominal charge of the inverter,
according to your battery specifications.
14.8.4.3 Duration of undervoltage before disconnection {1190}
If the battery voltage is beneath the disconnection threshold, the inverter and Smart-Boost functions
are deactivated, but not immediately. This setting allows you to adjust the delay between falling
below the disconnection threshold and the current disconnection.
14.8.4.4 Reactivation voltage after battery undervoltage {1110}
When the Xtender has shut off the inverter function following a battery undervoltage, it starts up
again if the battery voltage returns to acceptable value. This setting allows you to fix the voltage at
which the inverter and Smart-Boost functions are reactivated.
14.8.4.5 Adaptable low voltage disconnection (B.L.O) {1194}
A battery permanently operating when it is practically discharged sees its lifetime drastically
reduced. In order to force the client to recharge the battery, the undervoltage threshold may be
increased with each undervoltage disconnection. The low threshold is increased with each
disconnection, and returns to its original value if the battery has been recharged up to a certain
voltage. For this reason, the client will not be able to constantly discharge the battery without at least
having recharged it. The algorithm B.L.O. (Battery Lifetime Optimizer) is activated with this parameter.
14.8.4.6 Max voltage for adaptive low voltage {1195}
The undervoltage threshold is increased with each undervoltage, but never higher than the value
set with this parameter.
Be aware that this value is limited to the voltage of the fully charged battery
