14.8.1 Authorized charger {1125}
The battery charger function is either activated or not. If this function is not authorized, it is necessary
to charge the batteries using a source of energy not connected to the Xtender.
Where there is lock on the inverter, charger or transfer
function, a small padlock is displayed on the
configuration display.
14.8.2 Battery charge current {1138}
Use this value in order to adapt the charge current to the battery. With this configuration, the
maximum current to be used for charging your battery is adjusted. The current appropriate for the
battery can be found in its technical data. The value set by this configuration is used during the whole
bulk charge phase.
Use this setting to adapt the charge current only with regard to the battery. To adapt
the charge current to your source, use the parameter for maximum current at the
source (Input limit) {1107}.
The right setting of these two values is essential for correct operation as well as the
lifetime of your installation.
If you don’t have any indication of the charge current, the most commonly used
value is a fifth of the capacity. Ex. for 500Ah: 500/5 = 100A.
Caution, if your batteries are in serie, the capacity for the formula above is only that
of one battery and not the sum of them.
14.8.3 Temperature correction coefficient {1139}
If a battery temperature sensor is used (BTS or BSP), the charge and discharge voltages are
automatically adapted to the temperature of the batteries. The compensation is given in millivolts
by degree Celsius (°C) and by battery cell. The discharge thresholds are not compensated.
14.8.4 Undervoltage {1568}
14.8.4.1 Level of battery undervoltage at no load {1108}
Allows adjustment of the battery’s low
voltage level at which the inverter and Smart-
Boost functions are deactivated. This
adjustment is applied in the case of a zero
charge and is automatically adapted with
regard to the power required from the
batteries. This configuration is a factory setting
for lead-acid batteries. Poor adjustment of this
value leads to early ageing of the batteries
due to deep discharges.
A.
Battery voltage.
B. Duration of undervoltage before
disconnection {1190}.
C. Disconnection due to undervoltage.
D. Undervoltage level {1108}.
Adjust this configuration using the technical data for your battery.
