Charger Settings Menu
The Charger Settings menu provides options for configuring the Conext XW+ to
operate from your battery bank.
Table 3-3 Charger Settings Menu
Item Description
Batt Type
Sets the system battery chemistry and type: Flooded (default), AGM , Gel , and
Custom . Selecting Custom displays the Custom Settings sub menu item which
allows you to adjust the settings for each charging stage and
LithiumIon sub
menu item which allows you to adjust lithium ion settings.
Custom Settings Displays the Cust sub menu, where you can adjust settings specific to your
battery type and installation. It is displayed if Custom is selected as the Batt
Type. See “Custom and Lithium Ion Battery Settings Sub Menu Items” on page
3–19.
LithiumIon Displays the LithiumIon sub menu, where you can adjust settings specific to
lithium ion. It is displayed if LithiumIon is selected as the Batt Type. See
“Custom and Lithium Ion Battery Settings Sub Menu Items” on page 3–19.
Batt Capacity Selects the system battery capacity in Ah (amp hours). Setting the Batt
Capacity to 0 resets the charging current to its default values. Zero Ah battery
capacity implies there is no absorption exit current criteria and absorption only
exits when the absorption timer (default 3 hours, range 1 minute-8 hours)
expires.
Max Chg Rate Sets the percentage of the maximum DC output current that is available to the
charger. The maximum DC output current for different models is:
• Conext XW+ 5548 NA—110 A
• Conext XW+ 6848 NA—140 A
If multiple Conext XW+ Inverter/Chargers are charging the same battery bank,
set each inverter's Max Chg Rate to 1/n of the desired charge rate (where n is
the number of inverter/chargers).
Note: Always refer to the battery manufacturer’s specifications before setting
the Max Chg Rate. Do not set the Max Chg Rate above these specifications.
Charge Cycle Sets the charging method: 3-Stage (bulk, absorption, float) or 2-Stage
(bulk, absorption, no float).
Default Batt Temp
Selects the battery temperature charging compensation if a battery temperature
sensor is not installed. In the absence of a battery temperature sensor, the
charger uses one of three settings:
Cool (5 °C/41 °F), Warm (25 °C/77 °F), or Hot
(40 °C/104 °F).
ReCharge Volts When charger is set for 2-stage operation, sets the battery voltage level at
which a new charge cycle begins. ReCharge Volts is automatically
temperature compensated to be consistent with the charge voltage (also
temperature compensated).
Absorb Time
Sets the maximum time spent in the absorption stage, before transitioning to float or
no float.
