Item Description
Batt Type
Sets the system battery chemistry and type:
Flooded
(default),
AGM
,
Gel
,
LithiumIon
,
and
Custom
.
Selecting Custom displays the Custom Settings item, which allows you to adjust the
settings for each charging stage.
Custom
Settings
Displays the Custom Battery Settings menu, where you can adjust settings specific
to your battery type and installation. It is displayed if Custom is selected as the Batt
Type. Further custom settings for Lithium Ion batteries appear if Lithium Ion is
selected as the Batt Type.
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
Tem p
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.
Chg Block
Start
Sets the time to halt charging on AC1 (Grid). The AC2 (Gen) port is unaffected by the
Conext XW+ block settings. The charger block start and stop settings allow you to
select when the charger stops charging on AC1. To disable the charger block function,
set Chg Block Start and Chg Block Stop to the same time. See “Charger Block” on
page 3–31.
