Conext XW PRO 6848 6,800W 48V Installation

Problem Possible Cause Solution
Charger amperage drops
off before full charging has
finished (no Event LED).
AC frequency at the AC input terminal may be
out-of-tolerance (too high or low) or the AC
voltage may be outside the Hi AC Volt or Lo
AC Volt settings. AC input voltage
approaching the low disconnect level.
Check the settings on the AC Settings menu.
Check for the correct AC voltage or frequency
at the AC input terminal. If the AC source is a
generator, adjust the AC voltage or frequency
accordingly.
Increase the difference between the Hi AC
Volt (AC1) and Lo AC Volt (AC1) settings to
allow synchronization.
The charge settings are incorrectly configured
for your battery type.
Select the correct battery type or configure a
Custom battery type.
Ambient temperature may be high, causing
unit to overheat and ramp down the charging.
Cool the unit down or check for anything
preventing air flow around the unit.
Battery bank has one or more bad cells or
inadequate wiring.
Check tightness of battery connections and
interconnections. Replace battery.
Battery Management System on Lithium Ion
battery has interrupted charging.
Consult with battery manufacturer for battery
compatibility.
Charger stops before full
charging (or equalization)
has finished.
Event LED flashes and AC
output drops momentarily.
Cold temperature around batteries with
battery temperature sensor (BTS) installed
may be causing unit to reach High Batt Cut
Out setting.
Disconnect BTS during charging or increase
High Batt Cut Out setting.
Charger output is low. Loose or corroded battery connections. Check and clean all connections.
Loose AC input connections. Check and tighten AC wiring connections.
Worn out batteries. Replace batteries.
Battery cables too small or too long. Refer to cable and battery recommendations in
the Conext XW Pro Installation Guide.
Batteries being charged
above the bulk/float
settings.
If a BTS (Battery Temperature Sensor) is
installed, it may be in a cold area or have
fallen off the batteries.
Another DC charging source may be on the
batteries.
Inspect the BTS. Reduce Battery
Temperature Coefficient on Custom
Battery Settings menu.
Battery bank size too small relative to charger
output.
Increase battery bank size or decrease max
charge rate.
Note: To bring batteries that are cold to the
correct state of charge may require charging at
a higher voltage. This may be normal BTS
operation. Unplug the BTS and determine if
your voltage returns to the bulk/float voltage.
