Battery Charger Troubleshooting
To determine the cause of a charger error condition, refer to the troubleshooting solutions
below to resolve the situation.
Problem Possible Cause Solution
AC1/AC2 LED is on, but
will not start charging
(allow 40 seconds to
synchronize).
1) Charger is disabled on the Setup menu. 1) Enable the charger.
2) Charger Block is enabled and the Conext
XW Pro is inside of the charger block time
window.
2) Disable Charger Block if you need to
override this feature.
3) The Conext XW Pro is load shaving. 3) Check the load shave settings. If the load
draw from the grid exceeds Load Shave Amps,
the charger will not operate.
4) Charger is set for 2-stage charging and has
completed a full charge cycle.
4) No action required. The charger comes on
when the battery reaches the Recharge Volts
setting. Otherwise use the Force Charge
setting on the device setup menu to force a bulk
or float charge.
5) Battery voltage is below 40V and AC
source could not be qualified.
5) Recharge the batteries with an external
battery charger or replace the batteries.
6) Gen support is enabled and the draw from
the loads exceeds the Gen support amps
setting.
6) Temporarily disable Gen support mode, or
reduce loads below Gen Support Amps setting.
AC1 or AC2 LED is
flashing, but will not start
charging
(allow 40 seconds to
synchronize).
AC voltage and frequency at the AC input
terminal are within nominal range, but the
inverter output is not yet synchronized to the
AC source. There are four possible causes:
1) The inverter may already be synchronized
to another AC source.
1) The inverter is operating normally.
2) The AC voltage or frequency applied to the
input is outside of the acceptable range of the
inverter.
2) Adjust the AC acceptance settings, see "AC
Settings" on page73, or possibly service an
unstable generator.
3) AC voltage and frequency at the AC input
terminals are within acceptable range, but the
inverter is not yet synchronized to the AC
source.
3) For 120V/240V units, measure voltage in
four places on the input of the inverter: L1-N,
L2-N, L1-L2, and N-Ground. These readings
must be approximately 120, 120, 240, and 0
respectively. Make sure these readings are
within the tolerance for AC acceptance and are
stable for at least 60 seconds.
