Conext XW PRO 6848 6,800W 48V Installation

Problem Possible cause Solution(s)
Low AC power output or
low surge power. INVERT
LED is on.
AC inductive loads are not
running at full speed.
Insufficient DC current being provided to the
inverter to operate the AC loads.
Check the battery voltage, fuses or breakers and
cable connections.
Make sure the battery bank is sufficient (check for
low DC voltage while running the load).
Make sure the cable length and size is correct
(see the Conext XW Pro Installation Guide for
correct cable). Tie the battery cables together to
reduce inductance.
Apply a load greater than 100 W or disable
Power Save (see "Advanced Features" on
page87).
Inverter goes into invert
mode and starts producing
AC output and then stops
or does not start at all.
Maximum Search Watts setting is too low
or high.
Potential problem loads for search mode:
Incandescent lights have a higher starting
wattage when the filament is cold than the
continuous rating of the bulb.
Fluorescent bulbs draw little power until the
mercury vapor begins to conduct enough
current to light the tube.
Other loads: Some appliances draw power
even when turned off: TVs with instant-on
circuits and VCRs, for example.
If the search sensitivity is set higher than the
combined loads, then connect an auxiliary load
to bring the inverter out of search mode before
the appliances can be turned on.
If the sensitivity is set lower than the combination
of the loads, the loads will remain on and excess
battery drain will occur since the inverter won’t
ever idle.
Another solution is to turn the item off at the wall,
use an extension cord with a rocker switch, a
switch at the outlet, or an appropriate circuit
breaker.
The utility grid is not
dropping out, but the unit is
disconnecting from the
grid.
The AC voltage or frequency provided to the
inverter input is outside the AC Setting
voltage or frequency range.
Adjust the AC1 voltage and frequency settings
(see "AC Settings" on page73). Raise the high
voltage and frequency settings, and lower the low
voltage and frequency settings. If Grid support is
enabled, these limits are over-ridden by the
default anti-islanding AC parameters.
