Conext XW Pro Installation Guide
Battery Bank Requirements
The DC voltage of the Conext XW Pro must match the nominal voltage of the system
and battery-connected devices. The inverter is a 48 V inverter; therefore, the battery bank
and battery-connected devices in the system must be configured for 48 volts.
Note: The minimum recommended battery bank is 440Ah per inverter/charger. The
Conext XW Pro is designed to operate with batteries and should not be operated
without them. Also, do not allow the battery bank to become completely discharged. If
the voltage of the battery bank falls below 40volts, the Conext XW Pro will not operate.
Battery Cable Requirements
WARNING
OVERHEATING OF DC TERMINALS AND CABLES
Overheating of the DC terminals or DC cables to dangerous temperatures may occur due to
improper installation.
n Do not put anything between the cable lug and the terminal surface.
n Do not over-tighten connections; observe all recommended torque values.
n Do not apply any type of anti-oxidant paste until after the cable connection is tightened.
n Do not under size cables; install cables sized in accordance with national electrical
code requirements.
n DC cables must have crimped copper compression lugs or crimped and soldered
copper compression lugs; soldered connections alone are not acceptable. Lugs must
be rated for use with fine-stranded cable.
n Do not use coarse-stranded cable; the lack of flexibility may pull DC terminal
connections loose.
Failure to follow these instructions can result in death, serious injury, or equipment
damage.
Battery cable length
Cable runs should be kept as short as practical. Length should not exceed 10 feet. Run
the positive and negative cables alongside each other. Avoid cable loops.
In order to keep the battery cable length short, install the Conext XW Pro as close as
possible to the battery room or battery enclosure.
Note: For best system performance, ensure that positive and negative battery cables
are installed in close proximity to each other. UL listed angle type lugs may be
vertically stacked when paralleling battery cables
