Battery Bank Requirements
The DC voltage of the Conext XW+ Inverter/Charger 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.
Battery Cable Requirements
Battery cable
length
Cable runs should be kept as short as practical. Length should not exceed 10
feet (3 m). 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+ Inverter/
Charger as close as possible to the battery room or battery enclosure.
Note: The minimum recommended battery bank is 400 Ah per inverter/charger.
The Conext XW+ Inverter/Charger 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 10
volts, the Conext XW+ Inverter/Charger will not operate.
WARNING
OVERHEATING OF DC TERMINALS AND CABLES
Overheating of the DC terminals or DC cables to dangerous temperatures may
occur due to improper installation.
• Do not put anything between the cable lug and the terminal surface.
• Do not over-tighten connections; observe all recommended torque values.
• Do not apply any type of anti-oxidant paste until after the cable connection is
tightened.
• Do not under size cables; install cables sized in accordance with national
electrical code requirements.
• 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.
• 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 or serious injury.
Note: For best system performance, ensure that positive and negative battery
cables are installed in close proximity to each other.
