Using the Low Battery Cut Out and LBCO Delay Settings

The Low Batt Cut Out setting is the lowest battery voltage level acceptable for

use by the inverter. When the batteries discharge to the Low Batt Cut Out

setting, and are held at or below this level for the LBCO Delay time, the inverter

output shuts down and connects any available AC source (AC1 or AC2) to the

charger to bring the battery level back above the Low Batt Cut Out setting. After

shutdown, the inverter does not support loads on AC OUT, and AC loads must be

stays below the LBCO voltage for more than 24 hours, the Conext XW+ shuts

down.

• If using the Conext Automatic Generator Start system, it is recommended to

set the Conext AGS voltage trigger setting higher than the Conext XW+ Low

Batt Cut Out voltage.

• Although not recommended, if using the Conext Automatic Generator Start

system with the start trigger set to the same voltage as the LBCO voltage, do

not set the LBCO Delay for less than the amount of time it takes the generator

to start and connect.

Otherwise – in both of the scenarios above – inverter output turns off before the

generator automatically starts, causing the battery voltage to recover slightly.

This may then stop the Conext AGS from starting the generator or result in the

Conext XW+ cycling on and off multiple times before the generator automatically

starts.

Using Search Mode

Why use Search

mode?

Search mode allows the inverter to selectively power only items that draw more

than a certain amount of power, which can result in energy savings. The Conext

XW+ has a no-load power draw of about 28 watts. Enabling search mode

reduces this power draw to less than 8 watts. Search mode operates differently in

single-unit and multi-unit installations.

WARNING

ADVANCED CONFIGURATION HAZARD

Advanced menu settings should be used by qualified personnel only.

Three phase operation should be configured by qualified personnel only.

Consult with the local utility before enabling Conext XW+ sell mode or grid

support functions.

Do not change these settings unless you are under the supervision and

direction of qualified personnel.

Failure to follow these instructions can result in death or serious injury.
