Using the Low Battery Cut Out and LBCO Delay Settings

The Inverter Settings Menu contains settings that control when the XW Inverter/
Charger turns on and off when it is inverting.

Item Description
Low Batt This setting controls when the inverter turns off due to a low battery voltage
Cut Out condition. The inverter will turn off only after this level has been reached
for the period of time set by the LCBO Delay. This setting is not
temperature compensated.
LBCO LBCO Delay controls how long the inverter is allowed to operate at or
Delay below the Low Battery Cut Out level before turning off due to a low battery
voltage condition. The inverter will turn off only after the Low Batt Cut Out
level has been reached for this uninterrupted period of time.
Once the inverter has shut off, the battery voltage must rise 4 volts above
the Low Batt Cut Out setting for inverter operation to resume.
High Batt High Batt Cut Out sets the maximum battery voltage at which the inverter
Cut Out will operate. If the battery voltage exceeds this limit for more than 1
minute, the inverter displays a fault message (F49) and shuts down. The
inverter will not support AC loads when in this condition. If a qualified AC
source is present, the unit passes AC through to the loads. The inverter
automatically restarts when the voltage drops to 3 volts (24-volt system) or
6 volts (48-volt system) below the High Batt Cut Out setting. If battery
voltage continues to rise after shutdown, an external charger may still be
charging the batteries. The XW Inverter/Charger cannot control how
external chargers operate.
Search Search Watts sets the inverter's search sensitivity when Search mode is
Watts enabled. When a load larger than this setting is present, the inverter turns
on. Enabling Search mode from the Setup Menu (see page 3–2) can
minimize power draw from the battery during periods of low demand from
loads. Also see "Using Search Mode" on page 3–8.
Search Search Delay sets the time between search pulses. When searching for
Delay loads, the XW Inverter/Charger sends out search pulses to determine if a
load is present. If the XW Inverter/Charger finds a load above the Search
Watts setting, the inverter comes on. XW Inverter/Charger power draw
while in Search mode decreases when Search Delay is increased, but the
inverter's response time to active loads is reduced.
For default settings, see "Inverter Menu" on page B–3.
The Low Batt Cut Out setting is the lowest voltage level acceptable for battery 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 transfers any available AC source (generator or grid) to the charger to
