Recharging Your Batteries When Low Battery Light Illuminates
Low battery If the Low Battery light illuminates on the XS400 while it is operating,
your battery level is low (less than 10.7 volts). As long as the Inverter ON
light is illuminated on the XS400, the unit will continue to supply inverter
power to your appliances.
However, Xantrex highly recommends that you recharge your batteries.
Turn off your appliances and recharge your battery. When the Low
Battery light turns off (12.6 volts), you can restart your appliances. See
“Restarting or Operating Multiple Appliances”.
Importance of
recharging
Xantrex recommends that you recharge your batteries before they are
50% discharged. This gives them a much longer life cycle than recharging
them when they are almost completely discharged. See “Battery State of
Charge” on page B–8.

Recovering from Low Battery Voltage Shutdown
If the Low Battery light illuminates and the Inverter ON light on the
XS400 turns off when you are operating the unit, the XS400 has shut
down due to low battery voltage (10.3 volts). Output power is interrupted.
To recover from a low battery voltage shutdown:
1. Turn off your appliances and recharge your battery.
2. When the Low Battery light turns off (12.6 volts) and the Inverter ON
light illuminates, you can restart your appliances.
Restarting or Operating Multiple Appliances
The XS400 can handle several appliances simultaneously as long as they
do not draw more than 400 watts in total.
To restart or operate several appliances:
◆ Turn them on separately after the XS400 has started.
This action ensures that the XS400 does not have to deliver the
starting current for all the loads at once and helps to prevent an
overload shutdown.
