5 Operating the XPower 150
Operating Statuses
This section describes normal operation as well as problems
that could occur when you use the inverter. If you have a
problem, see “Troubleshooting” on page 12.
• Normal Operation When you connect the inverter to
your vehicle’s 12 volt outlet and turn on the On/Standby
switch, the green
PWR light comes on and AC power is
available at the outlet.
The inverter shuts down automatically in response to
low battery voltage, high battery voltage, AC overload,
overheating, or a short in the AC output.
• Low Battery Voltage Alarm and Shutdown As the
battery discharges, its voltage decreases.
When the inverter senses that the voltage at its DC input
has dropped to 10.7 volts, it sounds an alarm. This gives
you time to shut down computers or other sensitive
devices. If you ignore the alarm and the DC input drops
to 10.0 volts, the inverter shuts down the AC load being
operated. The
PWR light stays on, the alarm stays on, and
the light comes on. The low battery voltage
shutdown feature saves the battery from excessive
discharge, which can prevent you from starting your
vehicle, or more seriously, damage the battery.
• Possible shutdown when the vehicle’s engine is
started The XPower 150 will operate while your
vehicle’s engine is running, but the normal voltage drop
